No tow truck, no shop waiting room. I come to your driveway, office, or fleet yard anywhere in Broward — Fort Lauderdale, Coral Springs, Plantation, Pompano Beach, Hollywood, Tamarac, Margate, Deerfield Beach — and most transmission diagnostics happen the same day you call.
What Your Transmission Does and How It Breaks
Your transmission takes the engine's power and delivers it to the wheels at the right gear for the right speed. An automatic shifts on its own using hydraulic pressure and electronic solenoids. A manual you shift by hand. A CVT (continuously variable transmission) has no fixed gears — it uses a belt and pulleys to dial in the right ratio.
All three depend on transmission fluid to stay cool, lubricated, and hydraulically powered. Dirty fluid, low fluid, a leak, a clogged filter, a bad solenoid, or worn clutch plates inside are the common killers.
In Broward County heat and traffic, transmissions work harder. Stop-and-go on I-95 in July cooks the fluid. Sitting in traffic with your foot on the brake pushes transmission temperature past 200°F, and the rule of thumb is that every 20 degrees over about 175°F cuts fluid life roughly in half. Fluid that's rated for years in a mild climate can be worn out in a couple of Broward summers.
Dealerships see a slipping transmission and say "you need a $4,000 rebuild or a $5,000 replacement." Sometimes that's right. But most of the time the real problem is low fluid from a slow leak, dirty fluid that needs changing, or a bad sensor feeding the solenoids wrong information. I find out which one it is before you spend $4,000 on nothing.
Common Transmission Problems and What They Cost
- Transmission fluid leak — Spot under the car, low fluid warning, slipping in the heat. Location and size matter. A seal that costs $200 to replace is a different job than a pan gasket ($300–500) or a cracked cooler line ($400–800 installed). I find the leak first and give you the price before touching anything.
- Slipping gears — Engine revs but the car doesn't pull, or it flares between shifts. Could be low fluid (fill it, done), dirty fluid (change it, $200–400), a bad torque converter clutch solenoid ($300–600), or worn clutch plates (that's the $2,000–4,000 repair). I check pressure, scan the codes, and tell you which one.
- Delayed shifts or stuck in one gear — Won't shift up or down, or shifts slow. Usually a solenoid fault, a clogged filter, or low fluid. Solenoid: $200–400 parts and labor. Filter and fluid service: $300–500. Low fluid from a leak: find and fix the leak first.
- Transmission noise — Whining, grinding, or clunking. Whine is often low fluid or the torque converter. Grinding is internal wear, which is more serious. Clunking is often engine mounts or the driveline, sometimes not the transmission at all. I listen to it and tell you what system it's coming from.
- Check engine light with transmission codes — Codes like P0700, P0740 and P0755 point to transmission electrical problems: a sensor, a solenoid, wiring, or the transmission control module. The scan tells me which. Some are $150 fixes, some are $500+. More on codes on my check engine light page.
- Burning smell — Overheated transmission fluid smells burnt. It means the transmission is running hotter than it should and the fluid is breaking down. You need a cooler check or a fluid change soon. This one is urgent — don't ignore it.
Transmission Repair vs Replacement — Cost & Decision
Dealerships love pushing replacement because it's the biggest ticket in the building. Here's the real breakdown:
- Fluid change (drain and fill): $200–400. Takes 1–2 hours. Renews roughly 30–50% of the fluid, because the torque converter and cooler lines hold fluid the drain plug can't reach. Good preventive maintenance every 60,000 miles. Details on my transmission fluid change page.
- Transmission flush (machine exchange): $400–600. Swaps out 90%+ of the old fluid. Costs more than a drain-and-fill. Worth it when the fluid is burnt or badly degraded.
- Seal or gasket replacement: $300–800 depending on location. Fixes a leak without rebuilding anything. A pan gasket is the cheaper end. An output shaft seal takes longer.
- Solenoid or sensor replacement: $200–600. Electronics fail, you replace them. Most solenoid problems come in under $400.
- Torque converter replacement: $800–1,500. If the converter is what's causing the slip, replacing it is usually cheaper than rebuilding the whole transmission.
- Full transmission rebuild: $2,000–3,500. The transmission comes out, gets torn down, worn clutches, seals and bearings get replaced, and it goes back in. A used or remanufactured unit from another vehicle runs $1,200–2,000 plus $800–1,500 labor to swap.
- New OEM transmission: $4,000–6,000 installed. Only if the transmission is beyond rebuilding. Rare.
The diagnostic tells you which category you're in. Most problems land in the $200–800 range. Some need the rebuild. Very few need a brand-new unit. Anything that means pulling the transmission — torque converter, rebuild, swap — needs a lift, so it doesn't happen in your driveway. I tell you that straight, give you the diagnosis in writing, and quote and source the unit so you're not starting over at another shop.
BMW, Automatic, CVT, Manual — Different Transmissions, Same Rules
BMW automatic (ZF 6-speed and 8-speed) — The ZF gearboxes in BMWs are solid, but they run hot in Broward traffic. On high-mileage N52 and N54 cars the usual suspects are the mechatronic sleeve seal and pan gasket leaking — fluid drops, then shifts go harsh or it slips. I'd change the fluid every 60,000 miles no matter what the "lifetime fill" sticker says. The correct ZF fluid runs $20–35 a liter, a few times the price of generic ATF, but it's required — cheap fluid ruins these transmissions. A BMW transmission diagnostic is the same $120 as any car.
Everyday automatics (Honda, Toyota, Chevy, Dodge, Ford) — Most people down here drive an automatic. Toyota and Honda automatics generally hold up if you keep fresh fluid in them. Some domestic units — certain Ford, GM and Chrysler transmissions — are known for solenoid and valve body problems at higher mileage. The diagnostic is the same: check pressure, scan codes, tell you what's wrong.
CVT (Nissan, Subaru, newer Honda and Toyota) — CVTs use fluid to run a belt-and-pulley system instead of gears. They feel different — smooth acceleration with no shift "bump" — but fluid condition is everything. Low or worn-out fluid kills the belt fast. A replacement CVT runs $3,000–4,500, but a diagnostic can tell if the belt is starting to slip or if it's just a fluid problem.
Manual transmissions (rare in Broward) — Most manuals down here are older cars or imports. Problems are usually clutch wear (it slips, or engages high on the pedal), worn synchros (grinding when you shift), or worn bearings (noise). I drive it, listen, and feel the pedal, and I can tell you if it's a $600 clutch job or a $2,000 rebuild.
Why Mobile Transmission Diagnostic Beats the Dealership
Dealership: $150–250 diagnostic fee, quote usually says "rebuild or replace," labor at $180–220/hr, and your car sits 2–3 days.
Me: $120 diagnostic, credited to the repair if you go ahead. I tell you what's actually wrong and what it really costs. No tow, no waiting room — I come to you.
A dealer sees slipping and jumps to the $3,000 rebuild because that's their bread and butter. I see slipping and check pressure first. Low fluid from a leak is a $300–500 fix. A solenoid is around $400. Only when the pressure is low, the fluid is burnt, and the solenoids are being commanded correctly do I tell you it's worn inside.
That's why Broward contractors and fleet managers call me: when a repair does run $2,000, it's often half the dealership quote, and they know the number upfront.
The 90-Day Labor Guarantee
I guarantee the labor on all the transmission work I do for 90 days. If something I did goes wrong inside that window, I come back and fix it free. Parts carry the OEM or aftermarket warranty — I'll tell you what that is when I quote.
Transmission repairs have to prove themselves. In Broward heat, if there's going to be a problem, it usually shows up in the first week of driving. The 90 days has your back.
How to Book a Transmission Diagnostic
Call or text (203) 549-7058 with your year, make, model, and what the transmission is doing — slipping, noise, leak, delayed shift, or check engine light.
I'll confirm the $120 diagnostic and what day I can come — often same day. You pick the spot: your driveway, your fleet yard, your work lot. I bring the scan tool, pressure gauges, and fluid check kit. You get a written quote before any work starts. Cash and Zelle only.
CALL OR TEXT 203-549-7058What I Actually See on Broward Transmission Calls
Most of the transmission calls I take don't start with "my transmission is gone." They start with "it's doing something weird when it's hot." The car shifts fine at 7 in the morning in Coral Springs, then by the time you're crawling down I-95 past Commercial Boulevard at 5:30 it flares between 2nd and 3rd, the RPMs jump, and it catches with a bang. That pattern points to heat, and heat points to fluid, solenoids, or a valve body that's sticking once everything expands. Those are fixable in your driveway.
The other big one is the delayed engagement. You put it in Drive, nothing happens for two or three seconds, then it clunks in. On a car sitting in a Tamarac or Lauderhill apartment lot all week in 95-degree sun, that's usually low fluid from a slow cooler line or pan gasket leak. I've also pulled plenty of cars where somebody topped it off with the wrong fluid at a gas station, and a CVT does not forgive that.
Why the diagnostic is $120 and not free. A free code scan tells you there's a shift solenoid code. It doesn't tell you if the solenoid is bad, the wiring is chafed, or the fluid is so cooked the solenoid can't do its job. I check fluid condition, read live transmission temperature and line pressure where the car allows it, and road test it on real Broward roads. That $120 is credited toward the repair, and it's the reason I can tell you "this is a $350 solenoid job" instead of a shop telling you "it needs a $4,500 transmission" without looking.
Florida heat is the number one transmission killer down here. Fluid life drops fast once temperatures sit above 175°F, and stop-and-go on I-595, Sunrise Boulevard, or US-441 keeps it there for an hour at a time. If it's slipping or flashing a check engine light, don't wait. If your temperature gauge is also climbing, read my car overheating help page too, because the transmission cooler runs through the radiator and one problem feeds the other. For cars that just need fresh fluid, see transmission fluid change in Broward.
Common Questions About Transmission Repair
How much does a transmission diagnostic cost?
$120. It covers a full scan of transmission codes, live data, line pressure readings where the transmission has a test port, fluid level and condition check, solenoid testing, a road test, and my recommendation. The $120 is credited toward the repair if you go ahead. Most people use it to get a real number before they walk into a dealership, and it regularly saves them from a rebuild they didn't need. You get the findings in writing, so if the job does need a transmission shop, nobody has to start the clock over.
Can you fix a transmission leak without a full rebuild?
Almost always. Most leaks are a seal or gasket. A pan gasket runs $300–$500. An output shaft or axle seal runs $400–$800. A cooler line runs $400–$800. A rebuild only comes up when the leak ran the fluid low long enough to do internal damage. I clean the area, find exactly where it's coming from, and give you one price for that one fix. I won't upsell you a rebuild you don't need.
Why does my transmission slip worse when the car is hot?
Fluid thins as it heats up, and thin fluid holds less pressure. If your fluid is already low or worn out, hot weather makes the slip worse. In a Broward summer, stop-and-go traffic can push transmission temperature past 210°F, and that's exactly when the slip shows up. I check fluid level and condition first — if it's low, we find the leak; if it's cooked, we change it. Either fix is usually under $400 and takes care of most hot-weather slipping.
Can I drive with a transmission leak?
Short term, if it's small. If you're losing about a quart a week, you've got a few weeks before it's low enough to overheat or start slipping — and you should be checking the level every few days. If it's leaving a real puddle, stop driving and call me. Damage happens fast once the level drops below the mark, because the pump starts sucking air and the clutches start burning. Don't gamble a $300 seal against a $3,000 rebuild — get the transmission fluid leak found and fixed.
Can you replace a transmission solenoid on my car?
Yes, on most cars. Some solenoids mount on the outside of the case and swap in about 30 minutes. Most sit on the valve body inside the pan, so I drop the pan, change the solenoid, put in a new filter and gasket, and refill — usually 2–3 hours. A single solenoid runs $200–$600 total. If several are failing, replacing the solenoid pack or valve body ($800–$1,200) can be the smarter fix, and I'll tell you that upfront.
Why does my transmission clunk when I shift from Park to Drive?
Usually worn engine or transmission mounts. When the transmission engages, the engine twists, and a broken mount lets it jump. It can also be driveline slack — worn U-joints, CV joints or differential — or, less often, internal transmission wear. I check the mounts while someone shifts, look at the driveline, and narrow it down. Mount replacement runs $200–$400. A clunk that's coming from inside the transmission is more serious and gets a closer look before anyone quotes anything.
How long does a transmission repair usually take?
Solenoid swap: 1–4 hours depending on where it lives. Fluid change: 1–2 hours. Leak seal: 2–6 hours depending on which seal. All of that happens on-site at your driveway, office or yard. Anything that needs the transmission pulled — torque converter, rebuild, or a swap — goes on a lift at a transmission shop and takes 3–7 days depending on parts. Either way, I give you a timeline upfront so you know when you'll have the car back.
What if my transmission goes completely bad? How much is a replacement?
Used transmission: $1,200–$2,000 for the unit plus $800–$1,500 labor, so about $2,000–$3,500 total. Remanufactured unit: $2,000–$3,500 plus $800–$1,200 labor, so about $2,800–$4,700. New OEM: $4,500–$6,500 installed. Most cars are best served by a used or reman unit, and I can source either and give you a timeline. Before we go there, the $120 diagnostic confirms it's actually dead — plenty of "dead" transmissions I've checked needed fluid or a solenoid.
Why does my transmission smell like burning?
Transmission fluid smells burnt when it overheats and starts breaking down. That means the transmission is running too hot. Could be low fluid from a leak, a clogged cooler, heavy traffic in Broward heat, or clutches slipping inside and making friction. It's urgent — don't take long trips. Call me for a same-day diagnostic, because driving on overheated fluid is how a fixable problem turns into a rebuild. Caught early, a fluid change and fixing the cause can be all it needs.
What if the transmission is slipping but the dipstick shows full fluid?
Fluid level is one thing, fluid condition is another. You can be full on old, burnt fluid and still slip. Or the transmission can be low on pressure from a worn pump, a clogged filter, a stuck valve, or internal wear. The $120 diagnostic includes pressure readings where the transmission has a test port, a fluid check, and live data, so I find out fast. A lot of the time it's worn-out fluid or a solenoid. Sometimes it's internal, and I'll tell you straight.
Do you come to me for transmission repair, or do I need a tow?
I come to you. Driveway, office lot, apartment complex, wherever the car is in Broward County. I bring the scan tool, the fluid, and the common solenoids and gaskets. The only time a tow makes sense is a full transmission replacement, and I'll tell you that up front before you pay for anything.
What are the first signs my transmission is going bad?
Slipping (RPMs climb but the car doesn't speed up), late or hard shifts, a delay going into Drive or Reverse, a burning smell, and red or brown fluid under the car. In Broward the first sign is usually that it only acts up after 20 minutes in traffic, when the fluid is hot.
Can a transmission problem cause a check engine light?
Yes. Shift solenoid codes, torque converter clutch codes, and gear ratio codes all turn on the check engine light, and some cars flash a separate transmission warning or go into limp mode. I read the transmission module directly, not just the engine computer, so I can see the real fault.
Is my CVT different from a regular automatic?
Very. A CVT uses a belt and pulleys instead of gears, it takes its own specific fluid, and it hates heat more than a normal automatic. Nissan, Honda, Toyota, Subaru and plenty of others use them. A shudder or whine from a CVT needs to be checked early, because the repair options shrink once the belt starts slipping.
What does limp mode mean?
The computer saw a problem it didn't like and locked the transmission in one gear, usually 2nd or 3rd, to protect itself. The car will move, but slowly and with high RPMs. Get off I-95 or the Turnpike and call me. Limp mode is often a sensor, solenoid, or low fluid, not a dead transmission.
How much does a transmission solenoid replacement cost?
Depending on the car, most solenoid jobs I do run about $250 to $600 with parts and labor. Some solenoids bolt on the outside of the case, and some sit inside the pan on the valve body. I quote the exact price after the $120 diagnostic, and that fee comes off the repair.
Should I get a transmission flush or just a drain and fill?
On most cars I do a drain and fill, sometimes two, because it's gentler on an older transmission with high miles. A full fluid exchange through the cooler lines makes sense on a healthy unit that's on schedule. I'll look at the fluid condition and mileage and tell you which one your car actually needs.
Why does my car jerk when it shifts from 1st to 2nd in traffic?
In bumper-to-bumper traffic the transmission shifts back and forth between 1st and 2nd constantly. Worn fluid, a sticking shift solenoid, or old software can make that shift harsh. A lot of cars also have a relearn procedure after a battery dies, and skipping it can cause rough shifts. I check all three.
