Scan & pressure diagnosis
Transmission control modules store codes and record adaptive data. We pull the codes, watch live pressure and solenoid data during test drives, and compare against factory spec before we touch anything mechanical.
Transmission Repair & Service
Hard shifts, slipping, delayed engagement, fluid leaks, transmission warning lights — the transmission is telling you something. We diagnose accurately and repair only what's needed, not push a rebuild on every job.
Why it matters
A transmission problem isn't always a rebuild.
Next to the engine, the transmission is the most expensive component on the vehicle — and that makes it the most common place for misdiagnosis to cost a customer thousands. A rough shift might be a failing solenoid that costs a few hundred to replace. A slipping transmission might be low fluid from a $50 leak repair. A no-shift might be a speed sensor the size of a spark plug. Or it might be internal damage that really does need a rebuild. The right answer depends on a proper diagnosis — not a shop that quotes "transmission" for every symptom.
Our diagnostic process starts with the scan tool, pulls transmission codes from the TCM, reads live solenoid and pressure data while we drive, and checks adaptive learning values. We inspect the pan for debris, check the fluid condition, and test line pressure. Only after all of that do we commit to a direction — and when the answer is "this can be fixed with a solenoid and a fluid service," we don't pretend it needs a rebuild.
When a rebuild genuinely is the right call — usually on high-mileage units with internal damage, burned clutches, or converter failure — we do it to the standard we'd want for our own vehicles. Proper teardown, inspection of every component, updated parts where the manufacturer has revised them, and a break-in procedure before the vehicle goes back to you. Every rebuild is backed by our 24-month, 24,000-mile nationwide warranty.
What's involved
From fluid service to full rebuild.
The transmission work we handle covers every level of repair — from the smallest scheduled maintenance to a complete replacement of an internally failed unit.
Solenoid & valve body service
Most shift-quality and engagement problems on a transmission with otherwise healthy internals are solenoid or valve body issues. Replacing a solenoid or rebuilding the valve body is a small job with big results — and avoids an unnecessary rebuild.
Torque converter service
Converter shudder, lockup problems, and stall-speed issues point at the torque converter. Sometimes it's a TCC solenoid or a software update; sometimes the converter itself is failing. We diagnose properly and replace the converter when the converter is the problem.
Fluid leak repair
Pan gaskets, axle seals, output shaft seals, cooler lines, and torque converter seals — all common leak points. Low fluid destroys a transmission; catching a leak early is the cheapest transmission work you'll ever do.
Fluid service & filter
Fresh manufacturer-specific ATF, a clean pan, a new filter, and a thorough inspection of the debris you pulled out of the old pan — that pan tells a story about how the transmission is wearing inside.
Manual clutch replacement
Clutch chatter, slip under load, pedal that won't engage near the floor, or grinding going into gear — clutch replacement on a manual transmission includes disc, pressure plate, throw-out bearing, and pilot bearing. We resurface or replace the flywheel when spec requires it.
Transmission rebuild
When the unit has internal damage — burned clutches, worn planetary gears, pump failure — we rebuild it. Every internal seal, clutch, band, and bushing is replaced or inspected to factory spec, with any manufacturer updates applied.
Transmission replacement
When a rebuild isn't economical — or when the unit isn't rebuildable — we install a quality replacement, either remanufactured or used-tested depending on what's right for the vehicle and your budget.
Break-in & adaptive relearn
After any major transmission work, the TCM needs to relearn shift patterns and we follow a proper break-in procedure before calling it done. A fresh transmission shipped out without relearning can feel worse than the one you came in with.
Signs it's time
Don't wait for a tow.
Transmissions almost always warn you before they fail. Catching these early is the difference between a small repair and a major one.
Slipping between gears
The engine revs but the vehicle doesn't accelerate the way it should. On an automatic, that's clutch pack slip or low fluid pressure. On a manual, it's a worn clutch. Either way, the problem gets worse — and more expensive — the longer you drive it.
Hard shifts or clunking
A firm thump between gears where the vehicle used to shift smoothly means pressure is out of spec, a solenoid is sticking, or clutches are hanging. Diagnosed early, this is often a valve body or solenoid repair.
Delayed engagement
Put it in drive and wait… wait… then it engages. That delay is a seal that's not holding pressure or fluid that's too low. It's a warning. Ignoring it leads to a rebuild.
Transmission warning light
A flashing or solid transmission warning light, a "service transmission" message, or the vehicle dropping into limp mode — all reasons to stop driving and get it scanned. The codes tell us what the transmission is protecting itself from.
Red fluid on the driveway
Fresh ATF is red. A spot where you parked means the transmission is leaking — and even a small leak can empty the pan in a few days of driving. Catching a leak at a seal is dramatically cheaper than replacing a burned-up transmission.
Burnt or dark fluid
New ATF is clear red. Burned ATF is dark brown and smells like over-cooked marshmallow. When the fluid is that color, the transmission has been overheating internally — the clutches have been slipping, and the damage is already starting.
Shudder at steady speed
A light, rhythmic shake at 40-55 mph that smooths out when you accelerate or brake is classic torque converter lockup shudder. Sometimes just a fluid service and a software update fix it; sometimes the converter needs replacement. Easy to diagnose.
Grinding going into gear (manual)
A manual transmission that grinds going into first or reverse, or that fights you on downshifts, is usually a clutch that isn't fully releasing — hydraulic problem, worn throw-out bearing, or a clutch disc that's done. We diagnose which.
Get it diagnosed before it gets worse.
An honest transmission diagnosis is cheaper than a rebuild you didn't need. Bring it in, we'll tell you what's really going on.
Related services
Often goes hand-in-hand with.
Transmission Flush
Scheduled fluid service is the single best thing you can do for transmission life. The right time for it is before there's a problem — not after.
Differential Service
In 4WD and AWD vehicles, differentials and transfer cases share duty with the transmission. Service them together when mileage or symptoms call for it.
Diagnostics
Transmission codes, live data, and adaptive learning are where proper transmission diagnosis starts — and where we avoid quoting parts you don't need.
