Transmission Repair that starts with the truth
A transmission problem can be anything from a dirty fluid and filter to a clutch pack that has burned itself out under a loaded trailer. Too many drivers are told they need a full rebuild before anyone has checked the simple causes. Our Transmission Repair service begins with a scan, a fluid inspection, and a road test, so we can tell you whether you need a service, a valve-body fix, or a rebuild. You get the cheapest fix that actually solves the problem, and a clear picture of what the next few years will demand.
- Scan, fluid inspection, and road test before any quote
- Service, repair, or rebuild — whichever the truck truly needs
- Rebuilds upgraded for towing and hot Valley conditions
Signs your transmission is in trouble
Transmissions rarely fail with no warning. Catch these early and you may avoid a rebuild entirely.
- The truck slips, flares, or hesitates between gears
- Shifts land hard or the transmission hunts for a gear
- Fluid is dark, burnt-smelling, or shows metal sparkle
- A puddle of red fluid sits under the truck in the morning
- The check-engine or transmission-temp light comes on
- The truck will not engage drive or reverse when cold
What transmission service includes
The scope grows with the diagnosis, and everything is quoted before we touch the pan.
- Computer scan, live-data capture, and a full road test
- Fluid and filter service with the correct manufacturer fluid
- Pan drop, magnet cleaning, and pan-gasket replacement
- Solenoid, sensor, and valve-body diagnosis and repair
- Torque-converter replacement on shudder or stall faults
- Clutch inspection and replacement on manual trucks
- Full rebuilds with upgraded clutches and bands for towing
- Cooler-line flush and a transmission-cooler check
How a transmission repair works
The same careful sequence keeps us honest. We only rebuild what a service cannot fix.
-
1. We scan the computer and read stored and pending codes.
-
2. We check fluid level, color, and smell, and look for debris.
-
3. A road test captures shift points and any slip under load.
-
4. We quote the range of fixes from service up to rebuild.
-
5. You approve, and we start with the least invasive repair.
-
6. We re-test and adjust shift quality after the repair.
-
7. We flush the cooler lines and confirm no leaks before delivery.
What transmission repair costs
A fluid and filter service is a small bill; a solenoid or valve-body repair sits in the middle; a full rebuild or replacement is the big one. Prices vary by year, make, trim, and whether the unit is a light-duty automatic or a heavy towing transmission, so any quote is a range until we open it up. We always show the service option first, because many rough-shifting trucks are fixed without a rebuild at all.
- Fluid and filter service
- $180–$380
- Solenoid or sensor repair
- $350–$900
- Valve-body repair or replacement
- $800–$1,800
- Full rebuild, most light trucks
- $2,800–$5,500
- Remanufactured replacement unit
- $3,500–$6,500
Transmission fitment by vehicle
Automatic families differ widely. The fluid matters as much as the parts. A six-speed and an eight-speed can share a body style but take completely different fluid and service procedures, so we look up your exact application instead of assuming.
- Ford F-150, F-250, and Ranger automatics
- Chevy Silverado, GMC Sierra, and Chevy Colorado
- Ram 1500, 2500, and 3500 with gas or diesel engines
- Toyota Tacoma, Tundra, and 4Runner
- Jeep Wrangler, Gladiator, and Grand Cherokee
- Nissan Frontier and Titan, plus most SUVs
Why transmissions struggle in the Valley
Heat is the number one killer of automatic transmissions, and South Texas supplies plenty of it. Stop-and-go on the expressway, loaded trailers in summer, and constant stop-start driving around town all push fluid temperatures toward the limit. When fluid overheats, it oxidizes, stops lubricating properly, and slowly cooks the clutches. A service interval that ignores Valley heat is how a healthy transmission becomes a rebuild. Keeping fluid fresh and the cooler working is the cheapest insurance a truck owner can buy.
- Summer heat and towing raise fluid temperatures fast
- Burnt fluid is a symptom, not just a smell
- Fresh fluid and a clean cooler prevent most failures
What to expect during your visit
You will not be left guessing. We explain what we found at each step, show you the fluid and any debris, and put the options in writing with real ranges. If a service is the right choice, we say so even though a rebuild would pay us more. If a rebuild is truly needed, we walk you through what gets replaced, how long it takes, and how the upgraded parts handle towing better than the originals did.
- Written options with real price ranges, not pressure
- Old parts shown and explained on request
- A firm timeline before we start the teardown
Manual versus automatic service
Manual and automatic transmissions fail in different ways and need different service, so the diagnosis starts by knowing which one you have and how it behaves. An automatic usually complains through shift quality, slipping, or fluid condition, while a manual shows wear through clutch feel, grinding gears, or a noisy bearing. On a manual truck we inspect the clutch, flywheel, and hydraulics together, because replacing a clutch without checking the flywheel often brings the truck right back. On an automatic we test pressure and shift timing with live data before opening anything. Either way, the goal is to find the specific worn part rather than replacing a whole assembly by default. That approach matters most on Valley trucks, where a rebuilt transmission is a major expense and a fluid service or a valve-body repair often solves the exact complaint that brought the truck in. When a rebuild is genuinely required, the estimate explains what the upgraded internals do for towing. Either way, the recommendation and its reasoning reach you in writing before any work starts.
- Automatic: shift quality, slipping, and fluid condition
- Manual: clutch feel, gear grinding, and bearing noise
- Manual jobs include flywheel and hydraulic checks
- Automatic jobs test pressure and shift timing first

Questions from the bay
How much is a transmission repair?
Fluid and filter service starts near $180, a solenoid or valve-body repair runs in the middle, and a full rebuild typically lands between $2,800 and $5,500. The exact figure depends on the truck and what we find inside.
How long does a rebuild take?
Most rebuilds take three to five business days once parts arrive, and a service or solenoid repair is often a single day. Fleets can schedule overnight drop-off so a unit is ready for the next shift.
Rebuild or replace with a remanufactured unit?
We compare both honestly. Rebuilding keeps your original case and lets us upgrade the weak points; a reman unit can be faster when time matters more than cost. You see both options in writing.
Can a fluid change fix a slipping transmission?
Sometimes yes, especially if the fluid is burnt and the clutches are still intact. If the fluid is full of metal or the clutches are gone, a service will not save it, and we tell you that up front.
Why does my truck shudder at highway speed?
A shudder under light load is often the torque converter locking and unlocking as it fails. It can also come from ignition or fuel faults, so we scan and test before blaming the transmission.
Do you work on diesel transmissions?
Yes. Heavy-duty diesel automatics from Ford, Ram, and GM are common here, and their higher torque makes fluid condition and cooling even more important. We service and rebuild them with parts rated for the load.
How often should transmission fluid be changed?
For most trucks, every 30,000 to 60,000 miles, and sooner if you tow regularly in summer heat. Severe-duty use in the Valley is exactly the case that shortens the interval.
Can you rebuild a manual transmission?
Yes. We inspect and replace clutches, synchros, and bearings on manual trucks, and we check the flywheel and hydraulics at the same time so the repair holds up.
Will a rebuild void my warranty?
A quality rebuild does not, but poor work with the wrong parts can. We use parts and fluid that meet or exceed the original spec, and we document everything so your records stay clean.
