Transmission Repair & Rebuilds
We Fix Yours. We Don't Just Swap It.
Not Another Exchange Unit
We don't work that way.
We diagnose the actual problem. We test. If a rebuild is needed, we send your transmission to our builder — a specialist with 49 years of experience — who disassembles it, documents what's wrong, and fixes what needs fixing. You get pictures. You get options. You get your transmission back, built right.
Exchange Units Are a Gamble
1. Your transmission fails
2. Shop orders a remanufactured unit from a supplier
3. Your transmission gets pulled, exchange goes in
4. Your original becomes someone else's 'remanufactured' unit
Unknown Quality
You don't know who rebuilt the exchange unit or how well
Unknown History
You don't know what was actually wrong with it before rebuild
Limited Warranties
Exchange units often come with fine print and limited coverage
Overpaying
You're paying for a complete transmission when yours might only need specific repairs

Custom Rebuilds by a 49-Year Specialist
1. Diagnosis First
We don't guess. We test the transmission, check codes, inspect fluid condition, and identify the actual failure point. Sometimes it's not even the transmission — it could be electrical, a sensor, or a linkage issue.
2. Disassembled and Documented
If internal work is needed, we send your transmission to our builder. He disassembles it completely and documents what he finds — with photos. You see exactly what failed and why.
3. You Get Options
Maybe it's a minor repair. Maybe it needs a full rebuild. Maybe you want upgrades while it's apart. We give you the information and let you decide.
4. Built to Your Specs
Your transmission gets rebuilt with quality parts, proper tolerances, and any upgrades you've chosen. Not a mystery unit from a warehouse — yours, done right.
More Than Stock
Since we're rebuilding your transmission anyway, this is the time for upgrades
Firmer, faster shifts that reduce clutch wear and improve durability.
For towing, hauling, or added power. Built for how you actually use the vehicle.
Improved shift quality, faster engagement, and better durability under load.
Built for trucks and performance applications. Handles more torque, lasts longer.
Transmissions built to handle diesel torque. Common for Cummins, Duramax, PowerStroke.
If you've added a tuner, bigger tires, or tow regularly, a stock rebuild might not cut it.

Signs Your Transmission Needs Attention
Don't wait — transmission problems rarely fix themselves
Engine revs but vehicle doesn't accelerate
Harsh engagement or hesitation between gears
Vibration or grinding during shifts
Transmission or check engine light illuminated
Red or brown fluid under the vehicle
Overheated fluid has a distinct burnt odor

Frequently Asked Questions
Common questions about transmission repair
Should I rebuild or replace my transmission?
We prefer rebuilding your transmission over installing an exchange unit. With a rebuild, we fix exactly what's wrong, you see documentation of the failure, and you can add upgrades while it's apart. Exchange units are unknown quality from unknown sources. A custom rebuild by our 49-year specialist is typically better value and better quality.
How much does a transmission rebuild cost?
Transmission rebuild costs vary significantly based on the transmission type and what's actually wrong. A minor repair might be $1,500-2,500, while a full rebuild with upgrades could be $3,500-6,000+. We diagnose first and give you exact pricing before any work begins.
Can you repair CVT transmissions?
We diagnose CVT issues and perform fluid services. For internal CVT repairs, we'll advise whether repair or replacement makes more sense for your specific situation. CVT rebuilds aren't always cost-effective compared to replacement, depending on the failure.
What are the warning signs of transmission problems?
Common signs include slipping (engine revs but vehicle doesn't accelerate), hard or delayed shifts, grinding or shaking during shifts, transmission warning light, fluid leaks, burning smell, or unusual noises. Don't ignore these — transmission problems rarely fix themselves and usually get worse.
Do you work on diesel truck transmissions?
Yes. We service and rebuild heavy-duty transmissions including Allison, Aisin, Ford TorqShift, Ram 68RFE, and GM units. Diesel trucks put extra stress on transmissions, especially when towing. We can build yours to handle the load.
