Real-world transmission work
Built for the weak link everyone notices when it lets go.
Some customers need a stronger unit for a harder combination. Others just need a daily driver or tow rig to shift correctly again. Foulks Performance handles both without turning the conversation into vague shop talk or padded estimates.
What's included
Transmission work from diagnosis to handoff.
Diagnosis
Proper diagnosis before parts are ordered — slip, delayed engagement, or harsh shifts each point to different fixes.
Automatic rebuilds
Full rebuilds on 4L60E, 4L80E, TH350, TH400, 6L80, 4R70W, and other common GM / Ford / Mopar automatics.
Performance builds
Upgraded internals for transmissions that have to hold up behind higher power levels and aggressive shifts.
Diesel transmissions
Allison and other heavy-duty diesel transmissions built to handle towing, pulling, and work-truck duty.
Cost-aware sourcing
Used and remanufactured options discussed honestly when a full rebuild is not the right answer for the situation.
Swap integration
Transmission pairing and installation for engine swap projects including crossmember, driveshaft, and cooler work.
Who it's for
Truck owners, racers, and drivers with a transmission that is not right.
A failing transmission is one of the most expensive problems a vehicle can have, and the wrong decision on rebuild versus replace can cost thousands. Foulks Performance talks through the options honestly — sometimes a used unit is the right call, sometimes a rebuild is, and sometimes it is a specific part that needs to be addressed.
- Work trucks with failing automatics
- Performance vehicles needing upgraded internals
- Daily drivers with shifting or slipping problems
- Swap projects needing transmission integration
