Text Unit DetailsGM Transmissions
Common GM units supported for rebuild and upgrade work.
GM truck, SUV, classic, and heavy-duty applications are among the most common supported work. Final direction depends on vehicle use, internal condition, converter choice, and build level.
4L60E / 4L65E / 4L70E
Common GM truck and SUV transmissions with stock, daily-driver, upgraded, and stronger reliability-focused build options.
TH350
Reliable 3-speed automatic used in classic applications, hot rods, older trucks, and simple non-overdrive builds.
TH400 / 3L80
Heavy-duty 3-speed automatic known for strength, durability, and use in higher-load or classic performance applications.
4L80E / 4L85E
Heavy-duty overdrive units commonly used in towing, work trucks, swaps, and stronger GM drivetrain builds.
6L80 / 6L90
Accepted case-by-case depending on condition, scope, programming needs, parts situation, and whether the job is a good fit.
Ford Transmissions
Ford units accepted depending on application and condition.
Ford transmission support depends heavily on the vehicle, failure type, parts availability, electronics, and whether the repair scope is realistic.
AOD / AODE
Light-duty Ford overdrive units with rebuild options available depending on application, condition, and parts needs.
4R70W / 4R75W
Common Ford transmissions used in trucks, SUVs, and rear-wheel-drive platforms with rebuild support available.
E4OD / 4R100
Medium-duty Ford overdrive units accepted depending on vehicle, condition, hard parts, and build requirements.

Classic Ford 3-speed automatic accepted for supported rebuild work in classic and older performance applications.
C6
Strong classic Ford 3-speed automatic accepted for supported rebuild work, including truck and classic applications.
Chrysler / Dodge / Jeep
Hydraulic, electronic, and truck units reviewed by application.
Chrysler, Dodge, and Jeep transmission work is accepted selectively. Some units are straightforward, while others require more caution due to electronics, diesel use, hard-part cost, and failure pattern.
904 / 998 / 999
Light-duty Chrysler automatics commonly found in older applications, accepted for supported rebuild work.
30RH / 32RH
Common Jeep and Dodge hydraulic units with rebuild support depending on application and condition.
42RE / 44RE
Accepted depending on application, symptoms, electronics, hard parts, and overall condition.
46RH / 46RE
Gas and diesel truck applications accepted case-by-case depending on build requirements and internal condition.
47RH / 47RE / 48RE
Diesel and heavy-use applications reviewed based on power level, converter needs, hard parts, and customer expectations.
68RFE
Only accepted after inspection due to complexity, parts cost, failure pattern, and the importance of proper build direction.
Additional Drivetrain Work
Transmission work is only part of the drivetrain.
Transfer cases, differentials, bench builds, and supporting drivetrain components may also be accepted depending on the unit, vehicle, symptoms, and parts availability.
If the problem feels like grinding, binding, popping, whining, vibration, leaking, no 4WD engagement, or drivetrain noise, send the details before assuming it is only the transmission.
Ask About Drivetrain WorkTransfer Cases
Inspection, reseal, and rebuild work available for select transfer cases.
Differentials
Front and rear differential service and repair accepted depending on application.
Bench Builds
Bring in a supported unit for teardown, inspection, and rebuild without vehicle-side labor.
Other Units
Additional transmissions and drivetrain work may be accepted after review.
Important Fit Note
The listed unit is only the starting point.
The same transmission can need a very different repair depending on the vehicle, symptoms, mileage, prior work, internal damage, converter condition, cooler contamination, electronics, towing use, tire size, and customer expectations.
Some units are accepted quickly. Some need inspection first. Some are better declined if the scope does not make sense. That selectivity is part of keeping the quality high.

Supported Unit Questions
Common questions before sending your vehicle details.
Do you rebuild every transmission listed?
No. Listed units are supported or commonly requested, but final acceptance depends on application, condition, parts availability, and build scope.
What if my transmission is not listed?
Send the vehicle details anyway. This list is not complete, and additional units may be accepted case-by-case.
Why are some units case-by-case?
Some transmissions require programming, expensive hard parts, special tools, or inspection before accepting the job confidently.
Do you accept bench builds?
Yes. Supported transmissions can be brought in for bench rebuild work after the unit and scope are reviewed.
