TCM / Transmission Control Module Repair
Harsh shifting, stuck in limp mode, no communication with the TCM — we replace the failed solenoid drivers and processor circuits so your original adapts and tuning stay intact.
TCM failures look like transmission problems but almost always trace back to blown solenoid driver ICs or cracked solder joints on high-current circuits inside the control module. Replacing the transmission won't fix it.
We rebuild the TCM at component level and bench-test against a transmission simulator on every solenoid channel before it ships back. Adapt values and shift tuning are preserved.
Common symptoms
- Transmission stuck in limp mode (3rd gear only)
- Harsh or delayed shifts
- No upshift / no downshift
- Transmission codes that won't clear
- No communication with the TCM
- Slipping or flaring between gears

FAQ
No. Because we return the original module, adapts and learned shift behavior are preserved.
No programming needed. Bolt it back on, clear any old codes, and drive.
