TCU Repair FAQ
What is a TCU and how do I know mine is bad?
The TCU (Transmission Control Unit), also called a TCM (Transmission Control Module), is the computer that controls automatic transmission behavior — shift timing, solenoid activation, and torque converter lock. When it fails you typically see P0700-series codes, harsh or delayed shifts, transmission stuck in one gear (limp mode), or a U-code communication fault pointing to the TCM on your scan tool.
Will the repaired TCU be plug-and-play?
Yes. We program the TCU to your specific VIN and perform shift calibration before shipping it back. On most vehicles it installs without a dealer visit. Some platforms require a relearn procedure after installation — we include instructions specific to your vehicle.
Can you fix limp mode caused by the TCM?
In most cases, yes. Limp mode triggered by TCM failure — where the transmission locks into second or third gear — is a common fault we repair. We identify the root cause at the component level rather than just clearing codes.
How long does TCU repair take?
Most TCU repairs are completed in 48–72 business hours from receipt. Rush 24-hour service is available for an additional $75–$100. We ship the same day repair is completed.
What if you can’t fix my TCU?
