Send your VIN and the TCM label and we confirm the match before you pay.
How it works
This part is in our inventory and ready to ship. Share your VIN and we confirm fitment before you buy, then we’ll call you within about 30 seconds with your quote — or email it if we can’t reach you.
Signs your transmission control module has failed
- Stuck in limp mode (one gear), harsh or delayed shifts, or no upshift
- P0700 with U0101 (lost communication with TCM) or internal TCM codes (P0603, P0605, P062F)
- Shift quality changes once the truck is hot
- No reverse or intermittent neutral with no mechanical noise
- Transmission warning light after a fresh fluid change and a clean pan
Before you order
- Send the part number from the TCM label and your VIN — Aisin and Allison modules are calibration-specific to engine, axle ratio and model year.
- Allison TCMs (GM) need programming with your VIN after installation; Isuzu Aisin units are usually plug-and-play with the correct part number; ask us about your Ford or Ram.
- Confirm the shift solenoids, transmission range sensor and wiring aren’t the real cause — a solenoid code is not a TCM code.
- Change fluid and filter and clear adaptives after installation so the module learns your transmission.

Frequently asked questions
Do you sell used Transmission Control Module for all medium-duty truck brands?
Yes — we carry used transmission control module units for Isuzu, Ford, Chevrolet, GMC, Ram, and Mitsubishi Fuso medium-duty trucks, not just the Chevrolet Kodiak C4500.
Is this used Transmission Control Module tested before it ships?
Yes. Every transmission control module we sell is inspected and tested before it ships, so it works right the first time.
How do I order this Transmission Control Module?
Request a free quote above or call us. Share your VIN and we’ll confirm exact fitment, then call you back with a quote in about 30 seconds — if we can’t reach you, we’ll email it instead.
Do you offer a warranty on this Transmission Control Module?
Yes — used electronics like this transmission control module are backed by our warranty, a category most sellers exclude entirely. Exact terms are confirmed on your quote.
Do you ship this Transmission Control Module nationwide?
Yes — we ship to all 48 contiguous states with tracked delivery. Most parts arrive in 3–7 business days; engines, transmissions and axles ship freight and typically arrive in 5–10.
Is my truck’s TCM a separate module?
On Isuzu NPR/NQR/NRR (Aisin A465), GM Allison-equipped trucks and Ram 4500/5500 (Aisin AS69RC), yes — it’s a separate box. On many Ford TorqShift trucks the transmission strategy lives inside the PCM; tell us your truck and we’ll point you to the right part.
Will a used TCM fix limp mode?
If the codes are internal to the TCM, or a lost-communication code with good power and ground, yes. If the code is a solenoid, speed-sensor or pressure fault, the transmission itself needs attention — we stock those too.
Is a used electronic module covered by a warranty?
Yes. Electronics are covered under our warranty — a category most used-parts sellers refuse to warranty at all. Programming, where your truck needs it, is the buyer’s responsibility unless agreed on your quote.
