Transmission Repair in Cheyenne, Wyoming
Honesty & Quality
Transmission trouble makes people fear the worst, but the honest truth is that many 'transmission problems' are fixable for far less than a rebuild — a leak, a solenoid, a fluid service, or an electrical fault. That's why every transmission job at TDC starts with diagnosis, not a teardown quote.
The shop covers the full range: fluid and filter services, leak repair, transfer case work, remove-and-replace jobs, and built performance transmissions for diesels making more power than stock ever intended. If you tow heavy, auxiliary coolers and upgraded pans that keep fluid temperatures in check are some of the smartest money you can spend.
Transmission Services
Transmission Diagnostics
Slipping, hard or delayed shifts, flaring between gears, shuddering at lockup, or a sudden limp-mode trip home — transmission symptoms are scary, but the cause is often electrical or hydraulic rather than mechanical.
Learn more →Transmission Service
Transmission fluid does everything in an automatic — it lubricates, cools, and actually transmits the power — and it wears out, especially in trucks that tow.
Learn more →Transmission Leak Repair
A transmission leak is the cheapest transmission problem you'll ever fix — right up until it isn't.
Learn more →Transfer Case Service & Repair
The transfer case is what makes your 4x4 a 4x4 — and around here it actually gets used, which means fluid services matter and wear eventually shows up as growls, whines, leaks from the output seals, or four-wheel drive that won't engage when the snow is already falling..
Learn more →Transmission Replacement
When diagnosis shows the transmission really is finished — burned clutches, a wiped pump, hard parts in the pan — TDC handles the full remove-and-replace: sourcing a quality reman or used unit, replacing the converter and cooler flushing (skipping that step is how replacement transmissions die young), and doing the install with driveline angles and torque specs respected..
Learn more →Performance Diesel Transmissions
Stock diesel transmissions were engineered for stock power, and the moment a tuner adds a few hundred foot-pounds, the factory clutches and converter become the weak link — slipping, overheating, and eventually failing, usually while towing.

Heat is the number one killer of automatic transmissions, and towing is the number one source of heat.

Fluid level, condition and smell, plus a scan for codes — a surprising number of 'dying transmissions' are none of the above.

- Diagnose before teardown
Electrical, hydraulic or mechanical gets determined before anyone talks rebuild money.

Service, targeted repair, replacement or performance build — matched to the truck and your plans for it.
