Transmission Fluid and Filter Service
Transmission Repair — Cheyenne, WY
Transmission fluid does everything in an automatic — it lubricates, cools, and actually transmits the power — and it wears out, especially in trucks that tow. Heat is the killer: fluid that's spent summers dragging a trailer up I-80 grades breaks down, and worn fluid takes clutches and valve bodies with it.
TDC services transmissions with the correct fluid specification for your unit — modern transmissions are unforgiving about fluid type — plus filter and pan gasket, with a look at what's in the pan. A little friction material is normal; glitter is a conversation. 'Lifetime fluid' means the lifetime of the fluid, not the truck; if you tow, service it.
What's Included
- Correct fluid spec — not universal 'close enough' fluid
- Filter and pan gasket replacement
- Pan inspection: honest read on wear evidence
- Intervals adjusted for towing and heavy use
- Upgraded pans and coolers available for tow rigs
Transmission Problems, Diagnosed Honestly
- Check the basics first
Fluid level, condition and smell, plus a scan for codes — a surprising number of 'dying transmissions' are none of the above.
- Road test and data
Shift points, slip, flare and hunt get verified on the road with live data watching line pressure and converter behavior.
- Diagnose before teardown
Electrical, hydraulic or mechanical gets determined before anyone talks rebuild money.
- Fix at the right level
Service, targeted repair, replacement or performance build — matched to the truck and your plans for it.
