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

  1. 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.

  2. Road test and data

    Shift points, slip, flare and hunt get verified on the road with live data watching line pressure and converter behavior.

  3. Diagnose before teardown

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

  4. Fix at the right level

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

Honest rates: gas $125/hr · diesel $135/hr, with findings and an estimate before repair. Call (307) 996-0980 to talk it through with Trevor directly.
