Maintain It. Or Rebuild It.

Transmissions fail two ways. Through neglect that proper service could have prevented. Or through internal wear that no service will reverse. The first one we can usually fix. The second one needs to come apart.

Service & Maintenance

Service That Actually Helps

  • Fluid sample, condition check, and drain-and-refill service
  • Filter and pan gasket replacement on applicable units
  • TCM scan, adapt clear, and shift relearn after service
  • External leak repair on pan, lines, and cooler fittings
  • Solenoid pack and valve body service for shift faults
  • Cooler line flush and inline filter installation
  • Manual transmission fluid service and synchro inspection
Rebuild & Replace

When Internals Are Done

  • Full internal teardown and documented condition report
  • Clutch packs, bands, bearings, and bushings replaced
  • Hard part inspection on drums, planetaries, and shafts
  • Torque converter remanufacture or replacement
  • Manual transmission clutch, pressure plate, and flywheel work
  • Bench break-in and pressure test before installation
  • Road test under load and TCM sign-off before delivery

Scan First. Quote Honest.

Every transmission job at Chris’s Diesel Service starts the same way. Scan the TCM, sample the fluid, road test under load, and tell you the truth about service versus rebuild before any work begins.

  1. 01

    Scan and Sample

    TCM scan for stored and pending codes. Fluid sampled and inspected for burnt smell, clutch material, or metal. Adapt values reviewed.

  2. 02

    Road Test Under Load

    Shift behavior tested on real roads, not the lift. Live data captured under acceleration, deceleration, and steady cruise. Findings written down.

  3. 03

    Honest Quote

    Service or rebuild scope on paper, parts and labor itemized, timeline included. We tell you if a service will actually help or only delay the rebuild.

  4. 04

    Build and Verify

    Work performed in-house. Bench break-in on rebuilds. Final road test, TCM relearn, and sign-off from Chris before the vehicle is released.

The Standard. Every Transmission.

A transmission is only as good as the build behind it. Below is what every transmission job at our Midland shop is held to before the vehicle leaves the bay.

  • OEM First OEM friction materials and hard parts where they exist. Best available alternates where they do not. Quote shows which is which.
  • In-House Rebuilds done in our Midland shop. Not outsourced. Not sold as a remanufactured exchange. Built and signed off by the person who knows it.
  • Both Types Automatic, manual, dual-clutch, and transfer cases on passenger vehicles. We do not refer transmission work out. We do it here.
  • Sign-Off Bench pressure test on rebuilds. Real road test under load. Personal sign-off from Chris on every transmission that leaves the shop.

Common Questions

How do I know if my transmission needs service or a rebuild?
Slipping under load, harsh or delayed shifts, burnt-smelling fluid, or fault codes from the TCM usually mean internal damage. Service can save a transmission that has only been neglected. Rebuild or replace is the answer once internals are worn. We scan, sample the fluid, and road test under load before quoting.
Do you service both automatic and manual transmissions?
Yes. We work on automatic transmissions, manual transmissions, dual-clutch units, and transfer cases on passenger vehicles at our Midland shop. Fluid service, clutch and flywheel work, hydraulic repair, sensor and solenoid replacement, and full internal rebuilds are all done in-house.
How long does a transmission rebuild take in Midland, TX?
Most passenger transmission rebuilds run four to eight business days at our Midland shop, depending on the unit and parts availability. We give you a written timeline before any work starts and update it if parts back-order changes the schedule.
Can a transmission fluid flush damage my transmission?
A proper drain and refill is safe. High-pressure flushes on a neglected transmission can dislodge debris and accelerate failure. We sample fluid first, decide which service is appropriate for the condition, and tell you honestly if a service will help or only delay the inevitable.
Do you use OEM parts for transmission rebuilds?
Yes. OEM internals and friction materials where they exist, and the best available alternates where they do not. Quote shows exactly which parts are OEM and which are alternates. We do not cut corners on hard parts, clutches, or sealing components.
