02 / The standard

Diagnose first.
Pull last.

Dean's public pledge is simple: a transmission does not come out unless it truly needs to. Most units are rebuilt or repaired right in the Spanish Fork shop.

  1. 01

    Listen & diagnose

    Start with the symptom, road-test when appropriate, then isolate the mechanical or electrical cause.

  2. 02

    Explain the options

    Understand the repair, alternatives and warranty before work moves forward.

  3. 03

    Repair with purpose

    Fix what is needed, document the coverage and get the vehicle moving again.

Honest work.

05 / Before you call

Good questions.
Straight answers.

Can I keep driving with a transmission leak?

Dean's recommends fixing leaks promptly. Losing fluid or pressure can turn a smaller repair into serious transmission damage.

Do you rebuild transmissions in-house?

Yes. The shop says most transmission rebuilds and repairs are completed on-site in Spanish Fork.

What vehicles and systems do you work on?

Automatic and manual transmissions, diesel and high-performance applications, 4×4 systems, transfer cases, clutches, differentials, driveshafts and related diagnostics.

Is towing available?

The current shop website advertises free local towing. Call first to confirm your vehicle and pickup location qualify.
