“He was so honest. We thought the transmission was broken, and he could have easily taken advantage of us.”
A traveler credited Tyson with finding parts and getting a damaged diesel truck back on the road before a holiday weekend.
A Spanish Fork family remembered a loose shift cable being fixed without charge instead of being sold a major repair.
An Orem customer described a referral, a smaller electronic repair, and a car that was still working well more than a year later.

Can I keep driving with a transmission leak?

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.
