Transmission Replacement
Light- & Medium-Duty
A transmission is one of the most expensive systems on your truck — and one you can’t afford to have installed wrong. Our certified technicians handle transmission replacement for light- and medium-duty vehicles with experience customers can trust.
Quick Answer
Transmission replacement is typically needed after an accident, years without regular maintenance, or hard driving that wears components beyond repair. Truck City Service’s certified technicians install replacement transmissions on light- and medium-duty trucks to factory standards.
This Is Not a Job for the First Shop You Find

A transmission replacement is expensive and will affect your vehicle’s performance for the rest of its life. You want technicians who are certified and have done this work on vehicles like yours before — not a first attempt.
The cheapest transmission quote is rarely the cheapest transmission repair.
“Proactive transmission service is what prevents most replacements in the first place. When we do see a full failure, it’s usually years of deferred maintenance or hard use catching up.”
