Know the Signs
A transmission warns you before it fails. Here's what the common signs mean — and how urgently to act.
The engine revs but the vehicle hesitates or surges before it catches — often worn clutches or low fluid.
A pause before it goes into gear, or a hard clunk when it does — it isn't engaging cleanly.
A shake at light throttle is often a failing torque converter or contaminated fluid.
Bright red or brown spots mean a leak. Driving on low fluid lets the unit overheat fast.
A transmission fault code, or the vehicle locked into one low gear, needs a real scan.
A hot, acrid smell usually means overheated fluid breaking down. Pull over and call.
Not sure what you're dealing with? An honest diagnosis tells you what's really going on — no upsell, written estimate first.

What We Work On
Cars, trucks, and RVs — gas and diesel. If it shifts gears, we repair, service, rebuild, or replace it with a quality remanufactured unit.
Diagnosis, valve-body and solenoid work, and complete in-house repair for modern automatics across all makes and models.
Clutch replacement, hard-shift and grinding fixes, and full manual gearbox rebuilds.
Continuously variable transmissions diagnosed and repaired — with a dedicated Nissan & CVT deep dive in the guides below.
Heavy-duty diesel and Allison transmission repair built for work trucks, fleets, and RVs.
Domestic, Asian, and European — we work on the makes and models Denton drives every day.
When a repair won't do, we rebuild in-house to factory spec — or fit a quality remanufactured transmission when that's the better call for your vehicle. The rebuild guide walks through both.
Down to the Component
Most transmission trouble comes down to one component. Because we rebuild in-house and diagnose at the part level, we repair what's actually wrong instead of selling you a unit you don't need.
Shudder, stall, and lock-up problems traced and repaired at the source.
Erratic or harsh shifting fixed by the part causing it — not by guesswork.
Leaks stopped at the source — pan gaskets, output seals, and cooler lines — before low fluid takes out the unit.
Driveshafts, U-joints, and CV components — the connections that put your power to the ground.

Go Deeper
Before you authorize a rebuild, know what you're looking at. These are the questions we get asked most, answered straight.
Low fluid has a specific set of symptoms — and a fluid colour chart tells you more about the transmission's health than the level does.
Signs of Low Transmission FluidThere's a real decision framework here, and it turns on the housing, the parts supply and the mileage — not on which one sounds cheaper today.
Rebuild vs. Replace a TransmissionGood to Know
It depends on the failure. Often a single component — a torque converter, valve body, or solenoid — is the real problem, and a targeted repair costs far less than a full replacement. We diagnose first and tell you honestly which one you actually need.
It varies by vehicle and the type of failure, so we never quote blind. We diagnose the true cause and give you a clear written estimate before any work begins — no surprise charges.
