Transmission Service and Repair in Arvada, CO
Hard shifts, slipping gears, grinding noises — a transmission that's acting up doesn't fix itself. We service both manual and automatic transmissions, from basic fluid changes to full rebuilds. If your car isn't shifting the way it should, bring it in before the damage spreads.
What's Involved
Transmission service depends on the type and the problem. A fluid change is maintenance. A rebuild is surgery. We'll tell you which one you need.
- Manual transmission fluid change (Motul, Red Line, OEM fluids)
- Automatic transmission fluid and filter service
- Transfer case and differential fluid service (AWD and 4WD)
- Transmission diagnostics — scan tool data, road test, visual inspection
- Synchro wear assessment on manual boxes
- Valve body and solenoid service on automatics
- Full transmission rebuild or replacement
Manual transmissions are common in our shop — WRX, STI, BRZ, Civic Si, Focus ST, Mustang GT. We know what good shift feel is supposed to be, and we know when worn synchros or low fluid are the problem. On automatics, we'll look at the fluid condition, scan for transmission codes, and check line pressures if the issue calls for it.
Signs You Need Transmission Service
- Hard, delayed, or jerky shifts (automatic)
- Grinding when shifting into gear (manual)
- Transmission slips — RPMs flare but the car doesn't accelerate
- Whining or humming noise that changes with speed, not engine RPM
- Burning smell from underneath or transmission fluid leak
Why It Matters
Transmission fluid breaks down with heat and age. Worn fluid loses its friction properties in automatics and its ability to protect gear teeth in manuals. A $150-$300 fluid service every 30,000-60,000 miles is basic insurance against a $3,000-$6,000 transmission replacement.
On manual transmissions, grinding going into a specific gear usually means a worn synchro. Caught early, the fix might be fluid and driving habit changes. Let it go and the synchro ring disintegrates, sending metal fragments through the rest of the gearbox.
