Warning Signs of Transmission Failure
If your vehicle exhibits any of these warning signs, get in touch with our Missoula shop before minor symptoms develop into severe mechanical failures.
Slipping Gears
If your engine revs up high but your speed lags—especially noticeable when hauling outdoor gear up towards Marshall Mountain—or the car slips out of gear while driving, your transmission fluid is low or the internal clutches are worn out.
Rough or Hard Shifting
Feeling a hard clunk when changing gears or hearing a metallic grind when shifting indicates low fluid pressure, solenoid issues, or synchronization failures.
Fluid Leaks
A puddle of red or brown fluid under your car is a clear warning sign. Low fluid causes rapid heat buildup that can burn out a transmission in minutes.
Delay in Engagement
If you shift into Drive or Reverse and the transmission takes several seconds to catch and move, your internal hydraulic seals or pumps are failing.
Our Transmission & Drivetrain Services
Our mechanics follow factory service procedures, using professional diagnostic tools and premium replacement parts to make sure your repair is done right.
Automatic & Manual Repair
Transmissions use complex gears and clutches to transfer engine power to the wheels. In automatics, we troubleshoot shifting delays, slipping gears, and failing hydraulic solenoids. In manual vehicles, we replace worn clutches, pressure plates, and throwout bearings to restore smooth gear shifting and prevent pedal slippage.
Transmission Fluid Flushes
Transmission fluid acts as both a lubricant and a hydraulic fluid that shifts gears. Heat degrades this fluid over time—especially when towing trailers up the steep grade on Highway 93 towards Lolo Pass—turning it brown and causing clutches to slip. We exchange old, burnt fluid with fresh synthetic fluid to keep parts cool.
Complete Drivetrain Services
We service and replace transfer cases, front and rear differentials, worn CV axles, driveshafts, U-joints, and complete transmission assemblies. This restores clean, reliable power delivery to the wheels and eliminates clunking noises or grinding when you accelerate or engage four-wheel drive for winter driving in Blue Mountain Recreation Area.
