Transmission Repair in Missoula, MT
Transmission trouble makes people nervous, and for good reason. It's also one of the areas where careful diagnosis matters most, because not every shifting complaint means the transmission has to come out.
Low fluid, a bad sensor, a wiring fault, or a software issue can all make a healthy transmission act up. We rule those out before talking about major work, and we show you what we found either way.
Signs of transmission trouble
- Slipping, where engine speed climbs but the vehicle doesn't pick up speed.
- Harsh, delayed, or hunting shifts.
- A pause before it engages when you shift into drive or reverse.
- A shudder at steady speed, often felt on the highway.
- Whining, humming, or clunking when it changes gears.
- Red or brown fluid under the vehicle, or a burnt smell.
- A transmission or check engine light, or the vehicle stuck in one gear.
What we check
We start with the fluid. Level and condition tell us a lot: low fluid points to a leak, and dark or burnt smelling fluid can point to overheating or internal wear. Then we scan for stored codes, which often name a sensor, solenoid, or circuit.
We road test to feel what you're describing and when it happens, whether that's cold, hot, under load, or at a certain speed. We also check the things outside the transmission that can imitate internal problems: mounts, shift linkage or cables, cooler lines, wiring, and engine misfires that feel like a bad shift.
Manual transmissions get the same approach, starting with the clutch, hydraulics, and linkage before assuming the gearbox itself is the issue.
When it's a smaller fix, you'll know. When it's genuinely a major repair, we explain what we found and the options honestly so you can decide what makes sense for the vehicle.
What can wait and what can't
Don't put these off
- Slipping or a loss of drive
- A leak that's dropping the fluid level
- Burnt smelling fluid along with shifting problems
- The vehicle stuck in one gear
Often fine to wait
- A slightly firm shift that hasn't changed over time, once we've checked codes and fluid
- Fluid that is due for service but shows no signs of trouble
- A small seep at a seal that isn't lowering the level
Driving on a slipping transmission usually turns a smaller repair into a bigger one, so if it's slipping, the sooner the better.
Towing, hills, and transmissions
Heat is what wears out automatic transmissions. Towing a trailer, hauling a load up a grade, and long stretches of stop and go all add strain. If you tow or haul regularly, fluid condition is worth checking more often than the standard interval.
We work on automatic and manual transmissions in cars, trucks, and SUVs, foreign and domestic. On four wheel drive vehicles we look at the transfer case too, since its problems can feel a lot like a transmission problem from the driver seat.
Transmission Repair questions
Do I need a new transmission?
Not necessarily. Many shifting problems come from low fluid, sensors, solenoids, wiring, or software, and those are much smaller repairs. We diagnose before recommending anything major.
Should I get my transmission fluid changed?
Follow your manufacturer's service schedule. Fresh fluid helps a healthy transmission stay that way, especially if you tow. We'll look at the fluid and tell you honestly whether it's due.
Can I keep driving if my transmission is slipping?
It's best not to. Slipping creates heat and wear quickly, and it can leave you stranded. Have it checked as soon as you can.
How long does a transmission repair take?
It depends on what it needs. A sensor or an external repair is a very different job than internal work. Once we've diagnosed it, we'll give you an honest idea of timing.
We show you before we fix it
Before any work starts, we walk you into the shop and show you what we found. If something can wait, we'll tell you.
