5 Signs of a Semi Truck Transmission Problem

Minor transmission issues can quickly turn into major problems that require expensive repairs. At the very first indication of transmission trouble in your semi truck, you'll want to bring your rig to a reputable mechanic who specializes in commercial truck repair. Here's a look at five signs that you need semi truck transmission repair.

Popping Out of Gear

You will generally notice this problem in two gears, one on the low side and the same hole on the high side. This is usually caused by a worn siding clutch in the main box.

Transmission Fluid Leak

For the proper lubrication of your transmission's moving parts, it's important to always drive with the right amount of clean fluid. It's good practice to periodically scan over the ground where your truck has been parked and check for signs of fluid leaks. If it appears that transmission fluid is leaking, you'll want to be proactive about getting the leak repaired so that you don't risk more serious problems. A common leak source in vocational trucks is at the PTO.

Difficult to Get into Gear

It shouldn't take numerous tries to simply get into gear. If you notice when you try to put the truck in gear that it grinds, then you may be due for a clutch adjustment.

Grinding Noises

Grinding sounds that come from your truck's transmission could be emerging because of low transmission fluid. These noises could also be caused by the wrong ride height adjustment. Proper ride height sets the pinion angles in your driveline, which is very important. This noise is usually heard in high gear.

Low Power while Accelerating

For smooth and consistent acceleration, you need a healthy transmission. If you're noticing acceleration issues, it'll be worth having a mechanic inspect the matter.
