A heavy-duty truck’s transmission works to help you control your speed as well as maintain efficiency. You’ll need to pay attention to the fluid level in the transmission; if it’s low, this can lead to a complete failure of the engine and drivetrain.
The clutches are used to connect the transmission to the engine, and they are usually disc-shaped plates that are pressed against one another with springs behind them. You’ll need to replace your transmission or clutches if they hit each other hard enough to cause damage, which can happen if your truck’s clutch is worn out.
There are certain telltale signs that something is wrong with your transmission or clutches. For example, if your truck changes gears on its own or you feel a shudder when the transmission shifts, this could indicate that there’s something wrong with your clutches. You’ll also know you have faulty clutches if they make loud noises every time you press down the gas pedal.
Mileage recommendation: 100,000 miles for clutches
Generally speaking, there are two main solutions to transmission problems. The first would be to flush out the old fluid and replace it with new, synthetic antifreeze. This will help your engine lubricate your transmission properly and also ensure that all moving parts work as smoothly as they should.
If that doesn’t work, then it’s time to replace the transmission fluid lines, fittings, and filters. This is a harder job because you have to take apart your truck engine, so a professional mechanic can only tackle it.
Another option is to replace your transmission entirely if it fails or you notice problems like leaking fluids or a lack of pressure when applying the gas pedal. This will be more costly than flushing out the old fluid, but it also comes with an extended warranty and is easier to claim on your insurance policy over time.
If the problem is with the clutch, you’ll need to replace it or have it repaired. Conversely, if your transmission has problems, but your clutches are still intact, the problem is likely caused by a lack of fluid in the transmission pan.
