My beloved pickup, Helga, is making some transmission noises these days that are gradually getting worse. She’s a 4x4 and has about 182k miles, which is pretty young for a Tacoma. The transmission fluid was changed about 10k miles ago, as well as the clutch fluid and both diff fluids. This is the scenario in which she starts grinding:
-in any gear
-clutch pedal pressed
-truck is rolling
-grind is definitely related to rolling speed, not RPM
-sometimes, it doesn’t happen when clutch pedal is pressed, but does happen when I downshift. Stops when I let off the clutch.
-I don’t ever notice grinding when I’m shifting up the gears in acceleration, except sometimes if I keep the clutch pedal pressed with trans in gear for an extended period of time (for a shift, like more than a couple seconds).
I’m not having any problems with shifting or popping out of gear, etc. Other than the grind, the transmission seems to be operating just fine. Help me nurse Helga back to health. Thanks!
