2001 Chevy Tahoe shifting issue
My Tahoe revs in 3rd gear. I've changed
transmission fluid, filter and solenoids A&B. No
check engine light. What could be the issue?
It might be wear/leaks in the valve body caused by defective seals & rings. It could be a defect in the PCM or the TCM, or if your speedometer also has issues, it could be a bad VSS. Or it might not be in the transmission itself, but is engine related; like a problem with the TPS or the MAP/MAF sensors. Could even be a bad alternator failing to supply enough current for the systems to run properly.
Thank you so much. I will look into these since there is no check engine light on.
May be a toque converter problem
Thanks, I will check that out as well.
