Automatic transmission

Asked by Gabe Aug 08, 2020 at 02:17 PM about the 2002 Chevrolet Silverado 1500 LS Extended Cab 4WD

Question type: Maintenance & Repair

So I'm having a problem with my 2002 Chevy Silverado not
shifting properly.   When accelerating to 30mph, it's still
running a 3k rpm's.  I have to let off the accelerator, re apply
and then it will shift.  After getting up to 45 and up to 65,
the rpm's climb  to about 4k to 6k rpm's.   I've replaced both
knock sensors which was the original issue.  Now it's still
operating at the same copacity.  What else could the
problem be?  I've changed the transmission fluid amd filter.   
A friend of mine hooked it up to his computer and he said
it's running fine.

Are the engine and or transmission mounts cracked and or worn. A classic symptom is reving up and shifting once you take your foot off the accelerator.
