Shifting Issues

[Wdpatterson]

New to the Forum here, just picked up this truck for almost nothing. I’m having some shifting issues. It’s a 2000 Silverado 1500 LS, 5.3L 4x4 z71. I have the SES light for random Miss fires, I already ordered coils, plugs and wires. Shifts from 1 to 2, when it hit 3, RPMs run straight up, then it’ll cruise about 60 at 4K RPM. Video I took of it.

Trans is toast.  Typical 4L60 problem. Get it rebuilt.

Probably is the tranny but maybe check a few basics first ?

 

1: Tansmission fluid level & condition.

2: Any stored or pending trouble codes ?

3: Maybe double check the transmission cable adjustment to insure that the transmission is fully seated in the drive position. (You can get some wear in the place that the cable connects to the transmission.)
