I have a 97 Chevy G2500 with 4.3 v6 automatic and when I put it in drive it will shift fine until it tries to go passed 3rd gear. After 3rd gear it just seems like it goes into neutral. It seems like it goes into 4th for a second but then it just revs up and never goes into 4th. It doesn't seem to slip in any of the other gears. If you have any help to offer please let me know your tips. Thank you.

what tranny do you have 4L60 or 4L80?
gm stated on 4L60/4L80 there is a replacement harness for the VCM because of a bad ground condition developing
also starting 1998 GM revised the shift solenoids, so if you got a 4L80 it's a possibility you would have to change solenoids 1-2 and 2-3
