96 Suburban Transmission

[mistersuburban]

My 96 is a 1/2 ton four wheel drive. Very seldom use 4 wheel. The trans has been bulletproof, until now. It blew a fuse, located on the drivers side of the dashboard. It was replaced and was OK for a day. Then, it started off from a stop in what appeared to be 3rd gear. Had it examined again and fuse was good. So I have a possible wiring problem somewherre. All other underhood fuses are good. Anyone else have this problem. Help Appreciated. I suspect the trans is the 4L80.

Whether a 4L80 or 60, it's a 80e or 60e, electronic. You have to run a transmission scan to determine the problem.

Solenoids, which can be tested with the proper diagnostic tool.
