thanks, will have those checked out....At that point, you gotta have a pinched coolant line or very clogged trans cooler.

When the local shop rebuilt the '700 in my '88 K1500 a couple of years ago, part of their service is to connect a solvent-filled flush machine to the trans cooler tubes. The "machine" flushes the tubes and cooler while the trans is on the work-bench. After an hour or so, the machine turns on a green light if the restriction level is OK, or turns on a red light if the cooler system has excess restriction.At that point, you gotta have a pinched coolant line or very clogged trans cooler.
You would think so, right?When the local shop rebuilt the '700 in my '88 K1500 a couple of years ago, part of their service is to connect a solvent-filled flush machine to the trans cooler tubes.

I would have thought that something similar would be in every trans shop in the country. Maybe I'm wrong.

Trans lines are checking out okay, I'll ask them to check out the ground wires...GM had a bulletin on faulty computer grounds that caused trans problems. Add a wire, move a couple of other wires to different points in the plastic connector...
...but I thought that was '96 only.
Yes, but only for a 1996 built before March of 96.GM had a bulletin on faulty computer grounds that caused trans problems. Add a wire, move a couple of other wires to different points in the plastic connector...

Yes there is a GM Service Bulletin 00-07-30-026 that addresses the faulty ground issue for 1996 C/K models. Transmission failure...
