Transmission

Asked by Guru9GR7N Aug 01, 2017 at 07:11 PM about the 1995 Chevrolet Suburban C1500 RWD

Question type: Maintenance & Repair

On my Suburban 1500 it was started
overheating and then the tranny started
slipping and now the transmission
doesn't work after overheating about 5
times I had to readjust my timing
because of the overheating and there's
last time when the transmission
stopped working it had no training fluid
in it so I let it cool down and I put new
tranny fluid in it and I had to drive it like
a stick and then I just lost all gears all
together and about 300 degrees how
can I fix this

Started overheating? The transmission or the motor? 300 unreal hot for either of them. Was this under a heavy load or going up and down extremely hilly country? I know on my 2003 Tahoe, I had some intake manifold/vacuum issues and I thought I might have lost my transmission, but I fixed the vacuum leak and it started shifting great again. That said, it was in extreme cold (-5 degrees F type weather). One thing I do know is if your clutches actually slipped, your transmission needs a rebuild. You might get some life by dumping in some additives, but it will just be at the cost of other parts within the transmission. If you do decide to have it replaced or rebuilt, make sure they (or you) blow out or replace the transmission cooler, radiator, and cooling lines. The transmission cooling system can get shavings and debris in them that will impact the new/rebuild transmission. Sorry for your issues.
