Tranny Stops When Eng Warms Up
 

HI I have a 1997 Blazer with the 4.3. The Tranny work great when I start it untill it warms up and then the tranny just gose in to nurtral and will not do any thing. :icon_hyper:

There are quite a few things that can cause a slipping trans. Have a read through the Tech Article (DIY) section for the 4L60E common problems thread and see if any of those symptoms sound similar to yours.
