Out of town with a 4l60e issue

[Minime168]

So im 200 miles from home for a week. I drove the truck down here. 1992 full size blazer with 2005 5.3 swap and 4l60e. Truck ran fine all the way down. now down here I pressed the gas to pass someone and it shifted into second. Probably only reved to 4000 rpms tops. Then when I come to the next stoplight, its like its not locking up? It revs to about 2200 before the truck even starts rolling. Still shifts fine, and once in third gear, it catches and runs okay. Reverse also runs okay. Whats the deal? Thought it was low tranny fluid but it's not.

Any help appreciated! Im stuck here until this is fixed!

Servo? Bad seal can cause it to slip. Hope u fig it out man

Could it be antifreeze in the transmission because of a radiator leak? The truck has also sprung a little antifreeze leak...

So its leaking thru tranny cooler somehow? Into the fluid? Makes perfect sense. Could have completely broke down the fluid. Kinda like the slipping you get while have even half a quart over full.

In the saab the condenser rubbed hole into my tranny cooler and they combined and was in a tight spot. Had to replace them both. And build a better mount for the tranny cooler to seperate it more.

Well Im at a loss. Its not the TPS, i dont think its the fluids mixing. Whats the deal? now all the gears are acting up.
