Transmission slipping when hot

I assume the temp gage is for the engine and dosn't that seem a little high? Maybe engine is derated because of heat? But how does the fluid look? burnt? change it much? On a temp note...fan clutch working properly?

I have a 1985 S10 Blazer 4 wheel drive 2.8 engine

and it runs great as long as the temperature gauge is below 210

but as soon as I get stuck in traffic or on really hot hot days it seems like I'm not able to accelerate as fast as I normally can, as if the trany is slipping or maybe just not going into 3rd gear........

is this a sign of the fluid just becoming too hot or is this a sign of a sticky valve in the trany.....

any ideas ........

like I said the transmission works fine as long as the temperature is cool....... I have an overdrive automatic transmission too......

Your transmission needs to be rebuilt.
