My truck is a 94 Chevrolet k5 blazer. My question is: is it normal for the transmission to have delayed shifting when the engines hot. Shifts normal when the engine temp is around 170 but after sitting in hot weather with AC the engine can get around 210 and thats when I notice the delayed shifting. After moving the vehicle temp goes back down to normal and shifting returns to normal as well. I have checked transmission fluid and was at correct level. I guess what my main questions are: is this normal?and if not what could be causing it.
