Our transmission kicks into second gear when our teuck gets hot. We replaced the transmission and computer but nothing it still does it. We basically had everything replaced except for the engine. Could it be a speed sensor that's the only thing not replaced or could it be something else. We have a 3/4 ton 2500 gmc suburban with a 454 in it.

No there's no warranty. When we got it they said it had warranty but after they did the work they said there's not one. What's a accumulator spring?
