why does my 1998 isuzu hombre shift hard after it warms up?

Question

4X4 4.3

Answer 1

Excessive throttle pressure can cause this. Input to the trans is controlled by the computer, but influenced by speed sensors and throttle position sensors. It could be in the valve body as well so you will want to get someone with proper equipment to check it. If you get an expensive estimate, get a second opinion.

Answer 2

when was the last time you changed the oil in the tranny or the transfer case

Answer 3

have you chacked the fluids if so when is the last time they were changed
