i have a 93 cherokee sport 4.0ho automatic trans. the trans is shifting high @45 n sometimes its shiftin @2grand n hits overdrive @ 35mph, its deff gona blow soon ne sugestions could it b a sensor or computer not letting it shift. i got no power @ all. i dont know **** about transmissions either, i have a trans out of a 95 cherokee that my buddie drove into the ocean n hydrolocked the motor, idk if its good to swap in but i guess im gona have try it.

also yesterday my check engine light came on i drove the truck for 30mins around town then shut it off, didnt start just cranking over, checked all fuses n relays they were fine till i smacked the fuel pump relay a few times it started right up, replaced the relay now it just cranks n u got to floor the gas to start it, when u floor it whe driving it breaks up n sumtimes backfires. did a tune up 3months ago, possibly a fuel issue? idk fml

could be your throttle position sensor, for the high shifting points
