My 98 jeep grand Cherokee limited 4.0L zj automatic transmission 42re will not shift, acts like it's in 1st gear all the time! The rpms run high but the jeep won't accelerate! I've replaced the governor pressure sensor & solenoid & both 02 sensors & the check engine light came on again for the same things.. so do you have to reset your jeeps ecu after replacing sensors? If so how! & my other question is could it be my transmission speed sensor without a check engine light on
What makes this problem better or worse?
It's worse when trying to accelerate or on hills
