Question about 1996 Jeep Cherokee Country
This is for a 1989 Jeep Cherokee pioneer with a 4.0 4wd automatic tranny.
It just started not wanting to go into gear and you can hear the engine rev-ing and you can left off the gas pedal and back down and it will go most of the time into gear. Once you get it into a higher gear it will work ok until your rpms back off then it wont pick up the high gear again until you rev your engine up to catch it.
Before this and I dont know if there is any relation, but the vehicle was running sluggish, I thought it was the fuel pump and replaced it, but then it backfires sometimes...not all the time, just when you think it isnt going to anymore..you might drive anywhere from 10 to 50 miles before it happens again. Most of the time when it backfired it was when I had left off the gas at higher speeds and then it would give you a nice hello pop.
Thanks for any suggestions.
I'd run a code check first, just to give you an idea if anything is leaving footprints in there. Transmission performance is somewhat related to engine performance but if you haven't serviced trans in a long time, do it.(if there is a lot of debris in there it may be time for a rebuild) Backfiring may be caused by an air leak in the exhaust manifold, allowing gasses in front of the cat to re-ignite. But, this could be caused by other things as well...that's why code read is important.
