i put my 2000 grand cherokee in reverse and nothing happens. ill hit the gas and the wheels dont spin. i put it in neutral and it goes forward and drive 1st and 2nd all go forward. can anyone tell me what is going on with the tranny here or could it be something else other than the tranny.

Have you checked your transmission fluid?

Like he said, check your fluid level, that's always the first thing to do. Without knowing more specifics, other possibilities could include a linkage problem, or a problem with the reverse band inside. Do you have any hesitation in the forward gears? If you pull it all the way back into 1, does it grab right away and hold it until you shift to 2, and is there any hesitation? If you are driving slowly ~5mph, pull it back into 1 and then put it into 2, and just idle along going back and forth, this should tell you if you have clutch problems rather than just a bad band. And if you have hesitation everywhere and your fluid level is ok, it may just be a plugged trans filter. These are just common tranny diagnosis things, some other people may have more specific advice.

ok thanks guys it does hesitate in first but my planetary gears are messed up for a few months now.

the tranny fluid is fine.

I'm assuming you mean the planetary gears in the tranny, if so, then I'm guessing it's about time for you to spend some time in a shop or be looking for a replacement. If the rear planetary is on the way out, the rear band will go as well, which could cause the loss of reverse and overall trboule engaging the proper clutches, unless I'm looking at my charts wrong. I hate transmissions.

ok thanks guys. i got it checked at aamco today and they checked the fluid which was fine and they said it wasn't throwing any error codes and it wasnt anything electronic it was something internal.

Hate to be the bearer of bad news, but losing reverse gear is usually a good indication that you need a rebuild. Which tranny do you have? Engine? How many miles? Does the tranny slip or grind at all in Drive?

i have a 4 liter and it does slip and grind for several months now. not sure which tranny it is.
