    Default 1999 GMC Jimmy Transmission Problem

    Hi Everyone! My name is Matt and I have an issue that just happened this morning. I have a 1999 GMC Jimmy that will not shift into reverse and it also has to rev very high to shift from 1st into 2nd. I was able to slowly get home after dropping my wife off at work. We currently have one vehicle and it is very important that I figure out what is happening. I have read a couple of the posts on this site and it appears that others have had this issue as well. I am curious if anyone has any advice as to where I should start looking after checking the fluids, which are full, and adding some JB tranny helper. Any advice that anyone has would be greatly appreciated, thank you in advance.
