Default 99 Grand Cherokee Shifting Problem

Hi All
New to this so bear with me. I have a 1999 Grand Cherokee 4.0 that has not had any transmission problems at all. Yesterday I stopped at a store and when I was leaving the transmission would not shift into second gear. I tried to manually shift it to help it along but didn't help, i also tried with and without the overdrive on, nothing. I can run it in drive 2, rpms at 3500, speed about 30mph thats how I got it home, i believe thats the limp mode.
It seems like its not even trying to shift into gear ???. fluid is full. I was told it might be the TCM, does anyone know where its located on my vehicle. Any help anybody
Thanks
Dennis

This will show you where it's located. Click the pic to enlarge. http://www.wjjeeps.com/modules.htm
Sounds like the TCM might need to be re-flashed by the dealer.
And Welcome to CF.
