On a 2001 dodge intrepid with a 2.7, whether you put it into drive or reverse it does nothing...this started when drivin on day it went into a limp mode...got it home and parked and when i later tried to move it there was no response from the tranny...

Limp mode as in computer limp in mode?check the trans fluid is it dark looking?, Need more info. Did you have the trans fluid changed recently? The reason i ask is when you change the trans fluid way after its do the new trans fluid is detergent type and fresh fluid can put the transmission in shock(Trans Shock). This can wipe out a transmission in 5 miles or so seen it too many times. Let me know how it goes. Lee
