Ok I have a 97dr a4 and it does not go into reverse or neutral like it's liked but will go into every other gear I've.heard cleaning the tcm harness changing the tcm and the tms but it sounds like it wants to go in gear but can't when put in reverse it don't jump or lock it just sounds like a floating gear. So do you think it's the tranny? Or something with the awd it the switch and.control unit? Thanks
