I have a 95 dodge ram 1500 4wd. Its an auto trans. Here is the question. It started yesterday after I drove it up the interstate. Well when I go to take off from a dead stop it will move slow and the rpms jump up to about 2200 before it starts to move. Now when I pull the shifter down to 2nd it takes off a little quicker. It will not shift from 1st to drive it stays in drive and it won't shift into over drive eiter . I just replace the trans about 3months ago and it seems fine. Now once I put the truck in park it jumps a little forward. It will catch and back up great but don't have no power to turn the tires over in drive unless u put it in 1st but u can tell it dont shift expect from 2nd to 3rd. What could it be?
