Hello I got my trans rebuilt after it got burned up since the tv cable got disconnected. Now its all refreshed but I went non lock up since Its in a jeep and I want the less electrical as possible. But when I test drove it. It seams to do a weird kind of slip in 4th but when I shift it into 3rd it seams not too slip and go more in mph with the same amount of throttle. And after I test drove it on the highway it has trouble shifting into 2nd it does it after going high rpm then giving it a little less throttle (about 2800rpm its a diesel motor). I wanted to see if this is normal and want to get a 2nd opinion before going back to my trans guy. Well thanks in advance!
