My work truck is 12 Ram 1500 ST with V6. It's the 4 speed auto tranny and often when put into reverse it'll shudder like it's slipping. Most noticable when reversing up an incline but will do it on the flat as well. Anyone else had a similar issue and what was the resolve? I'm taking it in tomorrow but thought I'd check with you guys to see if anyone else had a similar problem.
