Mopar A833 - 70 Duster

Holy crap.....I called the shop this morning that rebuilt my trans and the owner was stumped. He was asking my if I tried this and that and I was like of course. I'm not a dumbass......Anyways I watch the video about 3 or 4 times and during my lunch break since I am still working from home I got under the car. Drained my new gear oil and loosened the side cover bolts. Put my adjustable wrench on the reverse selector and it moves freely now and goes into reverse. I tightened down the side cover slowly and in a crossing pattern tested reverse after every bolt and its fixed. So happy I don't have to get a tow or take the trans back out. The shop said he would call me back which he hasn't yet. Thanks a lot of the info Mike. Saved me. Stay safe and healthy.
Good to hear! I thought may-be it was the side cover. That training video/slide show might be old school but it taught me a lot. Rock on!
