First of all thanks for a great forum. my 97 dodge ram 5.2 auto 2wd has a trans problem like all of them. It slips in O/D and on longer trips with the O/D off it slips in 3rd. we are pretty sure that the trans is fried. we are having trouble finding a replacement. it would help to know if we could use the tailshaft from a 2wd on a 4wd trans as long as its a 46RE? does anyone have any input or tips on this? thanks in advance for your help.
