89 B2, 4x4, 3.9, a4ld, previous owner said the trans has 2500 miles since rebuild.
problems are as follows:
start it up, put it in reverse, after about 3 seconds it engages
put it in OD, gas it, and i get almost a grinding sound, like a bad cv axle, but its in 2wd.
after it shifts to 2nd, its fine.
then once i get to a cruising speed (45-50mph) in 4th gear, if i give it gas to merge or pass someone, it wont downshift to 3rd.
if you put it in drive, not OD, it runs and shifts fine.
side note, dont know if the trans problem is related, had a bad coolant leak from a hose, it overheated a bit, so i changed the hose, then noticed the water pump was leaking, so im replacing that. i know there is a trans cooler on it, would it cause this to happen?
