Need some help in determining what's wrong. Going down interstate and big noise. Drive shaft is totally broken in two pieces, rear section is on the highway some ware. U-joint is still attached to differential. Front half is still in transmission. Transmission leaking fluid. Engine starts and runs good, park position locks drive line. I have not pulled drive shaft from trans yet. Need to clean off transmission to see where leak is coming from.
Did transmission lock-up someway or did u-joint lock, something locked to cause the split driveshaft and u-joint damage.
Where do I go from here? Might have to take it to shop.
