Default fairly new built up transmission popped...what could it be??

On the way too work yesterday morning accelerating very lightly, I heard a clunk noise and the car kinda jarred almost like I got bumped in the rear. I pulled over immediately and turned it off. My first thought were the rear end. I got it towed to the shop who built the trans(very respected guy around here)

The car wouldnt roll backwards off the tow truck in neutral, but it would roll forwards?? we started it up after it was off the truck and NONE of the gears seemed to work at all. what could it possibly be? he wont find out til early next week and its driving me nuts.

we did open the rear end up and all was fine there. Im really hoping I dont need to send my converter out for a cut and clean. lol Im also hoping this doesnt cost me much because the trans is maybe 6 months old and 6k miles with only about 10 track passes.

Not a tranny expert, but when you heard the clunk, was it in the middle of a shift?

Similar situation happen to me with my rebuilt tranny, except we were making some tuning wot passes, then it fell on it's face and lost first and reverse gears. The input drum shaft w/snap rings in my tranny had broken.

On another occasion similar to yours, I was making a wot pass, then heard a pop. After a short distance, the rearend locked up on me. Come to find the ring gear bolts had backed out. I know you said the rearend was checked, but are you sure you didn't see any bolts lodged up between the carrier and ring gear?

If its a trans failure you need to have the converter cut/cleaned.

Hi,
your symptoms suggest transmission failure. However,the total damage could be minimal. Your being cautious could have saved total failure. Good luck and have a blessed week...........jim
