You running the torque tube, or a conversion or something right?
The tranny fill plug should fill the entire tranny, output shaft, speedo gear, etc. Now if you're using an open driveline tranny with a closed driveshaft adapter, I don't know how oil is supposed to get to the closed u-joint.
Did the ujoint break where it slides onto the torque tube shaft? Weird.
This time, did you loc-tite the bolts in, and bend the keepers over the bolt heads? Feel any vibration before she cut loose this time?
good luck
