Exploding Torqueflites

#1 thing...if you ever break a driveline part....u joint..driveshaft...rear gear..axles while a 727 TF is in low gear...you must...must take the trans apart and check the rear sprag rollers and springs....OR it will go boom ......

a 904 will not go boom...but the sprag still needs to be checked ....the roller and springs can be bought less then 5 dollars on the internet...
