Finally had time to get the tranny out and on the floor today. Swing axles still attached. It actually came out easier that I thought but will be more tricky getting back in for sure. Tomorrow I hope to get the axles off and early next week send the tranny down to Geno Boyd in Elizabeth, Pa for rebuild and a few upgrades.
First pic is of the broken left rear transmission mount right where the little screw driver is inserted. Complete separation of the rubber from the steel upper plate that sits on the bellhousing. A keen eye will notice that the mount itself had to be clearance a bit back when I first installed the Soob engine with the Kennedy adapter and this may have contributed to the failure.
The second pic shows the Kennedy adapter attached to the engine and it is the bolt head on the lower right that required the clearance. This doesn't seem right to me so I'll question Kennedy next week on this.
