Have a randys transmission that I am installing in a 15 LML for a customer, First i was sent a LBZ/LMM flex plate so I called and they sent out the correct one, now when I bolt the transmission up the converter will not spin. I have installed countless of these allisons and never had this issue. I made sure the converter is seated all the way multiple times. The flexplate bolts do stick out just a hair past the face of the flex plate, do I need after market bolts for this SoCal billet flex plate? I am wondering if maybe they sent an LMM trans since the flex plate they sent was for an LMM but Im not sure of the differences between the 2 cases. Of course randys will be closed tomorrow I am sure and I really need to get this truck out. Thanks for any help!
