On the transbrake solenoid issue, just disconnecting the electrical switch might not make any difference. Is the solenoid external, mounting where the original modulator was? If so, you need to make sure that the valve that the solenoid activates is installed properly, not backwards, and moves freely. Is there supposed to be a spring on that valve? Is it there and installed correctly? Is the solenoid installed to the proper depth?

I will check the clearance on the convertor and flexplate; the convertor was spinning freely after everything was installed, no dragging. The brake does have an external solenoid however this was never removed and it was all working fine prior to me removing the engine. The original B&M switch was wired through a Dedenbar RTD-6 Delay Box, I have since removed the delay box and ran a wore of the main solenoid for my starter to one side of the switch and the wire from the solenoid on the brake to the opposite side of the new transbrake switch.
