P.S. Are the cases the same from a rear pump earlier aluminum trans to the later ones without the rear case?

The oil passages at the rear of the cases are different from rear pump models and the non rear pump models (both alum cases).
If you block off the rear passages with a plate and drill the rear pump case for a transbrake it works the same as a non rear pump case.
The plate blocks the oil bleed to the stock rear support where the governor is removed also.
Hope this answers your question.
Just my experience.
