Hello,
I do have a 1989 Cummins with 727 trans and need to have an OD Transmission.
I know there are some Diesel 518 out there but rare to get one.
I might get A-518 Gasser 46RH Transmission and was wondering if you can morph those two.
Using the front/main case from the 727 with the cummins bellhousing and the tail and all internals from the Gasser 518?
Obvioulsy would need a Diesel Converter due to the different splines and as well the governor from the Diesel.
An overdrive unit will not bolt on to a 727 case.
Diesel got either the early 727 or later the 47 or 48 RH/RE, never the 46.
