Now the diesel trans has a totally different converter from the gas motor ones. The early 518s did not have lock up so it is possible to build one with a good converter. They have a two wire plug instead of a three. If yours has more than three wires on the case plug it is a 47RE instead of a 47RH, later 518. The RE trans is electronically controlled with a govenor pressure solenoid so without the PCM to control it it won't shift.
