Magnum 318 info

Hope you get a solution DionR
to clear a couple of thing up
OD units are the same outside
It's the 904 vs 727 and Bellhousing that is different 904 is also shorter in the TF part which does make an easier install
My experience is mostly RH and 47 guts into 46 etc, early/ late RH, straight cut diesel gears in the early 46, etc
For those running these transmissions including the 5 speeds Transgo has new separator plates available
Anytime Back to second -which I needed and which cannot be done with a shift kit- new valvebody or separator plate is required
and for those with Electronic transmissions- post 1995 you can adjust the line pressure without setting a code or going into limp mode
lots of other features check it out
DionR- the E transmissions sense line pressure- go out of range and they do not like it- hence the new separator plate- brilliant solution

What fishy68 said but Get a A-999 and one with a LU converter The double wrap low reverse band cannot be added to an A904 and you get more clutches
What the 727 gives is durability
on the early small spline trans change the pump and input shaft- then use a later converter- go lu while you are at it if on the street
you can even use the late "flats" converter and pump instead of the "slot" converter- it has more flow
