Well here she goes again.
Off on another damned fool crusade.
In my quest to come up with my goal of the ultimate cool Burb I have decided as many of you have been reading to do a turbo 6.2 swap and to keep it all non computer.
The tranny was limited to a 700R4 (too light) or a 400 (no Overdrive)
Yesterday while chatting with a local tranny parts supplier about the early allisons to see if any had OD I was informed that the early (94-96) Dodge 618 tranny was basically a hydraulic shifted 727 with the OD controled by an electric signal and also the Lockup too.
Some serious digging tuned up a company that makes an adapter that will allow a chevy SB to bolt to a Dodge 618 box
The fine details of getting it in the rig are easy. Will have to use a Dodge 241 T case along with the tranny and do a little fab work on the cross members and drive shafts, BUTTTTT this will be easy to do.
Getting the OD and the Lockup to work can be done with a few simple pressure switches run off the governor pressure port and an adjustable vacuum switch to give part throttle dropout of the lockup.
This package will give good service and should be fairly simple to do.
The question keeps coming up as to why not do a 700R ?????
The 700R is simply too light and too spendy to build and then marginal on a turbo diesel.
The 618 is basically the old 727 monster with an output overdrive.
Easy to work on and cheap to build. A transgo shift kit and its pretty well bullit proof.
This may well be an interesting little idea.
We shall see.
