Well, could you do the exact opposite? Put an automatic transmission from let's say a 2005 Charger onto a 360 engine? Or does it not work that way? I would guess also that some of the older engines wouldn't be able to handle the higher RPM's as well. Has anyone put a complete drivetrain setup (5.7L or 6.1L engine to auto trans minus rear end) from a newer car into a muscle car with little modifications? Not like what I have heard about taking the bottom half off a newer Magnum and mating it to a 68 Charger body. Thanks for the advice. Just trying to learn something new every day.

The "newest" transmission seems to be the 518 RH, like 94 and back. it is the 4 speed od equivalent to the 727/904 type transmission. It can be controled with pressure switches. No one currently makes a stand alone controler for mopar transmissions. Plenty seem to exist for chevy and ford applications.

The "904 based" trans has a better first gear (2.74) plus it will be stout enough for my 360 after a few minor mods like drum upgrade and shift kit. Stall speed at cruise will be a non-issue since it has lockup and OD =)

The Mopar controller were more complicated but they said it could be done. Good luck. http://www.powertraincontrolsolutions.com/transcontrol.php 36 Plymouth Coupe 318 w/360 heads 518 trans 8 3/4 rear Ga. Tech BCE'78

The 44RH or 518H overdrive can be controlled with a few pressure switches. 1 -> 3 is normal 904/727 valve body.

Good luck. http://www.powertraincontrolsolutions.com/transcontrol.php This makes me want to design a standalone controller for the RE transmissions even more 'back of the envelope' calculations show it would have to cost around $500 though... If you ever find yourself in a fair fight, your tactics suck.

Better than $750. I am sure you will get more customers that way.
