dragula, how did you handle to wiring of your OD? i am getting ready to put a 500 in my 77. i am thinking two pressure switches on the OD and lockup engagements with a vacuum cut-off switch to kill OD for passing. any part numbers or applications of the stuff you used? thanks, jp in the land of oz.



There are a couple of things needed to make these really live in ANY aplication. The OD sections work off reduced shift pressure, this is bad. Also, there is a larger clutch pack available, and the VB needs to be modded a little.

All in all, it works awesome. It barks 2nd gear every time and I have shifted to OD at full throttle at 6000rpm numerous times with no slippage or any issues.

Make sure you get the right parts from SMR, otherwise you will be pulling it when it quits. There's a lot of little details to get correct and its not worth doing it twice.

As for the OD, mine is done off of a floor mount dimmer switch. No vacuum switches or anything like that. When I street drive it, I usually just leave it on all the time. When it shifts into 3rd, it will then again short shift to OD after gaining another 500rpm or so. It basically drives like a regular car when I leave the switch on. For passing gear, you do need to kick it out of OD though.

I run only ATF +4 in it, same as my last diesel and that trans lasted 10 years.
