James, Just how custom is your new CG? The OEM housing has a microswitch in it that electronically detects the position of the shifter. I have heard that the signal running through this switch is a low voltage and is subject to dirty contacts and possibly picking up noise. Another possibility is that you might need to adjust the shifter linkage controlling the switch. As the linkage gets hot, then the dimensions change and get out of tolerance. That cross-over exhaust pipe over the tranny really heats things up. I've done some reading on the matter and learned that the old DeLorean design is unsafe because there is nothing to stop the transmission from downshifting while cornering as obviously this can cause the rear wheels to loose their grip. Newer designs (such as in the Porsche Tiptronic) detect lateral acceleration to stop downshifting while cornering. When Bob Brandys put a Porsche 4-speed auto tranny in one of his D's, he used an aftermarket computer that uses this technology. The stock Porsche configuration uses a positive ground which makes wiring into the DeLorean a little complicated. There are a lot of technical issues involved such as you need a way to reduce horsepower (like retard the spark) so that shifting isn't so hard. If you came up with a custom computer that addresses these issues, I'm all ears. :-) Walt ------------------------ Yahoo!
