Welp, I've been driving my car for about 3 months now with the new Vortec 4.3 Chevy motor and all is going well EXCEPT the DeLorean auto tranny. However, I believe this is related to either a problem inside the tranny or the torque convertor. I believe that if I put another auto tranny in (or torque convertor if that's the prob) everything will be fine. I've talked with alot of people and most point me in the direction of the pump being bad, but I switched out the pump and it still does the same thing which is why I'm now looking at the torque convertor as being the prob. The tranny slips during full accelleration but if you drive it normally, it works fine. I've updated my website with better info on what I've done and will be adding a few pics later as well. You can see it at www.geocities.com/at88mph_1999 It takes about 10 secs to get to the main page, but once there, click on the 'engine swap' section. I'm DEFINITELY happy with the results!!! It was well worth doing the swap, and, since I did most of the work myself, it was fairly cheap. I would be willing to bet that I don't even have $2,000 invested in the swap. If you have any questions or comments, feel free to email me. Thanks, Duke
