A body with an A833 and a Gear Vendor installed

The two A833OD transmissions I've installed have been working great for street driven cars. Both are behind pretty good running 340s and I have yet to see a down side. Of course I don't do a lot of powershifting at high rpm. I do however let them eat in the first three gears but not shifting with my right foot planted on the floor. I see a lot of people on this site who have had problems or just don't think they will hold up. Both of the transmissions came out of pickup trucks so maybe that's the difference. That's why they are long tailshaft but of course the same length as a 727 auto. If you plan to drag race the car with slicks or drag radials, that may have a detrimental effect on them but with 245 radials, no problems have I had. OD with no tunnel mods necessary. Just my 2 cents.

I also have 2 factory 833 OD's which I would tear apart and rebuild before installing. While I am at it I would change out the mainshaft and tailhousings to make them A body tranny's. I already bought an aluminum tailshaft housing and the weight difference between it and the cast iron one is phenomenal. I just checked on the TKX install and yowzah, hacking the torsion support is exactly what I wanted to stay away from. So here is what I am going to do. I will run the factory OD all aluminum with maybe putting in the countershaft steel bushing mod. If I am not happy with that I will check with people who have the Passon trans mod in person including talking to Jamie at one of the big shows or maybe even going to his shop, including hitching a ride in a vehicle so equipped. If I am not still satisfied with that option I will do the B body tans with a GearVendors and hopefully end up with something I can live with. I really appreciate your feedback on the factory OD unit since right now that would be the easiest avenue to go down. This car won't be a race car, I am mostly building it as a reliable cruiser that will hopefully knock down close to 20 MPG (71 Dart 5.9 Magnum with factory MPFI, probably 3.55's with possibly 29 maybe 30 inch tall tires and some form of OD yet to be decided). I might even throw a stock 4 speed in it if I know it will end up not leaving town for a long road trip for a while ( all aluminum also of course ).
