My transmission needs a rebuild, I plan on doing it myself this coming spring. I have nothing invested in the 2004r yet, mine is bone stock.
My car is stock engine, TA49 turbo, 60lb injectors running E85 (will be switching back to gas now that I moved to Houston), stock intercooler, stock maf etc. I do not plan on anymore engine mods, I want to max out the current combo and stop there. I am more interested in drag racing with a stick.
I want to go with something that I build once and will be happy for years with just fluid changes. In the past I know guys were trying the AOD. I don't know what happened with that experiment. I have friends that drag race with the 4R70W(newer version of AOD), it handles lots of power without breaking a sweat, and they are cheap to build.
I am just looking for some opinions on anything better just trying to think outside of the box a little bit. I have been out of the buick game for ~5 years while my car has been sitting. I am here looking for opinions from the guys that actually know these cars. I am sure if i post on tb.com I would get a bunch of suggestions to install a 4L80, which I am not making enough power to need.
