James, im just gonna copy and paste what I just wrote on the other site: Spoke to Foward Motion inc. Basically , the neon transmission would work in our cars, just would have to specify what gear ratio (3.94, or 3.55). A rebuilt 3.55 transmission for example, would be $500 without core, $750 with Core. Theyre in Delaware. Also, at that point, they would reccomend doing the center diff pin mod, and installing the Quaife differential anyway; anything above 350 whp is not worth the time and money of installing a phantom grip or newskool racing lsd in their opinion. They sell race transmissions, but they are the 3 speed automatic ones with torque convertor. These can hold mega amounts of hp, which is why the neon guys usually go this route. OR you can get an SRT- 4 Transmission (if youre going the 2.4L rebuilt route). This is because of the low end midrange power the 2.4L setup brings which would be a better match for the SRT-4 tranny, as opposed to the high end power a 2.0L or 2.2L rebuilt engine would make. then you'd have to pay like $2400 and get custom made axles, prolly from Drivshaftshop.com In their opinion, the SRT-4 tranny is unbreakable.
