Ok guys any help is appreciated.I have a 90 rs integra with an auto tranny.I have ripped up three auto trannies in like three months.(yeah 3)I am now going to a 5speed and from what I gather any Y1,S1 or J1 trannie will work. Does anyone know what mods besides axles will need to be done to get this thing right.also what cars are these trannies in I know the Y1 is in the 88-91crx.And does anyone know which is best for 1/4 mile? thanks
