At 350rwhp my stock tranny was slipping at the shifts, so I would stay at or below 300rwhp if you want the tranny to last very long.
Thanks for the info. another quick question is ther anyway to make it shifter harder? do i need a shiftkit , stall converter switch, elecrtonic tranny controller?? lol what do i really need to do. The stock tranny shifts way to slow Thanks Brett
You'd need to upgrade the valve body, thats what controls how it shifts.
who makes a upgraded valve bodyfor the n/a trannys? ? and can i put it in wihtouit having to do a complete re-build thanks Brett
Sound Performance does, but I don't think they recommend the valve body mods without building the rest of the tranny. I think L10 sells the valve body mods seperately, but I've heard questionable things about them.
