it seems to me that the rear planetaries are on their way out. if youve got noise in 1st and reverse only and its gone in 2nd and 3rd.
If it was behind a stock engine it may last awhile but, 493HP isn't stock. The rear planetary/reaction carrier is in the rear of the trans, so it's an R&R. May as well rebuild since it has to be completely disassembled.stanjr41 said:That sounds expensive. Is that something I can fix or is it an r&r ? If it needs a total rebuild, is there an overdrive that you can recommend that doesn't involve refinancing my house?(200r4) also, is it possible to drive it(baby it) until it blows or would it take out something else when it blows (converter)? My motor dynoed at 493 hp.
