I have a Rambler wagon with a 383 chev. and a 350 turbo auto. w/ a shift kit. I have been trying different torque converters, starting with a stock converter; then a 2000 ;then a 3000- then back to its current converter, a 2000 stall. At first every thing was fine, until I went to a car show tonight.As far as I can remember, on my way home, the trans started to wine very loudly when it was in first gear. As soon as it shifted out of first the noise would stop. When the motor would rev, the noise would get louder. It seemed that it would also make the noise when it was in reverse, but a whole lot quieter. I am planning to reinstall the 3000 conv., but I would like to fix this first. The trans. has approx 300 miles on it. When I first changed converters I also added a aluminum pan and a new filter. This was approx. 100 miles ago. I would appreciate any diagnosis.

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.

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.

A 200-4R would work nicely but, not a stock one. It will need some beefing up. For 200-4R descent prices check with Jakeshoe, he's a member here or ExtremeAutomatics.

If/when the trans blows, it very well may take out the torque converter. GM recommends replacing the radiator if a trans blows because it's difficult to get all the metal particles out of the radiator cooler. Same with the converter -- whatever goes in the trans fluid will get run through the converter. I've seen guys rebuild a trans only to have to pull it again a few weeks later to replace a converter, and on occasion rebuild the trans again (if there was a LOT of metal particles in the old converter). Most shops won't guarantee a rebuild unless the converter is replaced too, or they flush it and decide it can be reused -- their choice.

Thanks. I went and ordered a 350 trans from Summit- a Performance Automatic co. Supposed to be good for 550 h.p. Also came with a 2500 stall converter (which is what I wanted all along). I also flushed out the cooler. Supposed to come with a good warranty. I hope I won't need it. Should be going by the 8th.
