I replaced the tranny bearings already, but they might be shattered again due to bent shafts, etc... Also, after all my experiments, the transmission is making much more noise, possibly due to me taking it through resonance several times. I've heard there's a transmission place in Bend, Oregon, but they charge $800 just to crack the case. Argh. I guess there's only a fine line between a hobby and insanity. Thanks for the reality check.<BR/><BR/>TimTimKhttps://www.blogger.com/profile/09059780797709299125noreply@blogger.comtag:blogger.com,1999:blog-2270124316233555550.post-67569841358115970792007-10-06T18:59:00.000-07:002007-10-06T18:59:00.000-07:00Tim: I know you don't want to hear this, but I rea...Tim: I know you don't want to hear this, but I really think you should take your tranny to a good VW/Porsche garage and have it totally rebuilt. (You can use the donated tranny as parts.)<BR/><BR/>It seems obvious to me (I'm a mechanic, not an electronics tech) that ypu have some bad bearing in your tranny. Replacing the pilot bearing (if it's anything like a normal transmission pilot bearing) will probably not fix much. It's basically non-functional except when the clutch is activated. All the rest of the time it's simply not being used. I don't think a worn pilot bearing is the source of your problem.<BR/><BR/>Probably someplace in the innerds of your tranny there is/are several bad bearings. If the main shaft bearings are bad, you will get vibrations which would otherwise be masked by the ICE engine. The proof seem obvious: The borrowed/gifted tranny did not vibrate. Viola: Old tranny BAD - New Tranny GOOD.<BR/><BR/>You've got a lot of cash tied up in your conversion ... don't cripple it by limiting your RPM's so as to prevent vibrations.<BR/><BR/>Just my humble opinion.<BR/><BR/>/rogerRoger Daisleyhttps://www.blogger.com/profile/10752698755981213856noreply@blogger.com
