Alright guys here's the problem, I can be taking off in 1'st and most of the time I can hear the driveshaft shaking violently, and it's really bad in reverse.m but after I get going its smooth. I had a mechanic install a new clutch and he said a tranny mount was broke so he replaced it. Another thing, if I'm cruising at say.... 20? I can romp on it pedal to the floor and I can feel something in my feet like it something lifts up beneath my feet and grinds against the chassis underneath my feet, but without a grinding noise you know. Idk what it would be, loos driveshaft maybe. Tranny mount loose? And with driveshaft shake,mi had my friend put it in gear and without pressing the gas I had him let out clutch slowly as I was in the pit and i could see and hear the shaft shaking but idk. What do you guys think?

ur u joints are fine? motor mounts and are the bellhousing bolts tight?
I would imagine if the bellhousing wasnt tight then the clutch would feel terrible and make some awefull noises

I'll check the bell housing once I get a chance, thanks for the response :bigthumbsup

Sounds like 2 separate issues. First of all, when the new clutch was done was the flywheel replaced or resufaced? Most of what you describe sounds like clutch chatter, a few causes could be flywheel surface, grease, oil, fingerprints on the flywheel, etc.

The second thing you describe, I'm not real certain here, I'm not sure what you are describing, but that sounds like...

The clucking sounds like a problem with the U joint(s) or the transmission mount, but hard to tell from what I read... my gut tells me there is a problem with the install work, especially the flywheel.

I still think, as we discussed in your other thread related to this, that it's due to running an 11" clutch disc with the 10.5" flywheel (OP replaced a bad T45 with a 3650; just fyi for those who weren't in the room last time). I think the clutch disc isn't making proper contact to the friction area on the flywheel and is riding on the edge of the ring gear and thus is not engaging properly.

Yeah that information does change things quite a bit, it could be hanging up on the gear where it is raised... you're gonna have to have a look from underneath at the clutch, etc... no offense intended, but sounds like "wall of shame" entry, trying to save a little by cutting corners and end up spending more to put it right. Good luck, let us know what you find underneath.

well when i bought the clutch the door jam said i had a t3650 transmission so i figured well ok lets get a t3650 clutch. and i had em put it in and it felt weird at first but i thought it was needin a little breakin in to do so i waited, 1500 miles later its still doin it. so i figured ok... so the ******* replaced the transmission without tellin me :nono: bought a new throw shifter for a t45 and it went in perfect without stickin up so im thinkin, last time i ever buy an 01. gahhh:nono:
