flatty86 Posted March 6, 2013 Report Share Posted March 6, 2013 Waddup Guys I just intalled a used manual transmission and it seem s to shift well, But say I let off the gas in any gear, I hear like a loud vibration sounds that sounds like its either coming from the Rear or theTranny itself. I'm not sure if I put in enough gear oil... I mean I filled it and then let the oil come out until the oil was leveled with the drain plug.. I mean was that the correct thing to do? And where else can this vibration be coming from? Driveshaft has been changed and the the replaces the tranny mounts with brand new ones. I hope I didnt get a hold of a bad transission. By the way... I now have a flatty with a 88 89 lightned flywheel, 240mm clutch pressure plate, throwout bearing. all intercooled parts with the intercolled throwout bearing.... If this all makes a diffrence. How many qt.should out Manual trannys take? Thanks for your continued help on this project of mines, Link to comment Share on other sites More sharing options...
shift1313 Posted March 6, 2013 Report Share Posted March 6, 2013 if you only hear it on decel it doesnt seem like it would be a fluid issue. The pump is on the input shaft. Do you feel the vibration through the shifter? Can you explain it a bit more? there are lots of heat shields and things like that in that area that could have been damaged during install and be making noise. Does it make the same sound in every gear? RPM based? Link to comment Share on other sites More sharing options...
DieHARDmitsu. Posted March 6, 2013 Report Share Posted March 6, 2013 Check your Diff. and torque tube mounts.Jack up the car, put it on jack stands then crawl under with a pry bay. Try prying the Diff and TT near the mount areas and inspect for breaks or looseness. Link to comment Share on other sites More sharing options...
flatty86 Posted March 6, 2013 Author Report Share Posted March 6, 2013 ok....I cant really explain it... The shifter is not vibrating or anything lik that..The noise /vibration only only happens when I let off the gas in 3rd 4th and 5th gear.... (the noise is the loudest in 4th gear )The noise/vibration stops if I put the car in neutral. @Diehard I will inspec that when i get home.... Thanks guys for your help.... Did i install the gear oil correctly? Link to comment Share on other sites More sharing options...
skyle22 Posted March 6, 2013 Report Share Posted March 6, 2013 I would think that you should be fine on fluid, as that's kind of a hard one to mess up. Just fill it till it is full to the fill plug on the side of the tranny. Maybe check to see if the drive shaft rotates excessively when parked and in gear Link to comment Share on other sites More sharing options...
StarquestRescue Posted March 6, 2013 Report Share Posted March 6, 2013 Try putting the old drive shaft back in. Was the new mount one of those poly mounts by chance. Link to comment Share on other sites More sharing options...
flatty86 Posted March 6, 2013 Author Report Share Posted March 6, 2013 I put in both driveshafts.... Both do the same thing.... I bought the tranny mount on Ebay.... so i'm not sure. Link to comment Share on other sites More sharing options...
