anyone have any idea?
tranny whine
G
hi, i tried doing a search but didnt find anything. i have a 94 tt 6speed stock. just put in new TRD single disk clutch (with new V160 fluid). new stock flywheel, and some other assorted items recommend by Curt. also put in a pair of new stock twins. i drove the car for about 4 days after this was all done and now i am getting a wierd noise from the tranny i think. at first i thought it was the rear so i changed the fluid with RP but didnt do anything. It kinda sounds like a RC car. You can hear it very slightly at idle. As the R's go up the sound gets louder. Something I noticed though. If I press the clutch in the sound goes away. I dont hear the sound if i just tap the gas when the clutch is pressed. Sound comes right back when i let go of the clutch. Which leads me to something in the tranny area. if anyone has any info would be great.
note: car shifts good. no problem going into gear. just the normal clunks and a little clutch chatter
thanks

Did you put in a new throw out bearing?
when you downshift without rev matching, or double clutching, there is a whine as the syncromesh gear spools up the input shaft/engine. it sounds just like an rc car. is this the sound you are talking about?
As FattyCBR said, it does indeed point to a worn/dry clutch release bearing.
Get the car on a hoist. Remove the inspection covers. Have some one up in the car while your under looking /listening for where the noise is coming from.

going tomorrow to put the car up on a rack and get a better listen. Curt, think a local toyota dealer would stock the TOB? incase it is the TOB so i can change it while its up. also, can any damage be done to the tranny if i drive it with a worn TOB?
i am also thinking it might be the TOB, i noticed i almost always get a clunk going into first from stop. think someone said something about that being a TOB problem also awhile back
thanks for the info everyone

i have the same whining sound from my "rebuilt" tranny... i have a new Throw out bearing with the HPF clutch/fidanza flywheel.
let me know what you guys find!! it sounds like i have a supercharger in the tranny!!
3rd gear grinds if i shift fast and at higher RPMs... other than that it's coo

yea now that i think about it. does sound alot like a supercharger. 1 and 2 are very louder 3 and 4 arent bad 5 and 6 i cant even hear it. but could just be cause i am doing like 65. Does the throw out bearing have something to do with engaging and disengaging the clutch? I also noticed some times if i let the clutch out fast there is a pretty loud clunk.
sleek: my tranny isnt rebuilt. 96k miles. shift fine even if quick. i noticed that i get a smoother shift if i go a little higher on the rpms when just driving normal also. just wierd, havent had the car since end of july get it back 3 weeks ago after having some work done. drove it for about 4 days and now hear this. looks like back in the shop it goes.

Sorry to bring this thread back from the dead but I have similar symptoms and would like your guys' input:
I finished installing my 6spd in my Supra over the weekend. There is a loud whine that comes from the transmission. I am pretty sure it is the input shaft bearings.
In neutral with the clutch out you can hear it. The sound gets louder with the revs.
The sound is loud in the lower gears up to 4th. In 5th and 6th, it is nonexistent.
In the lower gears, the sound is loud especially under load. If you get off the throttle it gets quieter or goes away when in 3rd or 4th and going fast (20+ mph).
The sound is purely audible and is not accompanied by any sort of vibration. If you had ear plugs on you would think everything is fine. The sound is loud enough to make you look and say 'wtf is wrong with that car?'
The car drives fine. Shifts are positive and precise. Clutch action is fine also.
I acknowledge that something is wrong with the trans. My question however, is whether or not it is safe for me to drive the car. Are you familiar with this? If I do need new bearings, do you know who can fix it, how much it would cost, etc?
All of the following parts are new: driveshaft, flywheel, clutch, pp, t/o and pilot bearing, all related washers and retaining clips.
