I took a trip to redding this weekend and on my way back i got stuck in traffic. The tranny started making an intermitant screeching noise. Now that im back, after 10 min of driving the screeching comes back but its constant now. The noise is directly related to the speed of the car though. the noise deadens the slower i go and dies completly at a stop. What do you think this is. Could this be something else. The only thing that i can think is the throwout bearing? Or the bearings on the input shaft?????

BTW i drained my tranny. the oil that was in there was like 2-3k miles old and looked brand new.

Hmm if the noise stops when the wheels are not turning but the motor still is it could be a # of things. Does the noise change at all when you push the clutch in? Throw out bearing will usually be something that either changes pitch or stops making noise with the clutch depressed or not depressed. That leaves a problem in the transmission itself or a slight possibitity that the clutch/pressure plate is having an issue.

whether the clutch is in or not has no effect on the noise. neither does the gear that im in or how much im accelerating or decelarating. Its just related to wheel speed........

Ok well if you've got the car up off the ground and can verify it is in fact coming directly from the tranny area than it has to be a bad bearing in the tranny. I'd put the car up on stands first to verify this

drain the "oil" and replace it with dex.
or atf. make sure your running the right stuff!
[Eek!] if you dont it'll overheat the tranny resulting thermal break down on the bearings and moving parts!!! [Frown]

Yeah, make sure to use Dextron III, otherwise it sounds like a bearing on the output shaft...

Its always had DEX III in it. I just thought some new oil might help.

yo Brandon, hey my phone is broken but I still check my messages. Does the noise happen in all gears? If it disappears with gear changes, it might be your input shaft bearing, if it happens all the time, it is probably your output bearing. But the gears are good right?? Maybe you should try synthetic fluid(Redline atf, i think it's D4), according to my buddy, the trans. might have dryed up and may a few fluid changes to flush it and get oil back into the bearing.
[Frown] The trans is good besides that right, sorry, I trust my buddy's judgement when he told me/you the tranny was good, it just sat around for a while.

K well everyone seems to think that its the "output bearing" in the tranny. Before I yank my tranny for the 6th time.... Has anyone ever done a bearing change on a T5 or know whats involved. If its teedious and time consuming I can live with that. Anything more (such as precision tools and measurements)the car will be taken to a shop... Thanks

Um....Take it to a shop.... [Big Grin]

I rebuilt my last T5 and it was pretty easy, but I did have to buy some extra tools...Gear pullers, snap ring pliars, micrometer are just a few that I remember....The only thing that I worried about was the bearing preload...Otherwise its kinda straight forward... [patriot]
