Tranny or clutch?

Alright here is my question that i have been trying to figer out. When i come ot a stop sometimes there is a wining sound coming from the transmission. The tranny shifts very smoothy and i am unable to see a problem, Just this wining noise. I'm afraid i might be hurting the transmission. What do you guys think. My clutch still seems good. Could this be my tranny fluid level or more then likely my clutch?

If you push in the clutch and the noise disappears, it's probably your throw-out bearing.

Could be tranny. The gears tend to wine when they get old and worn. My 3rd gear use to wine big time but when it went, it was 4th and 5th I kept getting stuck in.

Drove home in 5th one day. try taking off in 5th once.

No it only wines in reverse. I come to a stop sometimes in first and the clutch and brake all the way done and i can here it. Sounds like the clutch isn't going down enough, but it shifts fine. Nice and smooth. Reverse is sometimes hard to get inot have to put it in first then reverse. This normal? First usually works all the time. How are is it to change the bearings?

Next time just put it in neutral and let the clutch out a little then back into reverse. Reverse gears don't line up all the time and needs a little spin.

Reverse trouble is normal. I I hold normally hold the clutch down push the stick into 5th then back into reverse before letting up on the clutch. It seems to help line the gears up a little better.

whirrrr sound when you clutch in depressed and stick in the first gear position I belive is normal. Every car I have had has made this noise like that. If you have to push the stick forward to make noise you are causing over travle. Do it often enough and you will cause premature ware of the first gear, but you have to do it A LOT!

Thanks guys. Just making sure all this is normal. Good to know. What do you guys recommand for tranny fluid? I thought there was a screen in there that prevents the metal chips from recirculating in the fluid? No?

no screen or filter in a stick, might have a magnetic drain plug to catch some of them. I am a magnet man and have them stuck or glued to parts of my engine to catch metal particles.

oil filter, pan
fuel line, filter
tranny and rear end

on both of my cars. I stick 4-5 on my oil filter.



The right T5 fluid is hard. some say stick to the stock ATF just change it with every oil change. Some use 80-90 but it is to thick for the bearings [fact] but people still use it. Some run a mix of both ATF and gear lub and then people like me run straight 30w oil as the JY that sold it to me said to use it. That is if I wanted the bearing to last.

Thin enough to flow like ATF but better protection while them gear slap together.

Been several long thread about it in the tranny section.

I still use ATF. I have all most 300,000 miles on it and it was only changed once at about 195,000 miles. Fluid still looks nice and red and doesn't smell burnt. I don't baby the car due to my heavy right foot, so the ATF seems to stand up just fine. Then again my Camaro seems to be one tough car to kill. With this much mileage and one small engine fire. I haven't had to do any major work. Reason for the fire was a lose alt. cable that shorted to the block. Replaced the wire and alt. and every thing was good.

I know the original ower of the car and the heads have never been removed. So I may be the expection to the rule.

They used ATF cause it needed to be thin enough to flow into the bearing and syncros right but I like a little more cushion between the gears. ATF doesn't have much of that cushion that oil has. But since it not an engine, straight weight is best.

So i guess ATF really shouldn't break down but the guys with built 350's and 400's and a normal T5 say change it at every oil change.


That is another big debate. Several thread have people on both sides.

Some say use ATF but a 305 will blow a normal T5

Then the others say, I got a built 350 and several drag season on my T5 and use ATF 60/80 mix as on the legacy suv page.

Then the guy with a 400 and a normal T5 running 80/90

And so on.

Both sides have proved their point. Both side have had *** success with either product combo. But then ere is the guys who blow every T5 with a 6 and use canola oil.


Its so tricky as you just gotta decide your self.


But the one thing we cleared up is that the T5 was not used on a 350 for emission reasons. It would not pass the CA down shift specs. And if GM can't pass 50 state, they don't make it. Why they only made a 305 stick.
