Tranny noise

Hey guys. I just got my first car. Its an 83 5.0. I put a different 302 in it and a tremec 5 speed from a 88 gt in the car. The car i got the trans from had been rolled 3 times. Anyways, as soon as i put the car into 3rd gear, i heard a whine/howl that sounds like its coming from the trans. Does anyone have any ideas what it could be and how to fix it on a low high school budget!

First check the fluid level, if you've already changed it did you use synchromesh fluid?

Its full on fluid and no i dont think so..? I just ordered the tranny fluid that the local parts store suggested to me and put it in

And its a bit of a pain to get it into reverse. Is the reverse thing normal with tremec's?

Pretty sure they call for synchromesh, it's made by GM. My Tremec 3550 called for that. They are much more mechanical feeling V. a T5.

Sounds like it could be a bearing and with the reverse problem try putting it into second and then reverse and it sometimes it will go in easier

Not synchromesh, the t5 calls for dex/merc AT fluid. I got a warning label with mine that use of synchromesh would cause damage and void the warranty.

Ya but thats a newer transmission. Possibly tremec made some upgrades to prevent the whine with a short throw shifter?

That's true and my Trans doesn't have many miles on it and I put hardened gears and stronger synchros in it! I would agree with previous suggestions change the Trans fluid and see if that helps

Ive also heard from my dad that it could possibly be my syncros? Is that a possibility?

If it whines in gear then it is not your synchros. Synchronizers are only used when shifting from gear to gear. If it shifts up and down through the gears smoothly your synchros are fine. If you have difficulty shifting from gear to gear or have grinding issues then you may have a bad synchro or bent shift fork.

About shifting problems it could also be that your clutch may not be disengaging all the way

None of what I spoke of above will cause a whine while in gear though. A whine has to do with a bearing, a gear meshing problem or under filled transmission. Remember a light whine can be a normal condition but it shouldn't get louder with higher rpm, and wrong fluid shouldn't cause a whine. It will just affect the friction properties of the synchronizers. Certain fluids have diff additives that affect friction of metal on metal. Some metals are made to grab one another while submerged in fluid (brass synchros also known as blocking rings) and others just need to stay lubricated (gears and bearings).

I have that same problem tbone... Lmfao

In my 01, I get a whine that gets louder as the rpms go up. Starts whining at about 1700-18 rpm in first gear. That's the only gear and also I don't have the t5. So I dnt think I'm any help at all lol

That's interesting, it's probably normal. I have the same light whine in first and second when slowly accelerating but not
under hard acceleration. Then again I am running a tremec 3550 so it's apples to oranges. My thoughts are that the main shaft is spinning so slow in first and second that it is easier to hear the gears meshing under the high torque load of the lower gears. Just a guess really but there is logic to it
