T56 noise

[j0n]

after racing last night im starting to get alot of "whirring" noise from my transmission when its in gear over like 2k rpms...and the noise increases with rpms...do i need a new trans?

[Fasterthanyou]

Sounds like it could use a rebuild. That noise isn't good, especially if it gets louder.

[Tru2Chevy]

Yea....does it do it in every gear, or just certain ones?

every gear...i guess theres no way its just a clutch eh?

You might have overheated the fluid too. Try draining the tranny and refilling with some good quality ATF. It's cheaper than a rebuild, and easy enough to do. Might get you some more miles out of it. :)

sounds like a good plan...ill need all the miles i can get out of it...whats some good quality fluid?

[NJSPEEDER]

royal purple makes a manual tranny fluid that is intended specifically for manuals that use ATF. little g uses the stuff and his tranny seems to like it

Anything that says ATF on the outside. If you need that extra 1/4 of a horsepower (if that), then go with the best, Royal Purple or Amsoil. Both are synthetic so be sure they are ATF!

how much does that crap cost? cuz i dont feel like spending too much cash on fluid if im gunna get the trans rebuilt in a month anyway

[Fastbird]

If you want some ATF that's not going to break the bank, go to a Honda dealership and get their ATF. Good stuff, a lot of guys on CZ28 were raving about it a while back.

[j0n]

cool thanks...ill go get some today

[j0n]

yea so i changed the tranny fluid but i kept driving the car like a *******...so the noise is just getting louder and now the car starts slipping every time i shift...i need money dammit :? (for a new trans)

[Ian]

manual transmissions dont slip. clutches slip.

[Pampered-Z]

Does the sound change when you push in the clutch? Â*T/O bearing maybe? Â*

Service manual listed the following for noise ( from the trans, not the clutch):

Low or improper fluid.

Worn/damaged Speed-O gear

Worn/damaged bearings.

Improper bellhousing alignment or lose bellhousing.

As others mentioned, change the fluid ( 4 quarts ) and make sure all the bolts are tight.

I've used Redline ATF in my cars for years with no problem.

Trannys suck..

[Slow-V6]

Try using a quart of Lucas or Gm syncro mesh and the rest of the quarts use atf..

[j0n]

i just changed the trans fluid...im getting sick and tired of this damn thing...im just gunna get the whole thing rebuilt with a new clutch....its gunna suck to fork over that kinda money but then at least i know its done and will be all set for as long as i own the car

[Ian]

you wouldn't have this problem if you didn't drive the car like ronnie sox! :lol:

[Tru2Chevy]
