ITR tranny second gear has a slight whine, no other forward gears do it. it dont seem to do it when decelerating in second only when accelerating. recently switched my trans fluid to GM SM friction modified, i was told that second will whine on a ITR tranny due to the final drive , but i thought all the rest of the gears should whine equal why would second be louder?

buddy of mine has the same issue, Synchro said to get the roller bearing under the countershaft second gear.

ok thanks i will look into that a little deeper.

Sounds like an individual roller bearing issue to me, like Mista Bone mentioned.

vinuneuro

You guys mean needle bearing right?

not so civic

yes needle bearing...only bearing isolated to 2nd gear (countershaft).

vinuneuro

When they said roller bearing, I took it for the type of ones in the cases.

not so civic

technically, they are the same thing.

vinuneuro

How are they the same thing? Needle v. ball.

not so civic

i meant the roller and needle.

Honda Bull

LOL. Yeah. I meant to say needle. Regardless, they are both caged needle bearings. The diff bearings are just set at an angle vs. a cylindrical.

vinuneuro

Aren't the new B diff bearings ball-type too? I wonder if they switched the H22's to them also..

not so civic

yep, 98 i think went to ball bearings. not sure if and when the H series picked up ball bearings...maybe someone knows for sure.

Honda Bull

The LS and B16 from what I've seen are all closed ball bearings.

The GSRs and ITRs switched to the closed ball bearings somewhere around 96-98.

Never pulled an H-Series apart yet.

Mista Bone

when in second gear, the roller bearing under the countershaft second gear would not be moving, therefore cannot WHINE.

Two things.

Either due to the gear pitch the whine is normal, or first or third roller bearing is at issue.

Honda Bull

True. I still say roller bearing. lol

not so civic

ok that makes sense since that the 2nd gear engaged is spinning at same rate of countershaft speed since it's locked via the hub/sleeve. if it's not the pitch noise, that would leave not just 1st and 3rd needle bearings to question, but 4th and 5th as well...no?

Mista Bone

or it could just be gear whine per the design.

ok well im getting whine in all forward gears now , all be it very faint, i cant help but wonder if i need a thicker fluid. the GM syncromesh fm i am running shifts like a dream but the whine started shortly after switching to it.
