Help!! Tranny issue

[240sxlover20]

I press the clutch in sound goes away when i let off the sound comes back its like a swirling sound as rpms rise so just the sound just changed the Throwout Bearing and clutch and flywheel everything. sound is loudest in 1st and 2nd but when i get to 3rd 4th gear is quieter but still there. Gearbox Rollover? and ideas?:cry:

What oil did you use?

[240sxlover20]

i checked if gear lube was in there and it was in there but idk about what kind it is.

mine is the same. it seems like it needs a rebuilt. i changed the throwout bearing and pilot bearing too already and same noise.

Input shaft bearing. Mines doin the same shit. If u have used gl5 instead of gl4 that's why.

Try running some AMSOIL MT Oil...

If it doesnt go away after using that oil then start looking for another tranny and have a spare.
