i recently installed a act 6 puck with extreme pressure plate... and just a couple days ago i notice this weird clocking sound coming from inside my tranny. it sounds like a metal ball is loose in my tranny. as i accelerate, the noice gets faster...and stays consistant with the speed.. but the car shifts fine, no grinding in the gears, no slippage, and the pedal has pressure. lots... my throwout bearing is new, pilot bushing is new, both the SC and MC are new. any ideas on what the sound could be? im thinking the shaft bearing is going bad (from what my friend said), but not sure. just wanted to get some opinions on what it could be...im familiar with the tranny noises, but ive never heard this noise before... any ideas?

could it be that i dont have enough tranny fluid as well?

hmm i had that same sound a few months back... blown tranny.. but i dont know if your case is that extreme.. it sounded just like how you explained it though

Transmission input shaft bearing. I'd bet on it.

^^^thats what i fugured.

yo Evan. how long can i drive on that before it gets fuxored?

Hmm... I've been driving on one for 6months already.. hah.
It's kind of a pain to replace.. some people would actually just buy a new tranny instead of replacing it.

There's a post by aznpoopy on here about the procedure.

yah i was reading that.... i could find a tranny for cheap, and not wast time replacing that. do the s14 SRblacktop trannies bolt up? is it the same or a different gear ratio?

I think you need to change the bellhousings. Not 100% sure..

Can you find me an s14 tranny for cheap!? lol.. my bearing is teh sux too..

EDIT: If you have to change the bellhousing.. it might be the same amount of work, or less to just replace the bearing.
