i was just reading all these topics about how using honda mtf or synchromesh clears up grinding gears. i have 3 quarts of acura mtf in my room and an ls tranny with a bad input shaft bearing. do u guys think if i put in the mtf that it would help clear it up in there or is the damage done already?

 

depends how bad your tranny is... i would get 3 quarts of Pennzoil Synchromesh from autozone and use it and drive it lightly going through all the gears and see if it helps... are you using an aftermarket shifter?

 

nope... its stock

 

ok cool just making sure... sometimes the aftermarket shifters will throw off the geometry of the linkage causing the synchros not to work properly and in time damage your tranny

 

i think ur misunderstanding me... i dont have any grinds, just a bad ISB, which makes the tranny make a whining noise

 

oh!!... only way to get rid of the noise is if you replace it... sorry man at least the noise goes away when you step on the clutch :p

 

haha i know right... i hardly ever downshift into 1st and 2nd anymore. the noise is so annoying. well im plannin on picking up a gsr tranny within the next couple weeks so thatll be an upgrade at least

 

that's good.. good luck on the project man!

 

The damage is done, replace the ISB and all the other bearings. Otherwise, you'll end up with bearing peices from the ISB in your other bearings and have to do it all again.
No fluid can fix a burnt ISB, the bearings are probably not even round anymore.

 

^ knows his stuff.

Here lemme show you what he means.



1997 Integra GS-R ISB. Approx 130-140k miles.

 

yeah i just changed the tranny fluid about 2,000 miles ago and there were no metal shavings. the isb prolly just started to go bad. im just gonna take the safer route and get a new transmission
