i have a 2000 Si with 172k miles. for more than the last 100k miles i have been running 10w30 in my tranny with no problems whatsoever. I'm actually curious to see if anyone else here does this.


however now i have a new ITR tranny. i plan to use honda fluid, but i am curious - does the LSD require a different fluid, or does it use the same tranny fluid as a non-LSD tranny?

Thanks

 

use the oem manuel tranny fluid

 

^---------- what he said!

 

May sound like a stupid question, and it may actually be a stupid question, but is the OEM Tranny fluid that they sell at Honda better than regular old 10w30?

I know that in theory everything made by Honda for a Honda is probably going to be better, but I seem to recall a friend having a problem with the tranny fluid from Honda right after changing from 10w30 to their special OEM version.

 

lemme rephrase

1) curious - does anyone else run 10w30 in their tranny?

2) does the ITR's LSD require special fluid, or is the LSD ok with the same tranny fluid as an open-differential b-series tranny?

 

1) I'm sure people run straight motor oil in their trannies, most people however run Honda MTF.

2) No, the ITR LSD is a helical type LSD which does not require a specific gear oil. Clutch type LSD's such as the ATS do requre different weight oils.

 

I ran stock oil in my tranny. 10w30 to be exact. Now my car is up on jackstands in my garage. Why? Something in the tranny disintegrated.

Now that most likely wasn't because of the oil I used... more likely it was just the lack of oil in the tranny.

I say go with the honda-made stuff and you'll be fine.

 

A lot of people run regular oil. Honda MTF has some different additives in it thats about the only difference. My vote goes to the honda fluid

 

When I got my clutch replaced, the shop put 10w 30 in my tranny. It feels slightly notchier, and almost more accurate, imo. But, when it is cold out the 10w 30 makes the tranny shift like crap.

 

THe addatives in Honda MTF are VERY VERY different than the detergents and other addatives in regular 10W-30 oil. Having run both I can tell you with 100% assurance that the Honda MTF makes a huge difference in shift quality.

 

I know 10 second race cars that only run straight oil in they're tranmissions. However, that being said, I personally run MTF because it seems to shift a bit smoother (Likely the added conditioners). Will straight oil hurt your trans? (Highly doubtful as it makes your 99% of your MTF)

BTW, you drive your car too much. I have a 2000 Si with 68,000 on it. You have almost 3 times that. Commute alot?

That's why I change mine often

 

Every 15,000 for me. I'll stick to my MTF. Alot of people have been on the GM Syncromesh bandwagon for awhile. Im not. For me personally, Honda MTF has been proven again and again.

it wasn't a bandwagon for my friend. infamous 3rd gear grind gone after gm syncromesh. maybe he syncro wasn't as in good condition as it should have been, but the gm syncromesh let him shift w/out grinding. good stuff.

 

Whatever works right

 

Got two words for you SYNCRO MESH

Most people I talk to and do work for have no clue what Honda MTF is. People fill their trannies up with all sorts of stuff.

best tranny fluid you can get is from your local GM dealer, get some Gm synchromesh tranny fluid

yeah - i bought the Si for the sole purpose of commuting. at the time, since my commute involved 45 minutes of twisties each way, and no stop-n-go, well all i can say is 'good times'
