i was lookin at redline or synchromesh? i got a b16 trans that has a slight grind on 3rd gear on my b16 w/ all bolt-ons so im not pushin POWER! im replacing my clutch so that might fix the prob so i was wondering what kind fluid i should run?

 

Before Honda had their own engineered MTF they used regular non-detergant 10w-30 motor oil. 10w-30 is just fine for your B16 transmission.

Some people swear up and down that Syncromesh or Honda MTF "fixed" their transmission grinds. I have tried both and noticed no difference.

All in all, if a different lubricant helps with the grinding, it is just masking the underlying problem - worn syncros.

 

Syncromesh does make the tranny shift a little smoother, but I had to look a while until I found out Advance Auto has it. Or like mcvtec mentioned, Honda MTF and standard ND 10W-30.

 

make sure your front or rear engine mounts aren't busted. that can cause grinds also

i used synchromesh in my b16 tranny...it worked great.

 

I believe the Honda manual transmission fluid has more anti-wear additives then straight motor oil. I would stick with it. I have the same problem with a B16 trans, grinds 1-2 shift if your into the Vtec. From everything I've read the synchros are weak. Going to dive in this summer.

Need to figure out which type are best.

 

Directly from a Certified Honda Tech. Honda Manual Trans fluid is 10w-30 oil with an addative in it. However, he runs a synthetic 10w-30 in all of his race cars, with no failures that is fluid related.

 

I used 1 quart of synchromesh and the rest I put synthetic 10w-30. Mobil 1 or Castrol Syntec. Works great in my B16. Better protection than the less viscous Honda Manual Tranny Fluid.

 

So two quarts Mobil 1 or Syntec 10w-30 will be fine? Cool, can get that at the Walmart nearby

 

Today's (engine oil) 10W-30 lacks zinc. This was not so in the early 1990s. See the discussion with citations at http://honda.lioness.googlepages.com/manualtrannyfluid

Trannies need zinc in the tranny oil to be effective in "extreme pressure" conditions. Hence given a choice between 10W-30 and Honda MTF, the Honda MTF is what should be used. Note that the change frequency is less using the Honda MTF as well.

 

Honda MTF should be your only choice. honda trannys arent made for synthetic oil, the synchros need to be dry when they go together.
