I've searched, lots of noise out there on this topic.

I have a trackday on Sunday. Just got the car in yesterday. I don't think the tranny fluid has been changed in a looong time.

from searching the consensus seems to be either Honda MTF or GM syncromesh. so I think syncromesh comes in several varieties, with and without slip modifiers.

It's a Y21 5speed with a stock ITR LSD.

any recommendations? cars going in the shop tomorrow for brake/clutch bleed, tech inspection, lubricants change, etc.

thanks!!

 

You don't need a slip modifier with the OEM/helical LSD, that stuff is for clutch type LSDs.

I use Honda MTF.

Engine oil works fine too. I use Valvoline Durablend 10W-30 (same weight as in the engine). I was told not to use the full synthetic in the tranny when using brass syncros.

 

I use Honda MTF in the Type-R tranny, at one time it had "normal" oil in it, and it made weird noises during slow speed turns.

 

i never had good luck with the MTF from honda. It would be fine for 3 or 4 laps then it would start to grind on all the shifts.

I started running redline MTF and it was fine for the whole session.
