fully synthetic in manual tranny?

[slowguy7]

I was wondering is it possible to put fully synthetic in your motor and manual tranny for the h22? My freind has a b16a hatchback and been doing this for a while now.It even got a thread bout this on honda-tech bout using 10w-30 on our tranny fluid instead of using oem honda tranny fluid?Can this be done?

[slowguy7]

any suggestions?

Just use the OEM trans fluid. People use synchromesh and all that but I like the OEM stuff. Yes the oil used in trans are similar to 10w30 somewhat. But OEM all the way.

thanx alot dude one more thing for the oil if i have a 40,000 mile motor do I go for 5w-30 or 10w-30 oil in the motor since the motor is reasonably new?

Read the owners manual it gives you what type of oil you can run. I would think 10w30 in Socal. Thats what I run in TX.

Just go to the dealership and get the stuff there, your tranny can't ask much more than that of you.
