Default How often do you change manual trans fluid?

I only have 1,300 miles on the Honda Si, but I am itching to put in some Amsoil MT fluid because I know it has to be better than the factory stuff. But then again, maybe it isn't. Anyway, how often should MT fluid be changed?

It doesn't. It relies on a computer.

Hehe..hehe... Dude, quit stressing over all this stuff! You got a great, fun little car, just enjoy it while it's brand new.... I've been noticing your posts and I think you should worry about the maintenance when the time comes, no need to sweat it now. Btw.. most manual transmissions don't require a fluid change and ones that do, it's not till 60K-90K miles.

My personal preference is around 50k +/- 20k depending on how the vehicle is driven. I would save the effort and just keep the stock stuff in there, no need to take it out right now. Just put what you want in there once you get to the change interval.

Transmissions are not exposed to combustion waste. As long as the seals are tight no contaminants can get in. Extreme loads and temperatures could "scorch" the fluid but you would almost have to abuse the tranny for that to happen. A magnetic drain plug would catch most metal particles that could be a problem. Follow the manufacturers guidelines and don't drive like you are on the drag strip and the tranny will outlast you.

The one thing I do hate about Honda is their damn Maintenance Minder. I wish they would just give the miles and suggested items to do. I do know the trans takes exactly 1.6 qts of fluid. I will just wait till the hand Minder tells me.

The words are "Manual trans fluid" not auto trans fluid.

90 wt grease is grease and not a liquid.

In all my yrs have never changed the standard trans or differential grease.

One exception was for a customer who's car was partially submerged in the ocean beach/water and I drained it for insurance requirements and there was NO water in there.

Years ago my Audi dealer told me they don't recommend changing MT lube. Don't know if that was an 'official' recommendation, but I am at 133k miles...so far so good. Shifts better than new.

Now, an automatic trans is a different story
