I have read a lot about the gear oil and tranny oil...
but I am still kind of lost...
I saw a lot of people are changing those tranny oil...
and decent people said never change the tranny oil...

I have a 2001 ZX3 5spd... with 95K on the clock!!
I want to know should I change my tranny oil or not...
if so what kind of oil should I use?
I am thinking about it because my Tranny sounds kind of noise...
and I do know if it is MTX-75 it is noise...
everytime when I try to acc. it sounds like ge.ge.gee.gee.
my roomate's dad said sounds like throwout bearing is weak...

is changing tranny oil going to help?

Use whatever the dealer had in it, motorcraft oil i think? Its fine to change ur tranny oil in ur manual. Autos can have problems sometimes but dont ask me why.

He is right.. but if u did have an auto you can change it as long as u do it every like 20k miles or so from when it's brand new. For some reason if it's been in it for 100k+ miles and u change it it looses something important from that old fluid.. idk

Well I had been running Amsoil ATF in mine, changed to at roughly 50,000 miles, 139,000 now. I was starting to get a little buzz while coasting and I decided it's been in there long enough so I picked up some Royal Purple Syncromax. Saturday night was my first trial of the new fluid and I'm happy with it so far, granted it's only 1 day. My biggest trial will be winter here. The factory Ford fluid was a real PITA to shift in -30 weather and even 0 was an issue. The Amsoil was the same warm or freezing cold. Hopefully the RP will be the same.

The odd thing is I have never had the "gear rollover noise" or any other noises or problems with my trans like everyone else has had, and I am not nice to my car in the least. Hell, I'm still on my stock clutch. So I am going to say that my choice of fluid was a good one or that I have a fluke car that was made well (being it's a Ford we know that isn't really true).
