bout to have my tranny replaced, i wanted to go ahead and put some "good" gear oil in it instead of stock stuff, its been notchy since ive had the car, looking for a silky shift =P

any suggestions, i have heard royal purple is the shit. but is there something better? its for a 94 mx6 if that helps, v6 5spd ( haha its currently a 4spd )

and i am not sure if it matters the clutch ( i am not big on the thechnical side ) but a stage3 CM clutch and a lightened flywheel are going in with the tranny, so let me know folks, as of now i am gonna buy royal purple unless told its actually gay gear oil? and gonna flush out the clutch fluid for something better to.

 

GM SYNCROMESH

Nothing better.

GM Syn>> Royal Purple

 

cool, new avenue to look down now i got to figure out how much i need, fuck i hate reading

 

you may want to look at keeping the stock fluid in it. new of course, but my experience has not been good with running different kinds of fluids.


synthetics or different kinds. in about 10 different cars. usually causes issues.

 

redline 75W/80W GL-4 gear oil is good stuff, gl-5 gear oils will eat some of the metal in your tranny over a period of time so whatever you decide on stay away from those.

 

Redline Heavy Shockproof is what I use.
They have lighter weights also. Never heard anything bad about any of them.

The thing about GL-5 oil in some of the older trannys is they pit/eat the softer metal syncros which sooner or later cause failure.

 

thansk for advace guys, i chose on synchro mesh, tranny will be installed this week, i will post on how i like it ^_^

 

I have never had any problems with any of the synthetics that I have tried, except they all suck in the cold until warmed up a tad... I've used Redline MTL, Mobil 1 gear oil, Amsoil, and GM/Pennzoil Synchromesh(using it right now, love it!)...

the Synchromesh is not synthetic but it and Amsoil are my favorites of the ones I have tried....
