Manual Transmission Fluid Change

Jwaite90 · 08-03-2014, 08:37 PM

This may be a stupid question but it's important to me. I'm somewhat new to owning a Z. 6 speed manual. I bought some royal purple transmission fluid and I dont like it whatsoever, oem is wayyyy better. Is it possible I purchase redline MT-85 and have my fluid drained and restored with redline? Even though I just had the royal purple put in a few weeks ago? Will this mess up my transmission at all? Thanks

you put in RP tranny fluid and want to change to RL tranny fluid? why would you think changing often would mess up the tranny? you think RP hurt it some how?

if you think it hurt it, drain the fluid and check for metal shavings in the fluid. if it looks ok then just refill with RL as the stuff in awesome! do the rear diff too with RL 75W90 GL-5.

whatever fluid you get make sure it is gl4 if you want it shift great. the gl5's are to slippery for our synchro's

Both Redline and Motul are excellent for the Z trans and diff. Currently using Redline.........

Maybe I worded my question wrong. I'm aware that redline is GREAT.. What I need to know is can I put redline in my car even though I just added royal purple a couple weeks ago?

Yes.

Edit: the only problem would be undue strain on your wallet
