Clutch fluid ques

[Chattzx]

hey guys can you tell me how often you should replace clutch fluid and diff fluid?

[Z-owned]

Clutch fluid I would only do if it doesn't look clear anymore. The diff I can gurantee most people never do, for me once a year with redline 75w90 along with the transmission with mt-90

Okay cool and what would you recommend to try if my synchro seems to be kinda rough in 2nd gear?

mt-90

[Chattzx]

its especially bad if my car is cold

Second that, it will improve shift grind to at least some degree in most transmissions.

[Chattzx]

ill have to try that...is it just me with this problem or do any of ur guys Z's have a hard time shifting when cold? and do any of u guys gears grind at all??

2nd and 4th gear grind is common with our transmission's they fixed the synchro issue with the 98+ spec transmission.

okay good so its not just me bc my 2nd and 4th grind and those are the only 2 that do it. and of course they would stop fixing it on the models they didnt ship to the usa
