How often should the tranny oil be changed out for preventative maintenance? 60K? 75K? 100K? I'm almost at 100K and dont think its ever been changed, so I'm looking for a place to buy some MT-90 oil and do it as soon as possible.

 

Jegs or summit had it for a good price when I bought it.

 

I change mine every 30k because i dont really want to have to replace synchros and its cheap insurnace. tranny has 125k and shifts like butter, not 2nd gear crunch or grinding.

 

please don't quote the last post in a thread.

I schedule changes at 30k on my car also, btw.
