Hi all,
I was thinking of replacing the transmission fluid with a mixture of Redline MTL and MTL 90 (50/50). Is this a good idea? The transmission is shifting ok, but when cold I feel I could use some of the smoothness that Redline products seem to offer. But then there are those stories of Redline MTL destroying the Getrag-6 after using it for a longer period. Is there any truth to those stories?
Then the differential. Of course the Castrol SAF-XJ 75w140 is the recommended fluid, but some have replaced it with the Redline 75W90 product. I was thinking of going this way too, but have doubts. Should I just stick with the factory recommendations (even with the tranny?) ?
What do you think?
rgds,
Tero
