I tried Redline MTL and hated it -'it was way too notchy both cold and warm. I then used RP Synchromax and it was great. Then after ~10,000 miles the tranny became really notch. So, I switched back to factory fluid and it was much better. RP seems to break down too fast, but it's great for a while. I think I'm going to try D4 ATF per Mr. 5 next time.
