I'm having problems shifting (a lot of grinding in 1st and 3rd gears) and I was thinking of changing my MTX fluid. I've read posts where you said Redline MTL is very good. However, you mentioned that you are now using Pennzoil Syncromesh. Which one would you recommend? Should I try one first then the other?
