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?

they can order it, but they should stock it.
advance auto dont stock it but they can order it alos, they did for me, autozone is 25 min away, advance auto is like 3 min away

If you have lots of grinding your syncros are already damaged.
Follow the well posted advice and run ATF+3 or +4 and not any synthetic.
Then start saving for repairs...

I used ATF+3 for a while and with that fluid it felt like it was sticky in gear. In other words it went into gear fine but pulling it out of gear it seamed to just barely stick in the current gear. So I switched back to mercon and it shifts normally again. Anyway just what I experienced, no other changes.

Demon: I've read before, and I think it was your posts, to use conventional oil instead of synthetic on a worn tranny. Could you explain this a little? Why is it better to not use synthetic?

Synthentic is to "slick" to let the damaged syncros "bite" properly.
Conventional fluid by nature is more viscous. Hence why it has more parasitic drag then a comparable weight synthetic fluid.
The ATF+3 (or +4) already has extra friction modifiers in the fluid.
"Technically" synthetic fluid could still be used if enough FM was added. There just is always that point of what is enough and what is too much...

Demon,
The ratio of mix I was told for synthetic and FM is 1/2 bottle (2 oz IIRC) of FM on top of a full fill of the trans with new synthetic.

That's not an entirely accurate amount though. It all depends on what the main synthetic fluid is.
2 oz of FM was the prefered guesstimate for the "cocktail" using the Mobil 1 ATF.
It was however just what someone felt was best for them and it was figured out on syncros of unknown condition.
It works the same as people who try MTL and love it and people that have tried it and it gave them problems. Good speculation would be the later already had syncro issues.
I try to recommend a product that is already formulated for use in manual transmissions so it has a suitable mix of modifiers in it.
I liked the MTL. Ran that for a year before axle R&R about a year ago.
I've also had very good results with the Pennzoil Syncromesh. I've had that in for about a year now. Picked it up an an AutoZone when I was buying my axles.
Though the success is not surprising, I've used GM's Syncromesh in previous cars with great success.

Wow, there is a lot of information here. Is is possible to have someone break it all down into one reply? First it was Redline, then it was ATF+3, then ATF+4, then there was some synthetic Syncromesh formula. I have 90K on my tranny, doesn't grind at all (as long as I push the clutch in all the way  ) and I was planning on doing a drain and refill on Saturday.
