I replaced the MTF in my 1992 Accord with Amsoil Synthetic MTF. The shift quality before was quite bad, especially when cold. Now it is much better. Second gear engagement still requires a bit of a yank on the stick, but on the whole much better. Cold is now not an issue.
The car had 144K miles on it when I replaced the fluid. I don't know if it had every been replaced before, but the oil didn't seem to have any metal bits suspended in it. Changing it was a piece of cake.. except for refilling it through the top hole using the big syringe/plunger. Basically you need to keep sucking out of the bottle then emptying it out into the hole, until oil reaches the top. I would let is settle for a bit before you are sure you have it completely full.
