My son has a '93 Civic with a manual transmission. I first did a drain and fill with valvoline when he first got the car three years ago. On the first test drive the shfting was not as smooth and just got worse. I ended up doing two drain and fills with Honda MTF and it was as smooth as butter. It continues to perfect today.

 

So...what information do you need?

 

Congratulations :D

 

so whats your question again?

 

Yes the new formula of honda mtf is a lot better than the stuff they used to have. I remember changing mine to the old formula of the mtf and left it with notchy shifting so I switched to pennzoil synchromesh and all the problems went away. I am now using the new mtf with no issues at all.
