It depends on what you're using it for....if you are going to road race, then Honda MTF will not hold up with the heat....in which case you'd need a synthetic like Redline in your tranny.

If you are just driving it on the street, then Honda MTF will do just fine.

There are reasons guys get grinding and breakdown with Redline...it's because it's not made for a daily driver, it's made for high temp high demands racing.

People who get grinding with Redline, are using it for the wrong reason. Same with GM synchromesh...all the hype regarding that....if you are a daily driver, get Honda.

If you are on the track, get Redline.[/quote:b03bd8fea5]

Break down cause it isn't raced? Dude, come on. Redline is a good brand wether it is streeted or raced. The Redline additives don't work well with our LSD and racing won't hep that. Some report ill effects others don't.

GM synchromesh is suspect for me at this point but I will report more later. I won't elaborate till I have more proof.

Honda MTF is in hundreds of Type-Rs that all go on track. I have owned 2 R's and both have have been on and off track with only Honda MTF. It doesn't break down and does very well.
