Heat will certainly cause problems considering steel doesn't get any stronger as it gets hotter.

All metals, made for normal ranges of temperature (i.e. street car), will experience loss of strength at elevated temperatures. Solid state physics.

If I could build a perfect box (for me), I'd want my VIII 5 speed box freshened by TRE and have an IX 5 speed's 5th gear in it.

This is what I like to build.

EVO-8/9 RACE prepped transmission.

Stronger, longer 1st gear with a longer 4th gear and a shorter 5th gear. This is the best for road racing or drag.

They can both hold the same HP don't let people bullsh t you! You will get all the 5 speed people tell you theirs is better because they dont have a 6 speed. If you beat on either they will f ck up. In any way if you beat the car you should call shep anyways reguardless 5 or 6 speed. And dont let anyone tell you shep doesnt work with 6 speeds CAUSE THEY DO!!!!!

actually, the SE has diamond black BBS'. same as the MR with a different color coat.

actually, the 6-speed does heat up a little more. it has more gears in equal space with less fluid to dissipate heat. even though it's case has heat extracting fins on it, i'm sure it would benefit from an aftermarket cooler.

You have no idea what you're talking about.

You have not earned the right to question Jon Ripple or his information.

I have 2 6sp, and 2 5sp transmissions. Guess which 2 are broken and which 2 are in use?

Jon has been dissecting, testing, rebulding and strengthening Mitsu transmissions for a many years. When your credentials meet or exceed his, feel free to share your professional opinion on gear strength.

Thank you SOOOOOOOO much John. PM me with details OK? I know I don't have the experiance that you do, but I am facinated with engines, transmissions, cars in general, so I love learning new things like this from knowlegable people like you.

Thanks again,

Gears.. Would a trans oil cooler and pump help gear/trans longevity for street use at all?

If you're reaching excessive temperatures with aggressive street driving, then a cooler setup would certainly be beneficial. If you're not, then it addresses a problem that does not exist.

With the new offerings it just doesn't make sense to get the MR for track duty.

Instead of dicking with a tranny cooler you're probably better off just reading the temp and not overheating the darn thing.
