[Lock & Load]

Reading the November 2007 Motor mag in Australia Journalist... David Morley pointed out a few potentially concerning issues and theorys with the EVO X .

With the TC SST He states :

"The only glitch i can see is a tendency for the gearbox to get hot and start short-shifting in deference to its oil temperature ( two cars did it to me and it wasnt a particularly hot day )

Should this be a concern for TC SST OWNERS ?..........what do you guys think ?

About the 5MT gearbox he says .

"Mitsubishis engineers reckon weight is the reason for the move from six back to five cogs , but the more cynical among us (me,for instance)......smell a different sort of rodent .

Think about it : if you have gone to the trouble of developing a whizz-bang new clutchless box ,you have to make sure that its quicker than a conventional manual right ?
So the best way to do that is to hobble the regular manual gearbox by spacing the gears further apart ."

Has Mitsubishi deliberately HOBBLED the manual in order to make the TC SST Faster ? What do you guys think ?

"post same post in two different forum" and see who's more intellectual... no idea not until at least a year of this evo x, sure there will be bugs.

but i hope they make the sst 7 speed and 6 speed manual.

Hmmm. Thought the SSTs wont be available til next month...in Japan.
Engineers are still tweaking it.

Actually i posted in 3 different forums opcorn: , opinions are varied some have merit others dont .

Yes a proper 6 speed manual would be nice .

I read that the 5MT was supposed to be lighter and more robust a transmission than the previous 6 speed manual, but I may just be buying someone's marketing line. I'll have to look for that reference when I get home.

With respect to overheating causing strange shifting, has that been seen with the DSG in VW and Audi? Have there been any notable problems with the DSG (apart from not being able to apply both brake and gas at the same time)?

I'd be concerned. Perhaps this is why that trans is currently delayed.

I think yes and no.

Remember, most evo 8s and 9s had a 5 speed manual IIRC. However, the MR had the 6 speed manual.

I haven't confirmed it, but I've been told that the 5 speed trans is stronger and more reliable than the 6 speed in those cars.

I've also heard that the 5MT that's in the X is just a beefed up version of the previous evos 5MT. That would make me suspect that they kept the ratios the same. Again, I haven't confirmed this. I believe there was a post on this forum somewhere that had the gear ratios of both boxes.

I'd suspect they didn't intentionally design the 5 speed manual to have stupid gear ratios (that would just be silly), however, I think part of the reason that they don't offer a 6MT is so that they can sell more SST boxes (and recoup the costs of developing the new trans).

I think they will recoup their investment based on the number of deposits left at dealers for Evo X's with SST.

I wouldn't get too worried about the SST, but as with any new technology there can be hiccups. We are on the bleeding edge!

According to this post, the X 5MT ratios are:

DRIVELINE
RS/GSR 5MT
1st - 2.857
2nd - 1.950
3rd - 1.444
4th - 1.096
5th - 0.761

According to SCC, here are the ratios of the previous trannies:

EVO & EVO RS EVO MR
1st: 2.785:1 1st: 2.909:1
2nd: 1.950:1 2nd: 1.944:1
3rd: 1.444:1 3rd: 1.434:1
4th: 1.096:1 4th: 1.100:1
5th: 0.761:1 5th: 0.868:1
Final drive: 4.529:1 6th: 0.693:1

This confirms my point of the "new" 5 speed essentially being a beefed up version of it's predecessor (assuming my sources are accurate).

What's interesting is that the alleged gear ratio of the SST 6 speed is different from the ratio of the MR 6 speed manual. The SST box will apparently have these ratios:

GSR 6 Speed Twin Clutch SST
1st - 3.655
2nd - 2.368
3rd - 1.754
4th - 1.322
5th - 1.008
6th - 0.775

Mitsu stated the SST is delayed working out the final programming for Launch Control

The SST has a different final drive ratio than the manual (4.687 manual vs 4.062 SST). You'd have to calculate and print out the final overall ratios (gear x final) to evaluate the differences.

In general, 6 speeds aren't usually faster than 5 speeds, they usually are more economy oriented. Supposedly the SST offers a noticably better fuel economy than the 5 speed

I think they beefed up the 5 speed to satisfy the purists, and to give them a durable track box, not to better sell the sst. The sst is to target the bmw and audi buyers who want the performance of the evo x, but want something a little bit more refined with a higher level of technology. I consider the mr to be kind of a cheap alternative to the 08 skyline gtr. It's nowhere near as nice, but for the market it's targeting, it fits right in and yet still stands out. I don't think that mitsu would have beefed up the 5 speed only to sell it short in an attempt to boost mr sales. That's ridiculous, and it wouldn't make smart business sense, especially with mitsu being in a tight spot and wanting the evo x to sell like hot cakes. They made both models to excell in their respective categories.

but i hope they make the sst 7 speed and 6 speed manual.

With the dual clutch setup the gears have to be even. So the SST would have to have 6 or 8 gears, not 7.

A overheating problem in the TC-SST isn't going to be badly....They training video suggests when the MIL comes on to simply pull over lift the hood up till the MIL goes off (It'll say Overheat with the temp symbol above it)

Now this doesn't concern me to badly because I only drive at most some days 40 miles to work and school and home. And if I autocross it then everybody always pops the hood after every run so I wont look like I'm having car trouble.
