6spd 2nd gen swap on a 1st gen?

[FoVeUrBeN]

I was wondering,

Since transmissions seems to be source of many troubles with 1st gen 3s, how easy is it to swap to a 2nd gen 6-spd?

I guess I could get a brand new one from the dealership for a relatively affordable price, but is installation a PITA?

It should basically be bolt-on since both trannies were designed for the same car.

Thx for you time,

Éric

Yes, they bolt up, but I've heard getting them in can be a nightmare sometimes. Hard to fit in.

Mitsubishi no longer makes or sells the transmissions or even parts for the transmission on AWD cars. You can get rebuilt ones off of eBay, or new ones from a company called Kormex.

I'm not sure that switching to a 6 speed tranny will solve your problem anyways. They all seem to cause problems for people.

What problems have you had?

[FoVeUrBeN]

Actually, I've had no problems.

I don't even own a 3s yet.

I'm looking to buy one though, and I'm looking for everything that could need to be changed/swapped, upgraded on the car to make it an hassle-free car.

From what I've read, the biggest problems with the cars are the brakes, the tranny and the blow-off valve (in stock form that is).

So I assume that if I buy the car, before I can start thinking about upgrading anything, I will have to take care of the brakes, the tranny and the BOV. I wanna know how much money that represents and if the car still is a good deal or not. I don't wanna buy something that ends up locked in my garage for the first 5months because everything has to be re-done on it.

I'm not sure that the brakes are that much of a problem, unless you spend time at the track, then no matter what car you have, you'll need to upgrade the brakes.

The synchro's tend to be delicate on our transmissions, but if the tranny on the car you're buying seems fine, why bother worrying about it? Mine grinds slightly going into 3rd when I'm pushing it really hard, but I've learned a how to get around it. The tranny will never be as smooth as a Civic, but our engines aren't as wimpy either. From my understanding, and I could be completely out to lunch here, but the 5 speed's can be repaired, but the 6 speeds will need to be replaced with a new one if they break. As I said, I could be completely wrong on that, but that's what the local Dodge dealer told me when I went in to get some parts.

Our BOV's are known to honk as they age, and most people just replace them to get the pleasure out of the noise that an upgraded BOV provides. Again, if the BOV on the car you're thinking of buying doesn't honk, don't worry about it.

I purchased my car figuring that I would just leave it alone and not upgrade/mod it. That lasted for about 3 weeks, and I haven't been able to stop. It hasn't been becuz of parts breaking or not working; it's just 5 hp here or 10 hp there sure feels good! :D

[FoVeUrBeN]

Thx for the details.

I'm buying the car as a project, but I want to make sure it has a good base before I start upgrading anything on it (like brakes). Modifications will be a sure part of this car's life and that's why I don't bother much with the current state of many parts, because I know in a not-so-long future, they will be replace with better ones (be it brakes, pipes, exhaust, turbines...) I won't change everything in the first 3months of owning the car, but in the long-run, not much will remain stock.

Could anyone else second this thing about 5-spd being repairable and 6-spd being only replaceable?

And what about the clutch? Is it generally good? Or does it have a known past for slipping and such?

thx,

Éric

I'll get back to you.

The brakes are not a problem.

The brakes are not a problem, but some of the guys (most of them, including me) want the best they can afford, so they upgrade the brakes.

The 5 and 6 speeds tranny are pretty much the same. We upgrade to the 6 speeds for the transfer-case, the one for the 6 speeds is steel contrarily to the aluminium T-C for the 5 speeds. (The tranny conversion is a bit more works than you think, not only the tranny need to be change)

The clutch is fine for the stock HP, but every one increase the HP and wait for the clutch to slip before changing it.

Most of the guys out there don’t think of this:

If you increase the HP you need to make sure the motor will take it, next can the clutch handle it, will the tranny brake, how about the transfer-case/drive shaft and how about the differential?

I’ve modifying and playing with car for 20 years.

my internet is being fussy right now, but go to http://www.daveblack.net/asp/3000GTLinks.asp and under 'transmissions' are repair places that deal with our Getrags.

Also never heard that brakes are a problem, and the stock Bypass Valve starts to leak only when you increase the boost, but so do nearly all cars (3S, DSM, Volvo) Stock boost is no problem for the setup. If it fails, you can pick one up for 5 bucks off of the 100's of people that have gone aftermarket.

[Snortin93]

Now if you want to do a LOT of reading, there is a really interesting thread currently on the US site about upgrading brakes that provides a lot of information, misinformation, and alternatives. This should give you a lot of food for thought.

Both 5 and 6 speeds are 100% rebuildable. Its realy not that hard either if your willing too give it a shot. I replaced some of my bearings and a few syncros last month. Shifts like new now. You can get all the parts from CRS in New Jersey, the prices aren't bad either.

Actually, you still can get a brand new tranny for the 3S. Mitsubishi never them to begin with, it's Getrag, in Germany. And they still have them, and they're still available new (or rebuilt with new parts from getrag). Everytime i've changed my tranny under warranty, i had to wait for the tranny to come in from Germany, and it was either a brand new one, or a rebuilt one with new parts.

What mitsu does, is ship the messed up tranny back to getrag, where getrag rebuilds it, and sells it as a new tranny again.

So they are available new (kinda) :D .

I rode in a crazy fast 91 Stealth TT the other day, which had a 6-speed transplant. We never even used the 6th gear... http://members.shaw.ca/dsm_power/shuffle.gif
