I know this has been talked about before, but i'm curious...

Some say the auto box in 3rd Gens is good for between 200-220kW, is this at the flywheel or at the treads - can some please shed some light on this ?

And how much further if any realistically could one expect to be able to push it after the fitmint of a tranny cooler ?

i don't think any version of the magna's auto box is good for more power other than stock. they are a pretty poorly designed piece of hardware. i am really interested to know if a tranny cooler will prolong the life of the autobox or even some say let it take more loads.

I would say at the flywheel for sure.They r pretty strong mines holding out the punishment well.But has slipped bad once.

well i have had more than 140kw at the treads for more than 6 months now and my auto box has had no problem at all, 150kw at the treads is all i am going to put through it though and i have had no reason to believe that the auto box cant handle this easily

it doens't mean that if you have 140kw atw means the auto tranny will go dead on you instantaneously or even in the very short term. you are progessively getting there, shortening the life of your auto cogbox with excessive power inputs. and in engineering design, there is 'redundant' design so that means a machine or a device is usually over-designed for a little over the specified max load it can take. and i am saying the magna auto box isn't particularly a good piece of design cos i honestly believe it simply cannot cope well enough even with the standard max loads that the engine is outputting to it. if you're driving the car easy that's fine but if you're flooring it out of every corner frequently you'd be having some problems sooner rather than later. having said this, the magna is in essence a family sedan so mitsu engineers didn't really spare a thought for lead-foots like us did they?

Well i have had 130kw at the wheels or more for about 18 months now, i drive the car fairly hard. The thing is there has been no issue what so ever, gear changes are fine. I would asume that after this period of time if it was going to have problems it would be starting to show, especially consiering that my car is appoaching 140000km mark. In my opinion the auto box should be able to handle moderate power upgrades without an issue as long as your car is maintained in good condition. Through a turbo in there then it would be a different story but staying N/A should be fine

the 220Kw max is at the fly for sure, any mechanic will tellu the trans is the weak link in the magna. even a trans specialist said to me they a cheapo unit. saying that aside, the cars are rated to tow 1500kg so arent really piss weak, just not a good base for serious power-up

Does anyone know what part of the gearbox goes? All well and good to say they're weak but it what sense? torque convertor?, hydraulics? bands? Maybe it's something we can modify?

Does anyone know if another auto trans out of a different mitsubishi model will bolt into the magna that is stronger?

the trans that went on my stock TR at 200'000km it was the computer problem.
what i was told by a trans specialist is they r really a 4cyl unit used on the v6 but can be toughened up tho with solid spline and fewo ther goodies, just not beyond taking about 360Nm at the fly still long term reliable, and that should be good enough for all N/A mods or moderate boosted :cool:

Is there anything you can do to make these stronger? ie better clutch material or upgraded bits? ive been through one box already and the second one flares when warm.. the second one was a peice of crap from the beginning though (mitsu recon)
Argh!

if u know what went in your auto, we will know one part that needs to be strengthened???

well i dont really know much / anything on the scheme of things about autos..
but on mine, it was slipping, its like the clutches or bands that they use have got crap clutch material and cant grab onto the planetary gearset well enough..
mine was slipping a lot, and i think i managed to burn the clutch material after some heavy driving / drifting action (not on public roads)
thats what i reckon anyway..
