Default Automatic vs M47/M90

My 940 FT aut. has the AW71L trans, I´m looking to upgrade the turbo and exhaust+ECU´s . Will the automatic transmission suffer any pain from 200+ hp or will it be fine. What I´ve read is that the tranny is the same as in a Toyota Landcruiser ( different housing but otherwise the same )

95K on mine with around 250-275whp over the years, finally starting to show it's age. Do the accumulator mod and you'll be fine with the 71L.

you cannot compare the m47 to the m90... it's like comparing a pile of **** with something useful...

M47-Garbage
M90- Cost monies
AW71- Free and already installed.

I'd stay with the 71.

My little brother´s got a M90 in his garage, I can get it for around 200$ ( 1400dkr) doesn´t sound too bad I think.

And the M90 comes with every single thing you will need to install it into your 940 without an issue, besides human error?

Nope, got a buddy who has the flywheel, clutch, pedals and so on. All in all it will set me back around 500$

He's in Dennmark.... I gues it wouldn't be that hard to get a manual flywheel and clutch setup there, and apart from that, shifter is quite unique but from my experience, I think if I haven't already had original, it would have taken maybe an hour to adapt one from a BMW... As for driveshaft, I don't know, it seems thicker than M47 one, but I didn't measure, nor the lenght but eyeballing sets them very close. Guibo is the same between the two, as is on Getrag 260 (the big box, i.e. M5).

M46/M47 clutch master/line/slave all fit M90.


I'm just thinking out loud, not really trying to coerse OP to go with manual.

Nordmaschine: Correct I´m in Denmark, parts is easy to source here so it is not going to be a problem. Just wanted to hear if the AW71 can hold up to 250-300 hp. (on the crank).. But it´s more fun to have manual trans..
