Right on, thanks for the link. I'm guessing it's a getrag 221, but I've emailed them to see if they'd tell me what they actually use.
Just to "give" you guys what I've found so far is....
The getrag 221 will work in a RWD Duratec setup, though they come with a very low first gear ratio of 4:23:1.... which is f'ing low. I've read that any BMW performance shop is able to build these transmissions to handle a good amount of power and withstand moderate abuse for a bit longer than an OEM unit. In OEM form, they cannot handle any worth while torque and will need to be built.
I'll have to check again, but I *think* a hybrid clutch setup has to be used. Something like a Jag clutch disc has to be used with a LS (or maybe even a Contour) PP and FW. Like I said, I have to double check on that.
This is why I've been trying to find an alternative, like using a custom bellhousing and a T5 or any other beefy 5 or 6 speed.
There is also another option, but I didn't write down the exact model number since the Linc's went through tons of variants of slushboxes it's crazy. But, there was a V6 LS that used the same model of automatic that was used in the Mustang GT. I read this on one of the LS forums, but haven't given it much thought. A built version MIGHT be able to be put together, but that would only be good for a drag car IMO.
Food for thought. Enjoy
