Im not sure if this has been posted before, tried searching but it didn't get me anything relevant. Has anyone thought about swapping the 2k2 tranny into a 4th gen? More specifically the automatic tranny. After driving a 2k2, it feels a lot more driveable. That could be the extra torque, but it seems a lot more intelligent, ie it downshifts at the slightest touch of the gas. I would think it may be able to handle the power of a supercharger or turbo running at low psi, quite a bit better than the stock 4th gen auto as well. I know most of the responses will be "just swap in a 5spd" but my question is, is it possible to do?

 

Isn't the 2k3 a 4-spd auto? I don't think it was the tranny that you experienced. You may have been doing the drive by wire thing in your perception of responsiveness. The newer cars have 5-spd autos and the newest are 6-spd autos, so I wouldn't going to great expense to do anything with a 4-spd, they've been around since the early 80's.

 

6 speed auto? You didn't mean in a Maxima right? At least I hope not

It would be nice if I could get a 5 speed auto from the 2004 to function correctly in my car..

 

its most likely possible, but just isnt worth it to do. the cost alone of a used 2k2 auto tranny, vs just building one up wouldnt be worth it.

 

5spd is so much better, and since you are willing to shell out money and do a swap, why not just get a 5spd swap?

 

some people want auto

 

ecu controls tranny if im not mistaken. you would have to get you ecu to be compatiable with the 2k3 tranny.$$$$$$$$$$$

 

Why not get a 6 speed auto, from a 745il and do it right.
