My transmission is getting replaced because it is going up. I'm getting a used one for now because I'm short on cash but I got to wondering. If I had the cash, could I have upgraded from a 5 speed to a 6 speed for my '00 and would there be any benefit?
I don't think it would be an upgrade. You have the NV3550, a good transmission. They later switched (05?) to the 6 speed, the theory is to try and improve gas mileage. I think your 5 speed is a better transmission than the 6 speed.
