First off, it's an 02 I35 but part numbers should be identical.
Started hearing some weird noises/rattles under moderate load in 1st and 2nd. I'm draining a quart of fluid tonight to look for metal.
Do these transmissions require any kind of reprogramming? Or just a battery reset/disconnect overnight and let it idle for 15 minutes? I found one near me for $350 with 90k miles and 90 day warranty.
Also, do you have to fully drop the subframe or just loosen it? I'm reading some conflicting posts.
Thanks

 

from what I rememebr 95-03 have the same transmission

 

Just install it and go. You don't need to remove the crossmember.

02-03 have an extra sensor. I put a 00 trans into an 02 and it worked but had a code.

 

Thanks, all. Glad to know a reprogram is not necessary.
A youtube video I had pulled up had it's title labeled wrong. It was actually a 2007 or something that had a much larger crossmember. He was only under the front of the car and I never saw the body except a quick pan past the front bumper where I could recognize the year.

I was at work and doubting my memory of my old 2000 versus my wife's 2002. I got under it yesterday. The center crossmember makes it a pain to get to the torque convertor bolts, but I think I can work around it to where I don't have to suspend the motor from a cherry picker and remove the center beam.
Drained some fluid. Maybe 8-12oz. Like 4-5 tiny flecks in bottom of the pan just from that little bit of fluid. I do see a couple fibers suspended in there but unknown if that was from the paper towel I wiped the pan out with. It was after dark using an LED so I'll go look at it in the sun today.
