I would've posted this in the "Fluids and Lubricants" forum but that place is like a ghost town.

Going to be doing a tranny drain & fill on my I35 before fall sets in. MaxLife users: how do you like it? How are the shift characteristics in both hot & cold weather? I'm usually a proponent of using OEM ATF but I've heard good things about MaxLife and it peaked my interest. We all know Matic-D is nothing to write home about. I'm not doing a complete fluid exchange as I did this about 20K miles ago already.

 

I've used Mobil syn. Atf. I didn't like it at all in my 02. I then switched to max life and I really like it. I've had no problems what so ever with it and it's a lot cheaper.

Ams-oil is another highly recommend atf that many have nothing but good things to say about.

I would just stick to drain and fills however but that's my personal opinion.
