Do you guys tow with the tranny in drive or use the manual shift feature? I'm curious as I was told with my older GM 3 speed w/OD to leave it in third when towing.

Thanks,
Rick

Like Sauron said, probably best to leave it in D. These new transmissions and control units are quite a bit more sophisticated and monitor a lot mot data from the vehicle, which ensures it will be in the optimum gear for the situation. The main reason for using 3 in your old GM was to prevent transmission overheating from the high load/low RPM in OD while towing.

What old GM did you have?

Thanks for the replies, I figured it was like comparing apples to oranges. The GM car(s) referenced was a 2003 Grand Prix and a 95 Buick Regal (3.8).
