I was wondering do any of you guys pull with your excursion in overdrive??? This is for my wifes excursion it is an 01 4 wheel drive motor has a 40HP edge tune, 4" exhaust no cat. other than it is stock. the tires are 265's so almost stock size. I had to put a new tranny in last year at 135K miles and the tranny guy said dont pull in OD. So this weekend was the first time i ever pulled with it. I had the 12K toy hauler on it and at 60mph with the OD off it was spinning the motor at 2500 rpm and i dont like that. I put it in OD and the RPM dropped to about 1900 rpm and at 2200 rpm i was able to go 72 mph. the tranny gauge showed an increase in temperature but it was only 5 degrees more than before. So can i pull in OD? what do you guys think. Quick stats: The air temp outside was 97 degrees the tranny temp in OD was 178 degrees and when the OD was turned off it would run 170-172 degrees. the temp gauge reads from a sender in the pan.
