[QUOTE="RSK, post: 1475053, member: 13279"] Exactly, tow haul locks it out, and it won't shift into OD until 70mph. So if i'm towing heavy 10k plus i just roll down the highway at 60 or 80 there isn't an inbetween with 3.55's unless i lock out od then i can do 65-70 but the rpms are similar to a 450 with 4.88's and you're running 2500 rpm down the highway [/QUOTE]
