you need higher rpms while towing like 2200-2500 rpm. The 74 turbine is slow to spool at lower rpms like below 2000. You may find it better to tow with O/D off going about 60 mph. That's what I do with 33s and 3.73 gears. Although mine is 66/74

 

ill try that

 

Sounds pretty normal just stock. If you have the boxes turned on and thats all your seeing I'd say its pretty good.
