its fine you can leave the trans in OD on this new trans.. when towing my dad works with the trans group on it..

pulled out 24ft long trailer and model A all the way to TX in overdrive..

 

yeah all depends on the truck and how its handling the load, wind, hills.

Also if he added a hitch to his chevy it probably did not have the tow package which usually includes some tranny cooler upgrades. but i am not a chevy guy, i have no idea what they have and dont have as far as options. I stick to 1 brand in trucks and that is FORD

 

Well i guess its just a matter of opinion on the edge tuner...

But he swears by it... I wanted one for the dodge but they only make it for the 07s....

But let me know if you want to get rid of that leveling kit..

 

Truck looks great Beard, u should at least put some exaust and some minor mods on it but, I reckon that's all up to you!

 

I've got my eyes set on the Gryphon tuner for my 150. Its just like the edge but comes with custom tunes instead of the canned edge tunes.
