Driving around with Tow/trailer button with not towing ?

[rosendo192000]

I was wondering if I could damage the tranny by driving with the Tow/trailer button ON when not towing nothing . The reason I ask is cause I have 26" wheels on a 4.8LS , and I just noticed that when I have it ON my shifts are alot crisper and response better since it has higher shift points .if never towed anything nor plan to , that's why I ask .
Thanks

Could you please provide me with your VIN so I can see what transmission you have? I would like to look into this for you.

Thank you,

You won't hurt the tranny......the only thing you'll probably hurt is your gas mileage.

Ouch, a 4.8 with 3.23 gears and 26" rims is probably painfully underpowered in the city.

Tow haul will reduce milage because you're pulling more RPM on average.

rosendo192000,

Operating the vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/Haul is recommended only when pulling a heavy trailer or a large or heavy load. This was taken from your owner’s manual.

Thank you

Not going to hurt a damn thing...actually in your particular situation it may actually help...not by feeling crisper, or better shifts, but helping your trans live a bit longer. 26's with 3.23 and a 4.8 is just asking for trouble...I would save some coin for a gear swap, the 4.8 is a pretty stout motor for its size so going to something like a 4.10 gear ratio will make it feel like a whole new truck with more than enough go power with those 26's.

Thanks bro , I take it really easy on the tranny (I.e take off slow till it gains speed ) I was looking into getting my gears changed but never found the right info. On what I needed or where to buy them ,much less find a reliable shop around town to have them installed . (Bayarea CA) ..
