I use mine on county roads. As others have said it holds each gear longer on both up and down shifts. the real disadvantage i have found to it is that it will NOT let it into 4gear till about 65mph. when on a flat road crusing at 60 there is NO reason not to be in 4 th gear...which is when i turn mine off.

I looked at your signature picture in your profile. Are you really towing that trailer with the passenger car? I wasn't aware that a 4 speed in that car even has a tow haul mode. (learn something new every day.)
I was talking talking 6 speed trannys. Ours easily get into 6th at 60+ mph while in tow haul.

LOL No, that was something i did as a joke. that is my TT and my car but it goes behind my 2500 Gasser chevy.

BTW...the truck has 147K on the clock and tranny shifts like new.

T/H winds out the gears a bit. Especially if you have your foot in it. I use it.. it shifts about where I would anyway given the load I am hauling

For us Ford folks we have something called overdrive. And its normally "off" unless you purposley turn it on. So, when you run at highway speeds you are in 4th gear and the engine runs at 1500 or 1600 rpm... maybe 1750 on the freeway. If you engage O/D you will drop down a gear and the rpm will jump to 2100 or 2200.

I find that I can tow our TT on flat stretches just fine (county road or freeway makes no diff) while in normal drive mode. Any hills whatsoever and I want to engage O/D just to keep the trans from wanting to move in and out of that lower gear.
