Spartan 210 Shifting with tow/haul on

[Redram99]

Hi
I have been loving towing with my spartan on the 210 normal.

The 210 tow is too hard a shift for me.

My question is, is it normal for the truck to defuel on the 2-3 and 3-4 shift while in tow haul? It is almost as if I am lifting my foot when it shifts.

I am not sure if it is good or bad for the truck. It seems to cut fuel to shift and then eases the fuel back into it when its in gear.

Thanks

I haven't heard of that happening. The shifts do have a slight "defuel" with the 210 and under tunes anyway, but its nothing major. I have never noticed it being any different with tow/haul engaged.
