Passing gear question?

I recently purchased a 2018 V6 extended cab automatic 2wd which I am happy with. There is one problem that bugs me. When on the highway and want to pass it seems to take forever to drop to the lower gear when I stomp on the gas. Is there some way to shorter the lag.?

ETC or ECT(forgot what it's called) button is your friend ( if the 18s have it.)

 

^ that. Or you can shift the lever to the left. It’ll drop to 4th gear.

You should look into the Shiftsense

 

I went to the Shiftsense website . It seems to change shift points It didn't say anything about decreasing the lag in downshifting. I'll try playing with the shift lever.

Thanks

Found this online- SprintBooster V3, eliminates slow throttle response, plug and play.
SPRINTBOOSTER.COM sounds good when reading about it? It's only for throttle response works with any trans......?

 

Reconsider by bringing it back to the dealer and re-flash the tranny? I know its 2018 but possibilty that dealer didnt update it....

 

Thanks , it's due for a 5k check up soon . I'll ask them then
