On f150 when they ain’t tuned it’s better to lightly press the gas twice so it can down shift to a good gear. Then just go all gas after that, been doing that shit with my 06 ram since it don’t got manual and now that I bought a f150 I do the same. Works like a charm every time
You can keep the ford in drive mode and just lock it in the gear you want and when u hit it just upshift hella giving it more gears. Or like JR said throw it back in drive and it will shift on its own
Put that Lucas oil the thick shit it replaces a quart the black Lucas is better like 3 bucks more but use as many times needed one quart at a time mixed w regular oil from 17mpg on my 3.8 Lucerne it spiked up to 22.4 mpg highway
