    I've never driven a truck with a 10-speed tranny. I've only driven 18-speeds, and on a few rare instances, a 13-speed. Since I will soon have to go out on a road test with a 10-speed, I'm curious to know what the shift points are. Thanks.

    1-3 you can figure out, 1 is granny. 4th for really low speed turns, like uphill into a parking lot. 5th gets you around most corners, 6th for a wide smooth one. 7th, 20-30, 8th, 30-42, 9th, 40-65, 10th, 50-106. Downshifting (jake) you can hit 8th at 50, 9th at 65, 7th around 40, etc.

    Course none of that will apply if your truck is numbered differently and has a different rear end. It won't be much different than driving the 18 without splitting any gears.

    If you've driven 18's, I'm sure you've shifted at times without splitting. In fact, if you still have access to an 18, drive it without splitting any gears (empty). 1 st gear on a 10 is granny, so you're just using 9.

    In a straight 10 (not those POS super 10's) I normally start out 2nd or 3rd (depending my mood) when I'm empty on level ground. Most load's on level ground I start out in 2nd. I think I've only used 1st once or twice and that was because they were beer load's and I was stopped on a steep backward facing hill at a red light. If I'm bobtailing I'll start in 3rd or 4th and skip gear's which takes a little higher RPM and slower shifting. I couldn't tell you the shifting RPM range's because I only used it at Prime because of the fuel milage BS they complained about but other truck's I just go by the sound of what the engine is telling me. I guess it's more of a "natural" feel and touch if you know what I mean.

    Try this site and also check youtube as there are several vid's on there.

    Hope this help's. Good luck.

    like he said.you can start in 2nd more often than any.just go through your lows then when out of gear swith your selector to high and go back to 2nd and so on.

    start out in the highest gear possible shift as soon as possible and everyone will believe you know what you are doing.

    When all else fails 1500 rpm and 15 mph equals 5th gear.

    Actually you want to go back to 1st (6th.) The gap is to wide between 5th and 7th to get away with it loaded. Unless you're running downhill.
