    Using the clutch will be just another form of leg exercise's.... one leg might be bigger than the other...LOL

    If I'm almost stopped I usually pop into second. If I'm rolling a little quicker I usually go for 5th. for me 5th is a pretty forgiving gear, I feel comfortable cornering in it but if I find it at too slow of a speed you still have enough torque to make it work, too high of a speed you may still be able to pop it in with some throttle. glance at your speedo, figure out what speed roughly 5th is or whatever gear you like to corner in. Start to pay attention to what that speed "feels" like. That way, if you get lost when you slow down, maybe you can just slow down a bit more and find 5th. If you're too slow for fifth go ahead and brake down to second or just stop and start over.

    Once you get the feel for fifth, just realize that a bit faster is 6/7, and add that to your arsenal, etc... Basically pick a go to gear somewhere in the middle, you know if your highway speed where the big hole is, you know if you're stopped where first and second are. pick one in the middle, focus on finding the speed for that one, when you get it down add the one above it, etc...

    soon you'll be finding them all, no problem.

    Clutch=Useless once in motion. Gears will still grind if the RPM's are not right for the gear, even if you have the clutch through the floorboard.

    I'd beg to differ.

    There isnt a law etched in stone on the order of gears. one does not have to follow the number sequence.. match the gear with speed and rpm. As gentle as possible use your brake to slow down, clutch if needed to change a gear and throttle up for rpm if needed .. dont worry about floating.. the clutch is there for a purpose.. use it

    Yes but it is easier on the transmission because if you miss the sweet spot for the shift the gear box doesn't have to deal with the momentum of the whole truck. A good trick my driving school instructor taught for finding the right gear when coasting in neutral is look at your road speed, add the two digits, then select the gear based on the sum. For example 15 mph, 1+5=6 so you pick 6th gear. Or 45 mph 4+5=9th gear. This obviously isn't an exact science but a very good general method.

    That trick also helps you figure out about where the RPMS should be.. on the '5's (15, 25, 35, 45, 55) the RPMs would need to in the middle-range - in our trucks 12-1300ish. So the higher end of those gears you bring it closer to 1500 (maybe 19MPH) or lowere end, blip it up to like 9-1100 (maybe 12MPH) in 6th gear. this generally works for all gears, but it's a little tricky for me under 6th gear.

    That tranny is virtually indestructible, but not literally. They can take a lot of abuse, but not forever.

    Don't have to slow down rapidly. If that happens more than ~once a year, your attention is not far ahead enough of your truck, and your velocity is habitually too great.

    Find/learn your "idle matches": At what speed and gear match your rpm at idle. 700 rpm and 35 mph might = 7th.

    Your "splits" are probably 400 rpm. To drop 1 gear, raise rpm 400, to drop 2, raise it 800 rpm.
