I have a little driving experience but have been driving an automatic and start a new job next week driving local and will be driving a ch613 mack 350 horsepower 9 speed. When i am in 9th gear and running 55 mph how should i gear down for a 90 degree turn? Some say double down 9-7-5-3-1 and some say gear down every gear and some say just coast and get the right gear before you turn. The problem with that is ill be lost and wont know what gear to get. If i do skip down, with that size motor and the 9 speed what would be a good gear to be in to make a 90 degree turn? Ill usually be loaded about 80,000 pounds. Also what would be a good gear if empty?

Empty, I'll do the same but maybe a bit faster in 5th, depending on the requirements of the particular turn. When deciding on speed for the turn, you've got to consider turn angle, traffic spacing, up / down grades before and after the turn, etc. Your gear selection will be dependent on what speed you choose for the turn.
Choose your speed first, and know what gear you need for that speed. -
Coasting is not smart!, doubling downs ok, I've done it a time or two, every gear is ok as well, If you know your going to need to make a 90 degree turn, you will need to slow early, Just my opinion
Ranger70 and Raiderfanatic Thank this. -
Would the RPM's and speed be the same in a 9 speed?

I double down to 3rd loaded and 5th empty with tanker.

You'll just have to learn to find a gear that fitts the circomstances, it won't be easy at first but you'll learn..!!
I remember when I was young (is a lomg time ago) and I was driving with my dad beside me. I hoped the traffic light would stay red untill I would have stopped completely because when it would turn green, then just like you, I had to find the right gear to continue...
Just practice a lot, shift up, shift back, try to get the feeling..!!
Good luck..!!WvDiesel Thanks this. -
4th gear sounds appropriate. but it depends on what you are dragging behind you.
common sense is the name of the game. Slower is betterRanger70 Thanks this. -

I agree with crzy. Slow down early. give yourself time to downshift, and watch your revs. all you're going to need is about 400 RPM for a little rev to grab the next gear down. You've got more of a chance of missing gears if you try and skip shift, at least at first. To start with, try going every gear. There's only going to be 4 of them since you can usually deal with getting it down to 4th to make most city turns. Just get a feel for the truck at first and don't be "that guy".
