What speed to downshift 10 speed transmission?

play it by ear is all I do. each truck is somewhat different.

to do it at a faster speed,you need to rev it waaay up.

 

I’m with @Numb every truck is different. You could have the truck that rolled off the assembly line right behind yours and it’d probably shift a bit different. I just want to say I do find your formula interesting. My buddy’s brother is in truck driving school and he said their instructor told them if they ever get flustered in the high side, a good rule of thumb is to add the digits of your speed together, and the sum is what gear you should be in. And what you said goes along with that.

 

Tell your instructor to pound sand. Do what works for you

 

Each Transmission is different. The part about yelling when teaching shows me that's not a teacher. If you understood you wouldn't need a teacher. It also varies when the truck has a load under it. Watch your speed and rpms. If you had a good teacher who would explain how it is done & patient you wouldn't have so much anxiety. Don't be so hard on yourself try to remember it is done. I hope all the best for you. There are plenty people here who will help you. Stay encouraged you will get it. All the best to you .

 

To be honest with you I don't even do all that down shifting coming to stop signs or certain situations. That's just me. Yes you need to rev it up to float the gears but you have to hit the right gear according to speed.

 

There is no speed.

Your main shift points is two RPM numbers of engine speed....

For example at 1250 you downshift before you start to fight the truck with it bouncing too much and stalling. At 1600 you upshift unless you are already at governor or top speed.

 

I hit the brake, mash the gas and pull it into gear.If you think about too much your bound to miss.
