upshifting RPMs

Patience is the first thing, try dropping 50 rpm at a time till you find the spot, try shifting slower, faster. You will do fine. Every truck and trans are different. My Pete likes 1550 to 1650, The International likes 1350, dont worry, you will get it.

 

Depends on the situation. Uphill and heavy rev it to the limiter before a shift and shift quick. Flat road try around 1350 - 1400 and let it drop about 300-350. Most important just relax and try and get the feel of it. I'm sure you know to not use the engine brake while up shifting.

 

The brand of truck does not matter what rpms you shift at. Sorry

 

My '10 liked 1300 dead even.

 

Thats the reason why no one should ever have a 10 speed specially if your driving in hilly country 13, 15 , 18 speeds are the way to go that way you've got your splitter gear to choose without having to really strain the engine, having said that if you are in a 10 speed i always find if your heading up a hill and the revs start cutting back you get a feel for your trucks engine i'll change down around 1200rpm again alot depends on the horsepower and grade of hill/mountain.

 

To make a clean shift it doesn't matter what rpm you shift at. It's all about the rpm drop. But if your truck requires a bigger drop or if you're heavy or going uphill if you shift to early you will be lugging or close to it.

 

"Grind it till you find it"

 

Engine does make a difference though, especially if it's older.

 

My current Volvo with a 10 speed likes between 1500 and 1700.
Anything under that and it is lugging.
