Any differences between..

10 gears is not enough as is! Can't imagine only having 9...

 

Google your question you can find the shift pattern for most trannys. Also you should understand there's a difference between a splitter and high and low range.

 

Check the model number on the 9 speed. Some of them can be converted to a 13 speed for just a few hundred dollars.

 

The extra gear can mess you up if you are used to the other shift pattern.
And the RPM will be a bit different with the shift points.

 

Going from the 9 to the 10 may be easier. It will be like you are skipping one gear.
Just watch the RPM's and you should do fine.


Going from the 10 to the 9 is harder, because of that extra gear to the far left and down.
Just remember not to go there when you are downshifting. Stay in the middle.
