Do any of you forget to shift into 5th gear at times on the highway?


A five speed Rocket gear box is not that difficult to keep track of which gear you are in, you should have a go at a Eaton Fuller 18 speed (Road Ranger) Gearbox I never went for an imaginary 19th gear grossing 40Tonnes crawling up Queensland's Toowoomba Range working on a 500 rev Torque band,it was always a sigh of relief to see the Mobil servo at the top
 
I will send you a PM with my email addy if you can give it to him for me
 
Çusso Ken how about keeping track in an old quad box

My first "big" truck was a International Loadstar with a GM 671 and 5speed main box and 3 speed Joey box twin stick shifting was a bit of an art in itself,I leaned to twin stick shift on a B61 Mack with a quad box double declutching every change, I have driven with Spicers and Roadrangers ,but IMHO the Mack 10 speed is the easiest to use 5 low and 5 high with a flip change up or down, because of the massive torque of the thermo and Maxidyne engines you didn't need so many gears ,a bit like the rocket I reckon
 
After the retune, sometimes I skip 4th gear.
 
Been there and done that when I first got the bike. Now with ATRE-pro gear indicator, not so much.
 
I have done that. I have 2014 touring trike and done have a tack or shift gage so yes it happens no and then 55 to 65 in fourth doesn't seem to be a problem
