HELP! Why can I only get to 25 mph in top gear?

[RedFreakonomist]

Hey all, I'm pretty ignorant to trucking in general and I imagine i'm doing something foolish, but here goes:

speed limiter and auto retarder are both off, using a 10 speed H shifter configuration.
in 6th I can achieve a top speed of 10 mph. I'm flooring this thing. Once in 10th, which the truck barely sustains, it tops out at 25 mph. What is going on here? Anyone have any idea what I'm not doing?

Thank you all for any assistance.

Are you just jumping straight to the higher gears or are you allowing the speed to build up in the lower gears 1st?

As dumb as it sounds, try parking turn engine off, then turn it back on.

Usually whenever that happens to me it fixes it. Otherwise i just restart the game.

It helps to know how to use a manual clutch system.
Trucks also vary on shifting based on load and engine power...

Check in your control config that you aren't activating the brakes....in other words, that you have enough of a deadspot. Not sure what controller you are using as it isn't listed.

Go into options, then controls.... Scroll down to shifter layout and make sure it matches what you are using

^ I would say this is the most likely candidate for your problem. You need to manually change the shifter layout in the 'options-->controls' menu anytime you're using a different transmission. It's right down near the bottom of the controls page.

If the truck you're currently driving has a ten speed gearbox, you need to set the 'Shifter-layout' option to a matching layout from the drop-down box. If the truck doesn't have a ten speed and you're using the ten speed layout, then what you're seeing would be consistent with that situation.

Check the diagnostics page to see the installed transmission of the currently driven truck.
