The purpose of this information is to provide the details of iRacing's real-world counterparts so that the cars can be driven using the same (or as close to the same) method as you would in real life. Note that some real-life vehicles may have automatic style floor-mounted shifters for which we must use one of the shifter types available to us as sim racers. For instance, users might want to use a floor-mounted stick sequential to simulate the Art Carr-Winters shifter, as found in the Pro Trucks.

How to Operate Different Shifters

Paddle Sequential Shifters

Steering wheel shifting controls found on many modern sports cars and open wheel racers. Use the right paddle for upshift and left paddle for downshifting. Cars that have a sequential transmission cannot be shifted with an H-Pattern shifter.


Stick Sequential

Functionally similar to Paddle Sequential Shifters, but mounted on a stick in the cockpit instead of on the steering wheel. Most race cars are pulled towards you for upshift and push away from you for downshift. Cars that have a sequential transmission cannot be shifted with an H-Pattern shifter.


Synchromesh H-Pattern

Your typical "stick shift" manual transmission. The timing of the shifting process in iRacing feels a little different to a real car. iRacing transmissions do not shift instantly - Your shifting inputs tell the iRacing what you're trying to do, and iRacing tries to do what you ask. When you move the shift control, you are telling iRacing that you are beginning to engage the gear, not that it has already been engaged. If you release the shift control before the shift completes, you may not have even left the current gear yet, or may end up in a neutral between the two gears.


Timing your shift by holding the clutch in until the gear completely engages before letting the clutch out may require some practice. You will often need to hold the shift control for little while as the shift goes through to completion before releasing, if you let go too early the sim will interpret that as you letting go of the shift before the shift completes, possibly leaving you hanging in neutral. If you find yourself often missing gears or being rejected from shifts, you are most likely shifting too quickly and releasing the clutch before the gear has fully engaged.


You may pre-select gears by moving the shifter into the position for the next gear before you intend to shift. The load on the transmission from the will hold the car in its current gear, and the gear change will not begin until you release load the transmission via a blip on downshift, a lift for an upshift, or press in the clutch to engage the next gear.


Dogbox H-Pattern

Similar to Synchromesh H-Pattern, except now the clutch is no longer required for downshifts or full-throttle upshifts due to the dog teeth engagement of the gears. Drivers will still need to lift partially off the throttle on upshifts and blip on downshifts. You may still pre-select gears as you would in a Synchromesh H-Pattern.


Direct Drive, Dogbox - 1 and 2 Speed

Simply select between forward and reverse gears by directly selecting the desired gear. iRacing will only allow the car to shift between forward to reverse when it is at a complete stop.
