Question. To anyone who also uses the Logitech G25, pedals and stick shift - did you have any problems getting the shift to work in manual H box mode? Mine only seems to like working in automatic, which defeats the point really as I got the rig primarily to enable the use of a realist clutch and stick shift while racing & to keep my real-world driving skills in practice as I haven't owned a car for 12 years now but may want to again soon.
Do you mean when incar you press accelerator and the gears change themselves, or that the H shifter only moves forwards - backwards to shift up or down gears?
Also what game is it?
If its shifting with accelerator usually the game is set for auto gears, turning this off in options should do it.
If its the fwds-bckwds then put shifter in neutral and press down on the top of it whislt turning the dial just infront of the stick 180 degress to the right. Shifter should now be in H mode.
However you usually need to tell the game what gears to assign to the H shifter pattern by assigning them yourself.
GTR2 I think has a default setup for the G25 which should work from default, if you are'nt using auto gears and have'nt assigned a gear up gear down setup ie using the paddles on the wheel to shift.
(You may need to toggle hold button down for gear change in the options if it acts strange)
I should mention to add mods/tracks to GTR2 you will have to download and install them yourself, but there are more than enough tracks and cars in the basic game itself.
