This mod will not work with arcade gearbox mode.
To get the rear gearbox to shift, make some bindings in the vehicle specific bindings section for shift up and shift down. These should to be different from your normal shift up and shift down
This ex driving school vehicle was picked up for cheap for the gambler 500, and an engine and transmission from a motorbike was put in the rear to make it 4wd. Homemade portal axles were welded on for some decent ground clearance.
First off a huge thanks to NOCARGO for being a huge help with the lua. the mod wouldn't have been possible without it. Also by NOCARGO is a ui app for the rear gearbox.
In this mod we have 2 completely separate drivetrains, 1 for the front wheels, one for the rear
The rear engine can be started and stopped separately to the front engine, and the rear gearbox can be shifted separately. Both use the same throttle and clutch inputs. Both can and should be used at the same time
It also includes an extra rpm needle for the rear engine
It shows half of the actual rpm, as the covet rpm gauge doesn't go up to 10k
Included is a config with regular suspension, if you want something that drives better
This mod was made for the MFD gambler challenge, and is my first mod. I'm not completely happy with it so expect some updates in the future
