This is just a simple little mod that adds a 10-speed transmission to the Gavril T-Series truck. The gear ratios are taken from an Eaton Fuller, and then slightly modified. This is made for sim truckers mostly, who use a shifter with a range paddle on it, however I've been using it with a keyboard to test. The gears are a bit short for a keyboard, but I suppose it will be okay when you can give it less than 100% throttle
The range status will automatically start in high, so make sure you switch it to low before driving. This mod works best if you map the range selector to a button or switch, so that you can make seamless gear changes. I could possibly upload an 18-speed too, if anybody would like it.
To use the transmission, first you will have to go into the vehicle configuration menu, and replace the transmission to the "10-speed manual transmission". Next, replace the driveshaft with the "10-speed driveshaft", and then you're all set to drive.
The pattern goes:
