This is a customized Burnside transmission I made by editing the gear ratios... This transmission setup allows the 4-speed manual to reach a top speed of 140 MPH, for racing/street use with more powerful engines. Attached is the modified JBeam file for the transmission... just replace the "burnside_transmission.jbeam" file in (\SteamLibrary\steamapps\common\BeamNG.drive\content\vehicles\Burnside). Be sure to delete the ".txt" part of the name after replacing in the Burnside vehicle folder, reload your game, and then equip the "4 MT" under the normal parts menu. Enjoy =] *make a backup of your Burnside.zip or the transmission file before replacing* i cannot be held liable for broken transmissions =3
That is not how you do mods, you should never replace original files. Use Documents\BeamNG.Drive\vehicles\Burnside folder instead. Also you can attache .jbeam attachments just fine here, no need for renaming to .txt
These might be useful at some point: https://wiki.beamng.com/Content_Creation https://www.beamng.com/threads/tutorials-index-list-of-useful-guides.51454/ I haven't checked your file, but in theory, it should work when placed in documents, although make "name" field as well as first text line different from original so it appears as new optional part in game.
