Sqaurebody pessima not working

I have an issue with the square body pessima not working. the tachometer doesn't show up on the ui for it like it doesn't have any drivetrain. yet it has a motor (which is running) and a transmission ETC. will not go into a gear nor can i see what gear it is in. the vehicle revs but does not drive at all or shift like its stuck in neutral

 

I take it by squarebody you don’t mean the Chevy trucks, but the 1988 one, do you have mods installed? Have you checked in safe mode?

 

yes i have mods, i have a mod that just released fixes and im the only one having issues. i dont know if every mod that applies to this vehicle will break it or not or if its just one singular mod thats causing the issues

 

Similar issue on the LeGran. It does seem to be affected by which transmission too.
If it has the manual, It just freely revs as if in neutral (with no tach in the bottom)
If it has the auto, it will just act like you are in drive with the brake engaged, so when you press the throttle, it revs up slightly.

 

yup
