Hi I have a issue with tachometer the rpm works fine but everything else doesn’t work even the change gears can someone tell me what’s wrong

 

The tachometer is the RPM gauge. Not exactly sure what is not working. Can you explain more?

 

So I had this issue after my Transmission got worked on and it turned out to be a cable with a bolt connected to the transmission was loose and dangling. Look underneath on driver side kind of near the backside of the transmission see of it is loose or completely off. I hope this helps!
