Welcome to AF.
Was any repair or work or add on stuff done before they quit?

Check all fuses for 12 violts on both sides.
Speedo/tach/some gauges and transmission are sometimes on one fuse.

yep check all that check swicth allgrounds just started one day and they did not work thanks

Did you check transmission fuse for 12 volts on both sides?
If so you have a wiring feed problem.
Transmission and tack and speedo are all on one wire/fuse.
