Mercedes-Benz 600 will not go in reverse?

If a Mercedes-Benz 600 is not going in reverse, it could be due to several issues, such as a malfunctioning transmission, low Transmission Fluid, or a problem with the shift linkage. It's advisable to check the transmission fluid level and condition first, as low or dirty fluid can affect shifting. If the fluid is fine, a professional inspection may be needed to diagnose potential mechanical or electrical problems within the transmission system.
