Why won't my 98 Oldsmobile 88 move in any gear?

If your 1998 Oldsmobile 88 won't move in any gear, it could be due to several issues, such as a low Transmission Fluid level, a faulty transmission, or a problem with the shift linkage. Check the transmission fluid level and condition first; if it's low or dirty, topping it off or replacing it might help. Additionally, there could be issues with the torque converter or internal transmission components. If basic checks don't resolve the problem, it may require a professional diagnosis.
