Driver fm380 - Panasonic KX-FM131 Fax

Hi, I take it that this is a Manual transmission.
Check the following: Oil level, Linkage to the selector {if its loose or not} And at the linkage if any wire or cable is obstructing it.
If it pops out of gear when you coast {releasing the acc when in gear} This can mean that the gearbox needs to be stripped and gears need to be replaced.

According to the Panasonic global website, they stopped support of drivers at Windows 7. There never was any 64-bit driver support for this device, only 32-bit.

What help do you need?
