On the 6-speed gearbox of Toyota Third Generation, the third generation may encounter difficulties in switching gears. Usually, the first, fourth, fifth gear and the back turn do not work well.
The most common reason for this is to plant a small leader pin in the ICP mechanism. In the course of operation the pin is gradually deformed and then breaks. It is not possible to change the transfer. The problem is removed only by the removal and disassembly of the box followed by the replacement pin.
