This looseness results in the transmission slipping out of gear. When the spring that holds the rail in its bore becomes weak or broken, the rail slides in its bore.

Internal shift linkage: Internal shift linkage is different than external linkage. When shift linkage becomes loose, the desired gear's synchronizer will not completely engage, allowing the transmission to jump out of gear. During this period, the transmission system will contract and freeze, causing the line fluid to sip through the seals resulting in low pressure. Most manual transmission linkage is adjusted by placing the transmission in neutral and sliding a pin or drill bit through an alignment hole. Cold weather harms a cars’ transmission system. Check these to make sure they're not rusted or binding and adjust if necessary. External transmission linkage can be cables or rods.
