Shifter Roll Pin Issue

Some owners of 2005-2010 Chevy Cobalt vehicles have complained about hop-out or blocked shift of 1st, 3rd and 5th gears or difficulty shifting the Getrag manual transmission. The shift lever roll pin can back out and contact the shift cover during a shift event. This can cause an incomplete or blocked shift or shifting difficulty.

Prior to any internal transmission repairs, inspect the shift cover and lever to see if the roll pin has backed out and is dragging on or contacting the housing. If roll pin contact is evident, the shifting difficulty may not be an internal transmission concern.

If the shift cover shows witness marks from roll pin contact, replace the complete shift cover assembly.
