Manual Shift to Neutral

The transmission manual shaft is still on the transmission and can be accessed underhood or under the vehicle body if needed to manually shift to Neutral when the engine is not running. There are two Available tools that will be released soon that can be used to manually shift the transmission to Neutral. These tools will not be designated as Essential tools.

For vehicles equipped with a 9-speed automatic transmission (9T50, 9T60 or 9T65), use the DT-52909 Manual Park Release Tool. For vehicles equipped with the 10L80 10-speed automatic transmission, use the DT-52910 Manual Park Release Tool. (Fig. 15)
