New forum user here and a somewhat new solstice owner. I’ve owned my 2008 GXP for about 2 - 3 months now and i’ve loved every second. I just wanted to know what the 4, I, L on my automatic transmission means. thanks in advance
Due to Kappa owner turnover & transmission issues I thought it would be helpful to give this answer a dedicated posting.

Q: My Solstice has a 5-speed automatic transmission with shift indicators of PRNDIL. When do I shift into 4, I or L?
A: The D position (overdrive gear) is used for most normal driving situations. It allows the transmission to shift into fifth gear, which provides the fuel-economy* advantage. The fourth postion (4) prevents the transmission from going into fifth gear. It's used for driving around town when you don't need overdrive.
The I position prevents the vehicle from shifting past third gear and should be used when driving on hilly or winding roads.
The L position prevents the transmission from shifting past second gear. It should be used only at extremely low speeds, such as in parking lots or when driving through mud or deep snow.
