Hello all I’m new to the forum. I recently purchased a 2010 SE5 for my wife from rumble on. Upon delivery I took it for a ride and got a check transmission light. The light only comes on when I get on it and will immediately goes away if I shift up or down. If I keep it in that gear that the light comes on in howeverit will get stuck in that gear loose all power and eventually shut off. If I let it sit with the key off for a few minutes it goes back to normal. It seems like if I don’t get into it’s fine. I did check the oil level and it’s good. I’m new to these SE5s as I have a SM5 and any help would be greatly appreciated.

Thank you
