Driving in automatic when car is ready to shift from third to fourth gear, engine seems to go into neutral and then stays in third gear and engine light goes on.

Hi,

Since the light is coming on, the first thing that needs done is to have the computer scanned for diagnostic trouble codes. Here is a quick video that shows how it's done:

I realize most people don't own a scanner, but often times a parts store will do if free of charge. Have this done and record the codes that are found. Once you have them, let me know what they are. That will help point me in the right direction.

Take care,
Joe
