I have a 2000 Rodeo 3.2 L V6 4x4 with two major issues.

1. There is a gasoline smell coming from the engine when the engine is running. The smells fills the cab- it's terrible. I changed the spark plugs, and it didn't help.

2. It has trouble shifting into fourth gear. For the past few months, I'd have to get going 75-80 mph, and around 4000 rpms before it would shift into fourth gear. Lately it's not shifting into fourth gear at all. The check engine light is on, and the transmission light is blinking.

Any advice on these two issues would be much appreciated.
