Remember I mentioned I was having trouble going into 3rd at times. Now it seems every once in a while when just driving along in 3rd gear @ 25 -30 MPH really not accelerating, the car may pop out of 3rd. It only does this in 3rd no other gear. I have @ 70K on the odo. Any ideas? syncro., fork, linkage etc.? Take it back to the dealer, fluid change?
