New problem. When cold, the car starts in "park" and I can shift into reverse and the car goes backwards. When hot, the car won't start in "park", but will in neutral, and when I shift into reverse I can hear the gears engage, but nothing happens. The neutral safety switch has been replaced and re-adjusted a couple of times to no avail. The reverse issue just started. Is there a connection between the two? The transmission dipstick, if anything, reads over-filled. I'm even wondering if the folks before me put GM fluid in the transmission. It was a very VERY light pink, and very VERY thin. Any thoughts? Time for that new AOD?
