1990 Lumina APV, 3.1, 203,000 miles. I had the alternator replaced on Friday. I didn't drive on Saturday. Sunday: first gear now runs out to 5,000 rpm before shifting; second gear 3500 rpm before shifting, etc. All gears winds way out before shifting. Any relation to the alternator replacement or just coincidental? Is it worth replacing the transmission module to see if that fixes the problem? If so, where is this located on the vehicle? NOTE: The transmission shifts a bit better after the engine warms up, but still does not shift at the proper acceleration points. Any thoughts? Thanks!
have the same problem?
