When the car gets hot on the highway the tranny suddenly slips out of overdsrive. If I put the car in neutral ( foot off gas ) the rpm drops than put it back in drive it goes into 4th ok. Rpm at approx 2200-2400
Than maybe 20- mionutes later same thing happens. It pops out of overdrive rpm shoots up to 3500-4200. It doesn't same to happen at city speeds of 35-45mpg mostly on the highway.
