My suburban has a 350 transmission and all of a sudden while I was driving it last night, it stopped shifting. As long as I eased on the gas pedal it would slowly gain speed topping out at about 25 mph. As I gave it gas, all the engine did was turn high rpms and the tranny did nothing, but when I let up off the gas the truck seemed to gain a bit more speed. Any ideas on why the transmission would just all of a sudden stop working?
