I have 99 suburban 2500 4x4 and all of a sudden in won't go in 3rd or 4th gear it just revvs after second. And at the same time the speedometer stopped working? Please help
If it revs after second then it's usyall the 3-4 clutches are gone. It will need a rebuild. You can try to replace the vehicle speed sensor to remedy the speedo, who knows it may work. But if that doesn't then it's rebuild time
