I have a 4.3 motor automatic transmission the transmission works untill I start going downhill and then the transmission acks like it is go in netural, you can downshift and it will not slow the truck down, I can give it gas and sometimes it will engage the transmission again, Once I get on level ground or up hill it starts working good again. You can go backward down a hill and it works great. You have to have really good brakes when you go down a hill. Any help thanks
have the same problem?
