My neighbors son has a well used 99 24 v stock motor and transmission . He loves this truck. He came by today to do something ? Stayed a bit then left. When he drove down to the stop sign I could hear it start in second gear . Not first then shift to second also when he left the stop sign. I know what the problems and issues are and fixes but how long could you drive a truck like that and not know it . It’s very easy to not really notice it. I know this cause it happened to me a couple times in my years with a 99. Question is how long would /will a transmission go starting in second? I have texted his dad to call me . I think I need to tell them don’t you. If I’m wrong it’s ok but if he burns up the transmission I would feel bad not saying something right?
