hi i’m 15 and have been working on my truck for quite a while now and i’ve found myself in a position where i don’t know where to go
my sierra has a newer engine and has been sitting for 5 or so years the transmission decided that it with run and drive off startup but once you stop at a sign or light it will not go just will rev to the limiter also the shifter will not go in any other gear unless the truck is turned off and had a second to cool down. i believe its a th400 but dose anyone know what could possibly be wrong?
