B14 SE-L auto tranny problem
So I searched a bunch and we don't have too much info on the B14 sr20 automatic trannies. My brother has an SE-L and just this morning he drove to work almost entirely in third gear. First and second are a no go. He says he accelerated on the highway from third and occassionally it would go into overdrive. Once he let off, it would go back into third. I don't know much about these specific trannies so all I told him was to check the fluid. Do these trannies have any other known issues? Computer perhaps?
