Hello I have a '79 GMC Sierra c15 and it feels like it's not shifting into the last gear when I hit about 50 it feels like it should shift one more time but it doesn't and because of that I won't take it on the freeway and it runs the rpms super high, what should I do, is it gonna just blow up...- Rustybuckets69
