What is RPO code M-40
Hi guys ! I got the 71 GMC started yesterday, 1st time run since 06. Had to bypass fuel tank, installed new fuel pump, fuel filter 1 gallon of non-ethnol and it fired right up. No smoke no weird sounds no leaks
 My question is what trans do I have? SPID is marked M-40. When temp gauge hit half way I put it in drive and NO Nothing ? All gears BUTKUS ? WTF ? Any help would be most helpful Thanks Posted via Mobile Device
