hows it going all. this weekend was the first time that i put my foot into my 71 and lets just say it beats the hell out of daily driver lol. any ways the first time had no problems at all every thing did what it was supposed to do. well i was at a dead stop and floored it got up to about 45 50 mph or 5000rpms and the engine would not shift out of first into second. i let off the gas and right after it shifted up fine. i did it again w/ the same result. it still has the stock 3 speed
tranny in it and i was wondering if i could get some hints on what it may be. well thanks for the help.
