302 4v with C4. When I take off from a standstill, it should go through 1-2-3rd automatically. However it feels like it is stuck in 3rd gear from takeoff. Manually, it will go through all the gears without incedent. Please help. Thanks!
Ok, might be able to help you here. Your engine uses vacuum to determine when to shift. So first thing, make sure the vacuum line off the carburator is plugged into something and that is it not actually cracked or broken somewhere.
