    1992 Chevy k1500 tranny issue?

    So, last week I put a used tranny (700R4) into a 1992 chev pickup. All fluids are filled, no leaks. First time we started it up it sounded like the flywheel was grinding on the bellhousing (it is not). So there is a very loud and mechanical grinding sound and I'm not sure what the problem is...

    Question: 1993 350 TBI, what direction do you turn the distributor to advance timing? Sent from my iPhone using Tapatalk
  25. ChromedZ71

    Major misfire, all new plugs, leads, cap, rotor. Timing correct. Spider Inj suspect?

    But also, I was underneath my truck last night and noticed that there was an oil leak behind my vibration dampener. Is there a way to replace that seal without dropping the pan and pulling half my bottom end apart? Can the vibration dampener come off and the seal get pulled straight out? Sent...
