    4L80 gear engagement problems

    Well since my last pot went unnoticed, i was able to figure that one out. It was line pressure issues due to a clogged, (yes CLOGGED) vacuum port that somehow had gotten pinched and was nearly closed shut. rerouted the vac hose to another port and whala, solid shifts and no shudder. But NOW...

    4L80 manual shift shudder problems

    Back in June I yanked out the pcs solenoid for the trans go vacuum modulator (found it cheap on ebay). Has worked like a charm until recently. It has developed a shudder from 1st to 2nd gear. Factory diagnostic says its a line pressure issue(too low?). Gears disengage (like going into neutral)...

    tank problems and vapor lock

    On hot days (110 or hotter), the fuel in the tank starts to bubble by the time it flows thru the fuel filter (clear, ziptied in engine bay at the AC metal line). I have an inline electric fuel pump mounted in front of the rear pass. side tire. So not a mech pump issue. Also the gas seems to...

    RV cam & 502 HO head compatibility

    When i bought my C20 Burb it came with a 502 HO (confused block casting 10237300) which came up as a Gen VI. I call this "confused" as this is NOT a VI but actually a Gen V (no mech pump provision and flat tappet cam). The 502 has since been replaced by a low mileage (37k) '78 RV 454 due to...

    steering column repaired, NOW more problems

    I took apart my column to tighten those infamous torque screws that come loose. Glad i did but turns out that was only half the problem. More tightening needed at lower column area, at a later time. After putting it all back together, I have no power whatsoever when the key is turned to ACC. The...

    TH400 output shaft swapped?

    Just curious on this possibility. I had a BOP th400 back in 2013 that I sold. One day fooling around cleaning up in the garage, I took one of the spare driveshafts laying around and stuck it in the th400. Keep in mind this was a 700r4 yoke. It slid in no problem. I even put it in neutral and was...
