    4l80e valve body rebuild

    yeah i've got the sure cure kit with the torlon balls, but those are smaller than the end plug ball that went missing. I only ever had 1 ball come out of my valve body, was i supposed to find two? if i buy a steel ball for a ball bearing from amazon, is it 5/16" or 3/8"? or metric?

    4l80e valve body rebuild

    lastly, the rod im pointing at was the first that got the roll pin out, and when that pin came out, the spring shot the rod right out of the bore and I didn't notice which way it was oriented when in the valve body. it's almost mirror image, with the top being a longer gap that i'm pointing at...

    4l80e valve body rebuild

    here's me holding a 4l80e afl drift in front of what i think is the afl hole, which instructions say to run the drill bit first and then the drift, and if that's done proper and cleaned the replacement is that solid silver cylinder on the right? previous sonnax toolkit owner welded a driver onto...

    4l80e direct clutch feeplay

    assembled the intermediate clutch, i have way too much room, ".140" so i added an old good condition steel ontop of the pressure plate between the snap ring and the thick pressure, this brought the clearance down to .40" pretty tight. I want to order an extra clutch and steel and have the...

    4l80e direct clutch feeplay

    edit: i found the problem, my case plug for the dual feed wasn't cut down quite short enough and holding up the center support. got the snap ring in and started working on the reverse pin length, but i've noticed once in a while my reverse band catches and seizes the rotating, most of the time...

    4l80e direct clutch feeplay

    thanks for the welcome to the forumn. yeah i need to check the inner diameter of the direct drum to look for wear. I realized on the bus ride home that maybe i forgot to press a bushing into the direct drum causing the air leak. I think i'm gonna take the top clutch steel ring that has some...

    2008 Tahoe No Start after DOD Delete

    engine computers are super picky when it comes to crank and cam signals. my buddy had stretched the wire on the crank sensor on his cavalier during an engine swap and it rang good on a meter but needed the wire replaced before the computer was happy enough to fire the spark plugs.
