    No 3 and 4 is usually the direct clutch. It could be the secondary input shaft broke or the converter stripped out but with 150 thunderous horsepower on tap, its unlikely. If it shifts into 3, its definitely not a converter, direct clutch, or input shaft problem though.

    Somehow I'm thinking valve body issue or maybe the servo is dinked. Also possible the TV pressure is jacked way the hell up, causing it to not shift. Are your other shift points very late by any chance?
    I found tons of chunks of junk in the trans pan when I swapped the linkage between it and the 89 trans that was going in.

    The link in the thread below I found to be useful for adjusting the TV pressure.

      all shift points are perfect. 1st is a bit rough but that a backpressure issue cause theres only a y-pipe dumping under the front seat at the moment. that will be fixed in the next few days. but driving it is an identical match to my 82 with the same trans. (82 is carbed though) shifts great, doesnt jerk, doesnt do anything out of the ordinary except for not going into OD at 35-40 as my other car does.

      with how smoothly it functions i was suspecting something specific to the OD. thats why i assumed valve body.

        +1 probably OD solenoid/band issues.
        No solenoids in the AOD valve body. Possibly a sticking valve or a warped valve body casting, but most likely a worn OD band.

          mechanical servo? that holds the OD band engaged

            heres a question. can the bands be adjusted like the oldschool c4?

            would a tranny flush with an aditive be a wise decision? im leaning toward no on that one.

              .
              There is a split torque path in 3rd. 40% is still through the outer shaft while 60% is through the inner with the converter locked up. OD has 100% through the inner shaft with the converter locked up. My Lentech valve body eliminates converter lockup completely in 3rd gear so 100% is through the outer shaft.

                converter lockup didn't start until the AODE. AOD does not have converter lockup, just a direct clutch further in the trans on the inner shaft.

                  Although it is technically accurate that the clutch is inside of the transmission instead of a piston and disc inside of the converter, the fact remains that only 60% of the engine torque is transmitted through the inner shaft in 3rd gear. It is not until 4th gear that 100% of the engine torque is transmitted through the inner shaft. The fact that the "lockup" is not internal to the converter is the reason that this split torque path is possible..

                    still best to clarify as "converter lockup" is a little misleading with an AOD.

                          sorry dude... you need a new OD band. I recommend a TransGo shift kit while you have valve body out.

                              I'd start with the valve body. It's easy to pull, and you can find out really quick if you have any sticking valves or crap clogging up the works. If you are doing a fluid change might as well spend the extra few bucks on gaskets.
