    lock up works backwards

    The final lock up gear in my honda works backwards basically.

    When I simply cruise at 55-65 it's disengaged , when I accelerate (say from 55 to 65) it will then lock up.

    i think mine does that too, like say youre cruising along, up to speed, itll be low pitched then high pitched. then when you ease into accelerating itll jump up then down..hard to put in words, but i was wondering this the other day. Im not sure where or if there is a TCC plug that couldve been reversed with one similar.. this is in the 93 SE though

      Well at least somebody else has the same issue.I'm guessing it's some sort of sensor or adjustment because the actual converter works fine , it just doesn't know when.

        mine does it to it is normal i assure you. here is why:

        The vacuum relay valve works with the thermal vacuum valve to keep engine vacuum from reaching the low vacuum valve switch at low engine temperatures. This action prevents the clutch from engaging while the engine is still warming up. The delay valve slows the response of the low vacuum switch to changes in engine vacuum. This action prevents the low vacuum switch from causing the converter clutch to engage and disengage too rapidly. The low vacuum switch deactivates the converter clutch when engine vacuum drops to a specific low level during moderate acceleration just before a part-throttle transmission downshift. The low vacuum switch also deactivates the clutch while the vehicle is coasting because it receives no vacuum from its ported vacuum source.

          Ok that's really great but why the hell does it even exist then? lol

          I was honestly under the impression it was supposed to work as a 5th gear of sorts. So the locking gear is literally only used when accelerating in 4th gear?

            so wheres this relay valve located? Id still have to say somethings wack about the way its working (mine at least). is there a way to just disable the lockup solenoid, I dont care about OD, and usually when it starts being retarded I beat on it like a rented mule

              I'd much rather HAVE an overdrive.

              The auto trans desperately needs a 5th gear for highway driving. I'm driving at 65mph at 3000 freaken rpms. It's such a waste of fuel and so unnecessary.

              Case and point , my stick shift has a 5th gear and is 400rpm lower at 65 , and go figure it gets better mpg.

              Thats why I want this lockup to work better.

                maybe the clutches in the TC are used up from yours and previous TCM issues, mines like it slips in and out, hunting almost, till I either let off or give it some gas then itll even out its been doing it since it got it..in town below 40 im in D3 if D4 slowly I putt...Sad to see you go, but love to watch you leave..cant wait for the changeup..

                  There is a cable from the throttle to a valve arm on the transmission that affects clutch lockup. With the lever held down, the cable should have no slack. It can be adjusted a turn or two either way to the driver's preference. My EX worked backwards until I tightened it a little (if I remember correctly).

                    Thank god something to try! lol. Could you perhaps highlight that cable on the engine with ms paint maybe? or the adjustment?

                    edit: nevermind i found it , is it suppose to be very tight when in the fully down position? it has a slight wobble to the cable. would that be enough to cause the issue?

                      thanks, thats actually one of the first things I had to replace when I got the car, since the ball on the fork end rotted off or w/e and was never fixed.
                      Ill check it out in the morning.

                        Initial adjustment should be checked by having the car at full operating temp. and the throttle cable freeplay correctly set. Place one hand on the arm on the trans (circled in yellow in above pic) and with the other operate the throttle. The arm on the trans should start to move right when the engine rpms increase. Loosen the locknuts on the cable at the trans and adjust the cable length until this occurs. Test drive the car and check to see if it stays locked up at steady throttle with speeds over 45 mph.(engine at full operating temp, TC will not lock up on cold engine) Readjust if it does not. You may need to make multiple adjustments either making the cable tighter/shorter or looser/longer from the base setting to get it right.

                          It so weird , all the little bolts and everything don't even have any rust. I bet the bolts come right out without breaking off.

                            That's the kick down cable iirc

                              So will adjusting the kick down cable effect the overdrive?
