    Help! Argh @ Transmission......

    Ok guys here's another issue with my car.. I have searched everywhere.. here and other honda sites with no luck or even a mention of my problem..

    My car all the sudden wants to keep it's self in the 3500 - 4500 range.. It used to shift fine just hard.. well now it shifts at 4500is rpm.. No matter how hard I'm on the throttle.. even normal everyday putting around.. it's roaring at 3500ish.. I'll gas on it and let off it'll shift and then be fine till I increase the throttle just a hair and bamo down shifts and is back up to 4k. Drives me totally crazy.. What could cause this?
    I've changed the TCU, shift solenoids with new oem honda ones, flushed the fluid and has dexrom III with the lubeguard modifier in it to make it compatible with honda fluid..

    What in the world would cause it to want to stay in the high rpm's? It's acting like a modulator valve gone bad on a TH350.. ANyone have any idea what in the world it could be?

        Kick down cable to tranny sticking in the sleeve? Or maybe out of adjustment?

          I had thought about that but I'm not sure on how to check the adjustment... One more thing.. I had remote start put on it saturday.. could that cause some kind of issue?

            I was thinking aboyt this and did some reading... would that keep it from shifting into 4th? or staying in the high rpms? it down shifts but it's really touchy.. I read that it needs to be adjusted to .011 THS... Just a matter of converting that to laymens terms.. I don;t have a Micrometer handy...

              K well came home for lunch.. the cable was fine but I just disconnected it to see what it would do when it wasn't connected... shifts smoother but doesn't shift till it's at 5500rpm.. and talk about a soft accelerator pedal.. I'm not sure on hot it needs to be adjusted. It's tight and has no slack.. but what happens if it's too tight?

                Ah I just said screw it and ordered a JDM tranny... That should fix it since this one has been a pain since the first day I got it...

                  dont know much about this...but I will TRY to see what I can do....you know the throttle body..that thingy that moves the flap inside there...( you know ) that thingy where the cable is on there attached to the gas pedal...anyway, that throttle thingy is probably sticking..mine was sticking badly..and my BF sprayed some PB blaster on it..and it stopped idling at 1600 and back to 800-900 where I think its normal!

                  could give it a shot...I dunno..I hope this helps!

                      Alright guys.. I replaced the Tranny, timing belt, balance belt and tensioners, every seal in the motor, got a valve job done, put on a header, adj cam gear, cleaned the hell out of the entire engine inside and out, base/cleared the valve cover, new plugs,wires, dist cap and rotor, new a/c compressor and drier, new IACV, new intake all new motor mounts, new radiator and condenser, some neuspeed sport springs and neuspeed upper tie bar, new axles, new brake rotors and pads, Fresh Z1 fluid for the tranny... yada yada.. get it all back together tonight, set the timing.... took it up the road for a spin and it SHIFTS EXACTLY LIKE IT DID B4! WTF??? Anyone have any idea? I jumped the tcu but it's not throwing any codes... I double checked the kick down adjustment and it's right on the money.. This F'N car is driving me NUTTY.......... Argh....

                        The only thing I can suggest; get rid of the automatic. Swap in a 5 speed.

                          I'd rather not.. I'm a lazy bastard. It's not a race car it's a driver. There has to be something that I'm missing.. ANyone think the TCU could cause this? Or maybe the TPS?

                            I'd check the TCU. They did come from the factory with inferior parts. There is a DIY on it.

                              I replaced the tcu a couple months ago is the issure and it shifts fine it just seems like something isn't telling it how many rpms it's at. or speed reading. the vss is new and there's no codes from the tranny or ecu coming up. I'm stumped........
