the problem is that when the transmission shifts to overdrive, if the engine rpm is right, it will *bounce* from 1000 rpm to 1200 rpm. Also, it doesnt shift firm. I replaced the TCC solenoid and the trans temp sensor and change the trans fluid and filter. if i select for OD to be off, it does not do this, although the *soft shifts* continue. Im thinking it may be the overdrive selector switch, but the problem is I do not have any codes; and also the OD light in the gauge cluster is not blinking(a sign that i heard of that the OD switch may be bad.) the other problem is that when it shifts from 1st to 2nd, it seems to shift into another gear, then it will shift to third. i know it is the torque converter locking and unlocking, but if i hold the brakes, it does not do it. So does anyone have any ideas on what it may, or could be?
