stupid trans cant make up mind

[madhat]

Sometimes when I am just slowly getting up to speed, or even just cruising just before the shift to 3rd, my trans will start shifting between 3rd and 2nd until I speed up a bit and then it will go ahead and shift to 3rd. Never does it any other time than really light throttle situations...I started noticing it after I put a new servo in. Is the servo causing this?

Same thing here, try moving your TV a click one way or the other.

I ordered a new TV cable from GM(broke my old one) and it is a slightly diff design than my old one(now has lots of little teeth n sounds like zip tie if you move it real fast) and if I move it even one click more it will start shifting(light throttle) @ 3000 out of 1st and upwards of 4000 for second(never got it to shift out of 2nd and went up to 4200rpms)
