No Second Gear - 700R4
Ok, I've been having an issue for the last week. I have a 700R4 auto and it shifts fine in any gear other than 2nd. If I drive with overdrive enabled the revs climb in first well past the regular shift point and then the revs fall to where third gear should be. It doesnt slip, but completely skips 2nd. If I manually step through the gears, 1st and drive are fine but in 2nd it just races, like the transmission is in neutral. So, basically no second gear. No slippage in other gears through. I pulled the pan and found a small screw that had been caught by the pan debris magnet, but other than that the fluid looked great.
Could this be a valve body or control problem? Or a broken band? I'm hoping it's some sort of control issue and not something where it needs to be torn into.
