Power Glide shifting question
I have a power glide, or at least that is what I believe. It has 14 bolt pan, vacume modulator on right hand side, and electronic kick down on left side (looking at it from the rear toward engine). I have read some of the other posts here and notice these things can be interesting to ID. It also has 2 gears. The electronic kick down is not attached. Doesn't look like it ever was, because the wire is more up by the coil and wouldn't reach that far down I don't think. The gas peddle has a 3 wire kick down on it. The connector on the engine wire harness is a reciever for a single blade and it's a round ( about half inch dia. just like the tranny blade reciever).
So what's my question? Why will it not stay in 2nd gear. It shifts well into 1st, and once I let off the gas it shifts into 2nd without any problem when going 15 - 25mph, but as soon as there is any minimal rev other than coasting, it wants to shift back to 1st, even at higher rpms and very little pressure. In fact once I get to about 40 mph, it won't stay in 2nd at all, presumably because the engine is reving to high, until I totally let off the gas. Then once I apply anything more than idle it instantly wants to down shift again.
I disconnected the vacume line thinking maybe it was somehow getting too much vacume, but that only made it worse.
I may need a rebild but I thought I'd see if there were any tricks out there. Other than this it opperates very smoothly, no grinding or vibrating or funny noises.Thanks for the read.
