wont shift

[goldie]

just rebuild my 350 trans with a 3200 stall/ rear gears 342 when i drive the car in auto it does not want to shift but when i manual shift it, its good

the vacuum line is off the modulator. or not enough vacuum going to it.

ok, what would bad seals make the trans act like. would you be able to shift it manually with bad seals? and thanks for the help!

x2 on no vacum, check the mod and the port on the manifold it may be plugged

Whatever you manifold vacuum is should be what you get at the modulator end of the vacuum line.

So if you have 16 inches of vacuum at your intake then you should have 16 inches at your modulator.

IF that doesn't make a difference try taking your modulator out and applying vacuum to it, this way you can observe the solenoid move when vacuum is applied.
