I got to take the truck out for a spin but it wont shift out of first in d or manually (reverse works). I've tried just about everything. I have vacuum at the modulator, I replaced the modulator with another I had, the kickdown solenoid (that I just replaced) clicks when supplied 12v, tried running with the kickdown solenoid unplugged all with no difference.
I did install the new kickdown solenoid using the original metal gasket which I am beginning to think I should not have used and could be my problem.
Gotta drop the pan again.
It will give me the chance to replace the leaking trans cooling line and speedometer gear. I got a deep transmission pan with a drain plug on it in case I need to go back in again.
Otherwise the motor seems to be running great.
