I have gone through the mcv valve. New pump,o-rings etc. I have the Blue ribbon service manual and IT manual. Measured the replacement gasket for correct thickness ready to reinstall. I made studs to help slide mcv into location. My problem is I cannot see what o-ring or o-rings are necessary between mcv and transmission housing. I have looked at the service manual several times but just can't get it. when I removed it there was one near lower left about 1" and 2 near the top at near 1/4. Could anyone give me some advice on how many there are? I do have the small spring for the steering check valve in the right location. Any help would be greatly appreciated.
