No if the pressures look good with the gauge if 2nd gear piston was leaking would mean the piston that engages its clutches was leaking. Inside the transmission on the input shaft you could always air check the clutches.

I posted how to air check the clutches I would concentrate on air checking the 2nd clutch and reverse servo piston. Also another thing that could cause the ratio error code could be the wrong transmission and the delay slam into reverse could be caused by not reseting the transmission adaptives after replacing the transmission.

With a tech 2 scan tool or a scan tool that can reset the adaptives not too familar with the aftermarket scan tools have only used the tech2 to reset them.I worked at the saturn dealer thats all we used that and pdt but that was only good up till 1999 I have a pdt myself.

I just see the adaptives setting the 2nd gear code though you can try it but thats all I can say. Wish I could get more of that vin on the transmission to make sure its the correct transmission.

Well I gave you all the digits that I can see in the spot you told me to look. Okay so I just did the air test when I apply air to the #2 port it is kinda slow on the movement if I put my figure on the clutches it moves great but on it own I think it should have some resistance I mean they seem loose. When I reply air to the reverse pressure to forward/reverse servo piston pressure port the frock does not move until all the 1st, 3rd, &4th oil pressure to servo is blow out then it moves with no problems.

When your putting air into the reverse servo piston your covering the other reverse servo piston with your finger correct?Because there is two reverse servo piston ports also that fork if your covering the other hole and shooting air into the other port that fork should move instantly

Okay if I put air into the reverse pressure from forward/reverse servo to 2nd clutch actuator pressure port nothing happens but if I put air to the reverse pressure to forward/reverse servo piston pressure port the fork will move after the oil pressure to servo is cleared out
