Okay when I said I get 110 into drive then I put it back to park and turn off the key and watched to gauge when it is in park the pressure is at 75 so when I shut the key off it jumps to 200 before the engine comes to a stop. So what are you asking me to do?

It will jump to 200 psi when turning the engine off in park because the line. Pressure actuator looses power like when. You pull the line pressure fuse. Also I was asking if under special tests/functions on your scan tool under transmission can you buzz the transmission actuators test them audibly if there working?Also what is that 8th digit on the transmission vin really need that?

Well I tried to find the eight digit but all I could fine is what I gave you also my scanner under transmission does not have a special test button so I was not able to do the test I looked under every thing to do the test and could not find the area to the test

Iam really confused here the vin from the transmission you took out is from a 2002 single came engine. You said you have a twin cam engine that would explain the transmission issues from the transmission you removed wrong transmission. But you said when you asked your you had a 2001 SL1 that would be a single cam engine in there. Also the transmission you put in is from a 1996 car they told you it was from a 1997 twin cam engine.I dont have enough of the vin from the transmission you put in to tell you if its a single cam transmission or twin cam engine transmission. So right now we have to clear up right now what year car is this?Also what model?SL1 or SL2?What engine is in it a twin cam or dual cam engine?The twin cam engines the spark plugs face straight up the single cam engines the spark plugs face the front of the car at a angle.

Okay here is the vin of the car its self 1g8zk52751z291823 what is weird to me is that you were able to come up with the trans that I took out was from a single cam engine witch it could be because this is the third one I have put into this car. But the digit from both are the same amount of spaces so here is the numbers off the one that is in the car right now 8tz176942 the valve cover has two humps in it with the spark plugs in the middle. Witch tells me it is a dual cam motor

Alright just realized the newer vin numbers they added extra digits in the vin so the transmission you pulled out is from a 2002 car but dont have enough of the vin to tell if it was a single or dual cam transmission. Also with the transmission you just put inwith the vin numbers you gave me I can only tell its from a 1996 car not a 1997 like the supplier of the transmission told you it was from. Also third transmission thats news to me.

With the code P0732 no second gear and long delay in reverse with the pressure going right up too over 200 psi when putting it into. Reverse. You could have a leaking 2nd gear piston leaking?

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
