What would you do? auto trans question

Oh yea, and then deal with the no KD.
You can't test a valve body unless it's in the car and running, and just so you know there are servo rings that can be changed easily by the shop if you feel you can't do it.

Also just so you know, lowering the overall pressure in the trans may very well give you kickdown back. (not a lot, maybe 5 lbs and retest)

I have a part throttle kickdown valve assembly sitting here I'm going to end up selling that came out of my 904 because the planetaries went in it so I am swapping to a 42RH OD.
The part throttle kickdown valve assembly is really easy to install also, and it not only brought my kickdown back but kickdown came in somewhat earlier than factory which was nice.
Let me know if you need it, and do some research on it in the meantime.

The shop I took it to claims they completely disassembled the trans, checked it, and re assembled. I'm guessing they put the servo pistons back in correctly. I want to pull the pan and air check the servos, but I need to know if the servo should hold air when I apply, or should I hear some leaking, even though I still see the band being applied.
and again, the shop told me that I need a one year only valve body. I believe this is false. I know the earlier ones up to 65 are different. What are the facts. From my conversation with the owner, I think he thinks it's my adjustment of the throttle pressure. I don't because when the pedal is floored, the throttle pressure lever is all the way back. Will this high pressure keep the throttle pressure from adjusting at the carb? This is part of my research, but I will need to read up on adjusting the pressure. If I can get my specific questions answered, I can move on to the next thing.
