I tore this trans apart today and had to do a double take and look over it a while. It was from an 00 Monte Carlo and never been apart before so this happened straight from the factory. There is a solenoid retaining clip STUCK on the end of the afl valve which is viewable on the back side of the channel plate. This clip has no business being here and because of its location when bolted into the case was in a casting area not accessable unless the channel plate is removed. I have no idea how something like this got overlooked but Im sure caused a world of problems and if it ever went back to the dealer I bet they were lost! The clip had been clearly been there since day one because of the impressions it left and how the debris settled around it and it was clean under the clip where it was laying. It was holding the afl valve open a little bit and when this valve sticks it can cause slippage and 2nd gear starts. I bet this trans worked like a dream!
