I had an after market when I bought the truck and chucked the original. That being said, i never paid attention to the fact that there is a plenum that the MAF is attached to in the airbox. Mine from the junkyard was rigged with the MAF being held in place by a rubber coupling that was literally wedged into the end of the airbox......I went back to the yard and got the correct airbox this past weekend. No more lean codes, however I am still dealing with the motor stumbling when I shift to drive. It doesn't act up when the truck is cold, only when I get up to operating temperature. If anyone can explain, I need to understand what is taking place in the transmission when I shift into drive, i.e. clutch pack one is grabbing first gear, the torque converter is doing something, the accumulator springs (1-2) are doing something. If anyone can give me a general idea of what is happening, please share.

Fluid looked good and red other than some really fine dust, which I am figuring to be the clutches....man I don't know anymore. I just don't know transmissions. When it's cold it runs fine, but as it comes up to operating temperature I will get some stumbling when I am stopped. The motor runs great and the tranny goes through all the gears just fine. 1-2 seems to lag quite a bit at WOT, but under normal throttle it is great. OD works awesome too.
GO figure. It's just when you engage the tranny and it is warm, from P,R,N to D it will almost die. The hotter it is the more likely it will die.
No Codes
No blinking OD light.
WTF

I have relatives with an abundance of knowledge and tools.
I figure combined with you guys I can figure it out. It will be a great notch under my belt to rebuild that bad boy.
