Rick, I think I saw you out at the airport yesterday! Anyway, I've got the spare valve body for you next time I see you.
Talk about a massive headache the truck has been lately! Teaches me right for swapping something when it was working fine (solenoids in the tranny). I swapped in the new valve body while breaking two bolts holding it in - hopefully there's still enough good ones holding it together.
I turned it over and it ran forwards in every gear, then I remembered I didn't connect up the manual slide valve thing, so off came the valve body again and all the check balls etc.
After getting it all back together about a third time it ran okay but harsh 1-2 changes, played with the fluid levels a bit and now it seems to be good - fingers crossed it stays that way. The fluid was dripping from the side of the pan there for a while, maybe it was spewing after running it low but not sure.
As for progress, I installed the #9 PMD but I'm not expecting any miracles.
I also got my shorter belt to remove the vacuum pump soon - maybe next month!
