  Didn't I read where if Gm does the valve body on the "Allison", you get a 10yr/150k warranty? Kinda wish mine has a minor blip around 24k. Get a free trans service, and a pile of warranty.

  Put new plates on Pepper. I guess the state thinks ten years is long enough.

  My little joke about the check plug comes from seeing so many comments on videos or comments sections claiming that its a drain plug .... and what is actually the fill plug on the side of the transmission is the level plug. Yes, people that claimed they knew what they were doing way over filled their transmission. Indeed if I could round up the correct bung and plug setup I certainly could find a shop to tig weld it. I know those install yourself drain plug kits are available where one drills the hole through the pan and installs the assembly but it sticks up inside the pan and would not want that to interfere with the filter and it won't allow for a complete pan drain like a properly designed bung would. Oddly enough one of the main local parts suppliers no longer seems to have the Dorman pan in their system, I can only speculate that they were not selling them for the price they were charging and pulled the product, I would have to drop in and ask to see if I was curious enough about what happened with that.
