So I'm having some issues with swapping my old FMX transmission to an AOD from a mid-80s Thunderbird. It was a struggle getting it in and sitting pretty, but now the transission itself is acting up. I triple checked the fluid (12 qts), tried my hand at tuning the TV cable, but it just won't go into overdrive/4th.

The car has an ok time going through gears 1,2, and 3, even though it shifts at wierd times, but nothing after that.

I bought myself an oil pressure tester gauge from Harbor Freight to get the TV cable right, but once I hooked it up (using an article from Hot Rod Magazine as instructons), the gauge read 0 psi, no matter how much I shifted around and revved the engine.

I am totally at a loss. Any ideas are appreciated.
