We took our trans to a shop that promised "bench rebuild, $179," but it walked out for $210 in cash. At least they gave it three swipes of cheesy chrome paint and returned it without the spring clip on the governor cap and with a bunch of water in the pan. Lucky we found all this out by installing a B&M Racing Transpak, which is a step up from a Shift Improver Kit because it has a Competition mode with manual upshift and downshift control. We were able to clean most of the mayo out of the pan, and hopefully this cheapy TH350 will work OK. There's only one way to find out. Coming soon.
