That was hard to read..
Is your trans cooler clogged maybe??
What year m8?
Can also 5speed swap..if it's a 98 the trans if pretty stout with the few upgrades they did to it, so if it's an older m8 put a 98 or newer 4r70 in it.

I can't find the particular links at the moment but I think you will need to swap the internal harness, the TCC solenoid and re-pin the bulkhead connector. There's a lot of specific info over on the TCCoA site.
