Will GM 200r4 work with factory floor shift location?

I just measured the through hole on a standard GM (2004R, 700R4, etc) trans fitting, you know, the big one that goes directly into the transmission housing. It measured out to .230". I think this would be the maximum I would go on any part of the cooling system (as far as restrictions go). Especially knowing that you'll have a super duty pump and excellent pressure regulator. GM has used this through hole size for decades and it has never been a problem. Since the lines are .250 on GM components the engineers must have determined that .230" is the best size hole to get maximum flow without allowing so much flow that the coolant doesn't have the dwell time to cool sufficiently. With all this heavy duty/bulletproof stuff you're using you may as well put an inexpensive trans temp gauge in the car. Then you'll know for sure if you're overheating the fluid. Just follow the chart below and you'll exactly where you stand.
The chart shows how long your trans fluid will last (still be effective) relative to temperature. The gauge "sending unit' should be installed as close to the 2004R trans fluid output fitting as possible.
I plan to put one on my Barracuda before I drive around too much.
