But on a car that shifted at 8500+ and was a 4.42 AWD these would be killer up top even at 800hp.
The 9" could be the 9 1/4" ID turbine and depending again on stator, power and shift rpm you might see a big drop in slippage.
Thick John Deere fluid can easily tighten a couple % or more depending on total slippage.

Thanks, that was a useful post. I learned something today.
If I can get the slip down to 8% that would be nice.
Got the trans out today. Hopefully the car will be running by Friday.
I bought the 8" years ago from Butler. Kinda makes me wonder about their recommendation.
I pretty much bought the PTC because Langer recommended them. That guy would know who makes a good converter for a Pontiac.
The PTC is a steel stator unit, goes for 1200$ these days.
