the PCM from the buick probably has a different Trans ratio than the bonne

yup, in case you didn't already do this, I'd suggest swapping the e-prom (memcal) chip from your original pcm into the new Buick pcm.
Sounds like you are fiarly familiar with these setups so I won't explain it here. If you have questions on the swap feel free to PM/e-mail me or one of the gear-heads.

Coolers meaning tranny coolers? Shouldn't, it'* part of the radiator. how has your water temp been when your tranny was running so hot?

engine always runs cool, exactly 200 with the 195 stat, and 185 with the 180 stat

the tranny cooler is not part of the radiator, its seperate, right in front of it?

How many metal lines do you have going into the radiator? You should have the oil line and those will go out front to the seperate oil cooler, then a couple monsters for the tranny cooler (part of radiator)

The lines to the cooler in front are usually A/C

The little one in front on p/* should be an oil cooler. The bit one..but thin right behind that should be your a/c something or other...I think drier???? probably wrong. Then the radiator.

Simple way is follow your tranny lines...where do they go? I'm surely no expert yet.
