Transmission cooler info
So I put a th 400 in my car. I have a tight 9.5 inch converter. I had mounted a 10x8 derale cooler with a fan under my car. Driver side under my seat about 1.5-2 inches off the floor. I was told it would work. For short trips my tranny never got over 180. The other night I went to a car show about 25 miles away. 1/2 way thru the trip, my temps were climbing. They peaked about 220!!
On they way home, after a few hard blasts 250-260.

I did some searching and asking. For a street car my under the floor is not the best. I just bought a tru cool 13x11 aluminum stacked cooler. They make them for b+m and they are called supercoolers for b+m. 29000 btu's.
I am trying to find a good location, I will keep you posted on how it works. There was a thread on YB about it. A guy with the same problem as me bought that cooler put it up front and his temps sit at 170.

As I understand it, the heat sink cooler suck, the best ones are stacked aluminum. A lot of guys have a fan on them too.

Best place is in front of the radiator if you can fine the room to put it there, if you can you’ll never have a problem

I have a big intercooler, might have to drop the valance panel and sneek it in there.

Not turbod here, but I run a stacked B&M cooler. I can literally drive my car for an hour straight in 95 degree Alabama heat, and the transmission only gets up to 160 degrees at most with that cooler.

Good to know, I will be testing this week!

Stacked aluminum cooler TTFMFR!

I put the tranny cooler in front of the intercooler on the r/side. I went for a 1/2 hr ride. At 1st I thought the gauge was broken. It was at 140 for 1/2 the trip driving nice. Then I was trying to get it hot to check. pulls in second, 1 full pass to 140 mph. Never got over 180.
It was a very cool night 65 degrees. If something changes in the heat I'll let you know.

100 mile ride tonight, never got over 165. I'm relieved.
