This is a non Buick question about transmission coolers.
Here's the situation: I have this 97 GMC K2500(4L80E) that the upper transmission cooler fitting(the one inside the end tank has split) is leaking pretty good. A decent to good radiator replacement is $250 to $430 depending on brand.

I thought I would just run a B&M super cooler rated at 24,000GVW that I bought in a bypass style installation. But I'm having second thoughts as to whether this would be enough cooling for a 3/4 ton that does occasionally tow 6,000lbs of car-n-trailer.

So, I have this other B&M super cooler that is rated at about 11,000GVW and is a wee bit smaller in size that is known good and clean.I was thinking that I could run them in series to add some additional cooling capacity.

Or I'm thinking wrong about this and that the big one is enough or that I can't run two coolers in series.

Thoughts and suggestions???

Had the same problem on a 98 Z71, replaced the Rad & sold. Crappy plastic Rads. :mad: Can't remember what it cost now. Descent price on Ebay tho'.
Running the 24 & 11 coolers in series should be plenty of cooling. May be too much in cold winter weather.
