Difference between BTU and GVM in Trans coolers
Since I broke 4 trannys, I installed a B&M Supercooler 70268 in the box said 13,000 BTU, here in forum, I see the 24K GVM, but in the B&M models, didnt see that number, then I see that is a different concept.
I have right now, that cooler and a deep oil pan with ventilation, I dont want to broke again the tranny so I was thinkin in install a 2nd cooler but I dont know if there´s better to install only one but bigger or install a 2nd.

I would get a larger cooler and go with one instead of running two. What are your trans temps?

I really dont know because dont have how check it, I remember that the friend who sold me the tranny, told me that never is higher than 160 with supercooler by 15,000BTUS and deep oil pan

Trans temps can go above 160 and usually do. Motor temperatures are usually at 160 with a T state. But trans temps can go over 200 degress without problems. A trans cooler that is most suited for Camaro's Pontiacs are 3600 GVW. The smaller coolers will help out but they arent suited to handle this size car.

Engineers use this to size everything that transfers heat like radiators, a/c condensers, trans coolers.
It would be easier to go by GVW, this way it's already been figured into the size of the cooler.

I don't think the two have a conversion.

That´s my doubt, because B&M only use BTU´s.
In one of the models, could see that the one that said 13,000BTU, have the GVM term and said 19,000GVM
So "MAYBE" if you said that our FBody need 36000GVM, the sticker of B&M must be of 24,631 BTU??
So, the guys that use the 24,000GVM, use the model of B&M of 16.421 Btu?
The models are
70255 12,000 BTU
70268 13,000 BTU
70264 14,400 BTU
70273 15,000 BTU
70266 20,500 BTU
70274 29,200 BTU
SO, I´m using 70268 and deep vented pan, and dont have converter.
Would be better to install other 70268 or 70273 so have two?, or install only 70266, or leave the one I use?.

bypass it, its a restriction. There really is no need to keep your stock cooler, unless you live with snow on the ground 9 months out of the year.
