ive been looking around at tranmission cooler and it seems like the recommended size fro teh 4l60e is Transmission Cooler (11"x6"x1-1/2") "24,000 GVW.

is there any probem with going smaller or even bigger??

 

try to stick around the 24000 GVW, higher is better IMO. A lot of people say the stacked plate design is better. I have a 26000 GVW cooler on mine it is bigger then a lot on the normal B&M coolers, but it is thinner so it fits well. I don't have the dementions in front of me but I think it was 11" X 12" X .75". It all depends on how/where you want to mount it. But I think the idea is the more the cooling capacity the better it is for the trans.

 

I think the B&M 24,000lb GVW would work fine for you. Javier97z28 has a site with a helpful install page I believe. The B&M one runs about $50 from Summit. Its kinda like a pacemaker for our always dying 4L60e's, thanks a ton GM
