I just found a B&M transmission pan for the 4R70W. It's aluminum with the cooling fins along the bottom and holds 3 extra quarts!!! This is probably a dumb question but would this be a good investment worth the money??

I don't do alot (hardly any) towing but my concern on trans temps is when the converter unlocks (or locks if I got it backwards) going down the highway. It's really windy where I live and not uncommon to drive around like that for several miles. I couldn't believe what that caused after I got a temp gauge...WOW. Anyway, would like to help battle that some but didn't really have a need to change the coolers and all that.

 

Its a good question and one i dont have the answer for but would be interested in it anyway. I guess where I sit Im expecting a short life from my 4R70W since my truck is blown and when it goes I will get one built to handle the power. This question may get a better answer in the tranny forum.
