I guess my question would be why not turn the coolers over so the fan is on the top I would think the mount would give it plenty of protection.
I assume you are drawing the air from the top down as to not heat the floor?
.My engine oil system is plumbed in #10. The tranny is #8. I changed the factory tranny inlets and outlets to custom #8 inlets and outlets that are true #8 all the way through. That is almost 3 times the size of the factory fitting. In any plumbing system no matter what it is, you can only flow what your smallest fitting is.
Excellent work, it's looking good and going to work great. I agree on the smallest fitting deal, but I have a question, how did you find a fitting that goes into the trans case that does not neck down to less than a -6 AN? I could find fittings in #8 from Sweets for my 2000 model 4L80E I am putting in my car, but where the fitting actually went into the block was still a -6, so putting a -8 hose end on it was not really beneficial.
However, there is arguement that although fluid is not compressible, it can speed up in if the restriction is short and there is enough pump to push it through at the increased velocity, and there may be a pressure drop on the other side.
Anyway, just wondering if you actually found fittings that were -8 all the way through? Although the 97 and up fittings are different than the 96 and earlier 4L80E fittings.
I think DrkZides concern was something (a log or branch comes to mind) "popping" up into the floorboard and smashing it.
I actually had the same thought...
Here they are drilled painted and installed. I have the lines stubbed up getting ready to plumb them. The tranny is the smaller fittings.


It is because mine is a 91 4L80E. Mine are 2 short fittings just alike. #8 all the way through. Another trick is to use stainless fittings and drill them out. I have had to go from #10 to 3/8npt. I took a stainless 3/8NPT male to #10 male JIC and drilled it out to #10 all the way through. The stainless is strong enough that it won't break when you stand on it to tighten it. I have had aluminum fittings break if you drill them out.
Very nice work.
Can you make me some.![]()
