So I finally got my aftermarket tranny cooler... It was smaller than I thought it would be for the GVW rating of 24,000.

It's a Tru-Cool LPD4589. (low pressure drop)
The LPD made me feel better about living in a climate with cold *** winters.

I haven't installed it yet, but I did notice something I'd like some opinions on... The instruction manual assumes there is a radiator cooler in series with this cooler. Well clearly, I've bypassed mine thus my purchase of a better aftermarket one.

Do you all think it's going to cool enough for my needs? I was really thrown off by how much smaller it is, it's an inch or two smaller than the OEM one.

 

[something else]

it may be a more efficient cooler - higher tube and fin density per area or something like that. visually compare it with the OEM cooler and see.

Why replace the OEM unit? Why not just add an electric pusher fan and a trans temp gauge. Set the fan to come on when the gauge reaches a certain temp and off when it drops down enough.

I still may add a fan. My rationalization is this for now:

From what I hear, separating the tranny's cooling system from the radiator usually in itself LOWERS the avg temp of the transmission fluid because the coolant will actually warm the transmission fluid.

When I install this thing, I'm going to put a gauge in at the same time to see what kind of temps I'm working with. Then I can always decide to put a fan in.

I know it can be a pain in the *** to find switched power though... and fans really don't do much other than when you're stopped.

I do believe the stacked plate design (my aftermarket) is more efficient, so I suppose that accounts for the size difference.
