I'm down in Australia & looking for information on an upgrade for the wallet size standard transmission cooler. Any help will be appreciated.
Almost forgot if I would change anything about my cooler install. I would and will (at some point) add a bypass valve to skip the radiator and go directly to the cooler. Going through the radiator then cooler is great in the winter to help get the trans up to temp but, in the summer only adds unwanted heat to the system as I see it.
Can you expand on this? All my e4 and 4r trucks do the opposite, the trans heats up much after the engine. I’ve also got a customer truck here with a transdapt deep pan and that truck will take half an hour to heat up the trans.You have this backwards. First the radiator never heats the tranny fluid. It cools the fluid.even in extreme cold the tranny will heat up faster than the radiator. Remember O/W coolers are the most efficient type of cooler. This is why it is a primary cooler and never should be bypassed.
Now the aux cooler should have a thermal bypass for extreme cold.
How many of them are you actually watching both temps? For all that goes all 3? (coolant, oil, trans)Can you expand on this?

All of them I have coolant and trans temp reading at the same time, in the 6.0 trans always warmed up before the engine after the delete till it burned down. The deep pan is on a customer truck not mine, we put it on mostly so it had a drain and for the built in cooler. I’m not sold on aftermarket trans pans either, just like aftermarket diff covers I really don’t think they do much for performance or cooling.How many of them are you actually watching both temps?

In the 03 6.0, trans temp is always first to come up.
That deep pan does nothing for "performance." Nor cooler temps. Takes longer to heat up, as well as longer to cool off.

I'm not sure. I just know what I see on a daily basis.
