Transmission oil cooler

[jimsretirementf]

HI All, I have a 1989 Itasca class C motorhome, it has a 460 Ford motor with auto trans. I had the air conditioner in front evacuated and new refill fittings installed. In front of the radiator is the air conditioner coils and in front of that is the transmission oil cooler, all blocking air to the radiator. The motor gets very hot when using the air. I am looking for an remote transmission oil cooler, can anyone suggest the best one to use. I would be looking for size, cfm,cooling rows and brand. I would like to mount it under the floor close to the trans. Or is there another way to fix this problem.
Thank you for your help.
Jim

Or is there another way to fix this problem.

Just something to think about. In a way you're trying to outsmart the OEM that probably has done lots of testing to see what works best. Not saying that is bad.

When I researched mine (different model) I found out that I should get what is called a "flow test" to see if cooler is OK. Flow test measurers how restricted or plugged up your cooler might be.

However...Ford wanted about $180.00 for test (I didn't know how to do the test) A new replacement cooler with me doing the work was only little bit more. So I just replaced original cooler. Didn't have to mess with new plumbing hoses or other stuff, just replaced cooler. Fixed my problems of running OK most of time but on long upgrades my temps used to get really high.

Haven't seen him post in awhile but a retired Ford trans engineer used to comment on here. If I could think of his name you could search his postings.
