4.44 4EAT swap questions

[Elaine]

I have a couple of questions I couldn't find a clear answer for in all the previous threads (I'm trying to install a '97 Outback 4.44 EAT on a '92 car):
- Do I still need to use an external ATF oil filter?
- Do I need a different oil cooler or the stock one is still good enough?
Thanks in Advance,
El

1)No. LAN and I believe they restrict oil flow.
2)A different one,
(any one from Hayden/Imperial for example)
will be much less restrictive to oil flow.
BTW, when you are done with stock tires your speedometer will read about 5.5% too high.

Is it any optimum size for the Hayden/Imperial oil cooler? I remember reading that cooling the ATF oil too much is not really helping...

That is true. Really, not much actually cooling is required. You are towing zero pounds. The stock cooler has a pretty low cooling capacity. I calculated it once but i don't recall what I estimated it to be. I do recall that it would have been rated at about the gross vehicle weight. If you go with a low rated cooler, you might want to lean toward a tube and fin versus a plate style. For smaller coolers, the tube and fin are less restrictive to flow.
