transfer case cooler A340H

Ok, nicked the hard lines with my angle grinder when I did my SAS.

I ran without the cooler for a trip and surprise, AT oil temp light came on. I was always going to replace the cooler, now I'm just doing it before the next trip.

I have the OEM cooler mounted in a safe location now, and while looking at the new hard lines and planning how to bend them, accounting for the long and not very flexible OEM lines, I thought to myself why am I trying so hard to re use the stock cooler?

So, has anyone pulled the OEM cooler and fit an aftermarket one to the transfer case? I haven't pulled the fittings off the t case yet but I will be in the next few days. Any input?

You mean transmission cooler right? There is no cooler for the transfer case. Put the biggest cooler on there that you can fit, the bigger the better.

are you sure about that on a 2nd gen 4runner?
mine has one and just about every 2nd gen auto equipped 4x4 4runner i have looked under has one.
on the A340's in early trucks and 4runners the T/C is integrated into the transmission and uses ATF instead of gear oil, hence why it has a separate cooler.

Interesting, learn something new every day. I'd still install the largest aftermarket cooler I could fit.

I should have added this in the first part, but is the stock t case cooler under more pressure than a normal trans cooler? The stock unit uses banjo bolts, and double flare hard lines. All the aftermarket ones I’m looking at are hoses with slide in barb fittings and hose clamps.

Ok. All you need to delete/replace the hardlines and extend or shorten the hoses to the transfer chain case cooler is two of these.

If you need to replace the cooler you can use these as well and not mess with the banjo bolts. I don’t know why this took me so long to find, even EVCO didn’t know what to give me. It’s just a 3/8 flare fitting with a hose barb.
