DoctorBill Posted July 10, 2009 Author Share Posted July 10, 2009 (edited) That looks good. Probably what I should get. I should really get around to installing one. Though my auto trans has seemed to make this far with no external cooler. I have 170k ish miles. Yes...but that is like me saying that I've made it to 66 and smoked cigars all my adult life, ate butter sandwiches, drank booze and made love to questionable women and here I am going strong.... So therefore, doing all that must be good for me. I might drop dead tomorrow morning while taking a dump. How ignominious....just imagine. BUT - if I stop all that bad stuff and repent and do only good things, I certainly will live another 30 years.... Right ! Well, the facts are that adding a cooler keeps the ATF cooler and extends the Transmission's life - so...'git 'er done ! - or do you want to buy another transmission and pay some dude $90/hour to install it ? BTW - I intend to keep smoking Cigars, drinking Beer and at least looking at and appreciating the finer aspects of the female of the species....even tho at 66 I can't do anything (as if I'd get the chance!). You put's yer money down and ya takes yer chances.....no guarantees. DoctorBill (the philosopher) PS - Do those 4 little little "stick" things they give you to "pin" the cooler to your radiator really work well? I would think the two of them vibrating would cause the Cooler to rub the radiator and eventually booger it up.

That is how the PO mounted my tranny cooler (had some adhesive cushion pads inbetween the two) and it was suprisingly effective. I hard mounted it though, just because I'm like that...

beastpath Posted July 11, 2009 Share Posted July 11, 2009 I'd be smoking a cigar, but "she who must be obeyed" won't let me smoke in the house.... do you watch Rumpole of the Bailey?? Its pretty easy doing the cooler. I mounted mine in front of the radiator with the stick mounts. I actually attached it to the A/C condensor as it has larger holes for the plastic things to go through. Plus that way I could remove the radiator if I needed without messing with the tranny cooler.

MaxRX7 Posted July 21, 2009 Share Posted July 21, 2009 wow what a thread, I like this guy and his philosopy. "finer aspects of the female of the species....even tho at 66 I can't do anything (as if I'd get the chance!" shoot you should see my dad, he is 1 or 2 years older than you, married, and still pulling the females, some in their 20s. Now I never said they are the most attractive, but not that bad either, anyways gotta give my old man props for that.

Lioncourt Posted September 16, 2014 Share Posted September 16, 2014 Anyone put 2 new coolers in line while cutting out the old one? I added a cooler and ditched the stock but under moderate highway conditions i'm still reaching 180 deg. wondering if i can piggyback another. I could go bigger but it would start to interfere with the grill I think. The new cooler is a B&M @ 13,000 BTU Link to comment Share on other sites More sharing options...
Nefarious Posted September 16, 2014 Share Posted September 16, 2014 (edited) I used a Tru cool 18 000 gvw cooler. It's physically smaller than most coolers since it's a more efficient design so fits with no problems and it has a built in bypass valve that bypasses coolant from the cooler until it reaches temp so you don't have hard shifts from over cooling when it's cold in the winter and u first fire up the truck Edited September 16, 2014 by Nefarious Link to comment Share on other sites More sharing options...
Lioncourt Posted September 16, 2014 Share Posted September 16, 2014 That one is identical to the B&M I have. Did you run in series with the stock or did you bypass the stock? What is a good temp range for these trucks? Link to comment Share on other sites More sharing options...

The new cooler is a B&M @ 13,000 BTU I started out with a smaller cooler but it was running a bit on the warm side, I'd heard of some others here using the ford explorer cooler so I added that to the other one and now it very seldom gets above 180/190 degrees Link to comment Share on other sites More sharing options...
Lioncourt Posted September 16, 2014 Share Posted September 16, 2014 so is 180 a good max target? the tunnel is still pretty hot at that point Link to comment Share on other sites More sharing options...
Precise1 Posted September 17, 2014 Share Posted September 17, 2014 180 is what the radiator cooler theoretically cools the ATF to (the temp of the radiator), but that is not necessarily the temperature that the tranny is running at. I consider 200 degrees to be the max to be running at for any extended time, that is plenty warm and any hotter and the ATF breaks down much more rapidly. One key to remember that a tranny is going to run the best/longest at a stable temperature within it's operating zone (thermal expansion and viscosity effects). Every factory mounted additional cooler I have seen (ie, tow package) were in series with the radiator cooler and almost always after it. The main reason to bypass the stock Pathfinder radiator cooler is due to clogging issues, but once that is addressed with a filter there is no harm is using it. I am convinced that the best all around, most stable set up is to run out from the tranny into a temp gauge, into a filter, into the radiator cooler, into an auxiliary cooler, back to the tranny. There are threads here discussing all of this. B Link to comment Share on other sites More sharing options...
Lioncourt Posted September 19, 2014 Share Posted September 19, 2014 I'm reading temp out of the trans so 180 out seems pretty good. will probably add the stock back in once i get some free time Link to comment Share on other sites More sharing options...
Precise1 Posted September 19, 2014 Share Posted September 19, 2014 Yep, that is perfectly acceptable, and yes, I'm in the same boat. I'm going to redo my system to re-incorporate the stock cooler as well... when I have the time. B Link to comment Share on other sites More sharing options...
