    I’m surprised no one has added a b&m tranny pan, It adds an additional 3.5qts capacity...

    Does it make a significant difference in temperature though? Pretty expensive to find out.

    Nice! Looks like your new mount is in a different position than at first. Any chance of a pic w/o the grill?

    Wouldn’t think so as the transmission temp is going to generally follow the temp of the coolant with this set up, right? It might take a bit longer to get additional fluid up to the “designed” operating temp but once it’s there it *should* be pretty stable unless you’re really pulling up a hill. But it’s probably going to average 220ish all the time with the factory set up regardless.

    This is a picture I took last night so not the best quality. The cooler is not tightened all the way so its sagging a little bit. I am now just waiting on 45° adaptors to come in the mail to hook up the hose and fill the tranny with ATF with a level check. I am trying to complete this project as soon as the adaptors come in then I will see if there is any interest in folks buying the mount I designed.

    Did you end up running hose all the way from the trans thermostat to the cooler or did you use the oem metal lines as well?
    Cooler design change, just using the three tapped areas to mount it?

    I haven't ran hose yet. I need to wait until the adapters come in then drill holes and put grommets on the air deflector. I will have everything done here in a few days.

    I see many trans coolers have what they call "cold weather bypss" that redirects thicker trans fluid back to the transmission until it warms up. Is a type of cooler like this necessary seeing as we also have the warmer?

    On the other hand I guess the thermostat kind of controls flow regardless.

    The thermostat will control the fluid going to the cooler. If the atf is not 190-200 degrees the thermostat won't open.

    The warmer will warm the atf until it it reaches that point, then the warmer gets cut off.

    Double clamped? Different than the warmer clamps.
    So did the spacer removal and thermostat addition go well, any difficulties?

    Put the double just in case. It is almost impossible to put the clamps on when the cooler is installed so you have to clamp the hose while the cooler is dangling then install.

    I have to ask, did you use trans cooler hose and not fuel line hose?

    Impossible? You mean where you double clamped the thermostat or was it the cooler up front that was difficult to clamp?

    It's a tight space. I was not able to get the hose on the barbs while it was installed.

    LOL! Completely off topic and random, but I started cracking up when I read this. For 30 years I thought “nip it in the butt” as well. Never thought twice about it .
    One day I googled it, and found out the correct terminology is “nip it in the bud”. As in cutting off the growth of a plant - or stopping something.
    Just thought I’d mention it. LMAO!

    AN and JIC are NOT the same (.5* difference in taper) but are interchangeable.

    Just for people searching in the future.

    They are 10 AN fittings with O-Ring. I know because that's what I have installed.

    I wasn't disputing that, you're correct, that's what they are. I didn't say they weren't.

    I actually quoted the wrong guy, he said AN and JIC are the same. While they do interchange, they are not the same.

    this is ODD...
    just stumbled on this thread and it's kinda hard to believe that I don't have a transmission cooler...

    the REASON I find it hard is my 'purchase sticker' from the truck the day i bought it says...
    So, does my 2019 SR5 with Tow Package have a trans cooler or not??

    Looking through this thread, and seeing pictures, and checking my truck... I have the round body with two hoses going to the "Trans cooler" on the Pas Side of trans, but not the "Thermostat Unit"... that goes between trans and cooler...

    so I def have a trans cooler... but how does it work? what is being sent into the the trans cooler? is that water? or is trans fluid being sent out?

    Just try'n to learn something new...
