    Yeah, I figure I'll just snug them up tight. I am planning on getting the cooler installed the following Monday after Christmas.

    Looking at the pics of the warmer/cooler and the thermostat again. Is it simply the o rings on the warmer squeezing against the thermostat body that stops cross contamination of coolant and trans fluid?

    From what I understand the warmer is just a closed system that acts as a warming plate. The o-rings are for the spacer or cooler assembly.

    Yeah sounds more likely, hard to imagine just a couple o rings doing the job, lol. Anyways I'm closely watching your progress and will likely be following suit as I use my Tundra for a decent amount of towing but only put on 5-7k a yr and planned on keeping this for a fair while. Traded my 08 in and never gave a second thought about no flippin external cooler, guess you can't take anything for granted these days.

    Made it back home. The mount came out perfect. Now just waiting on the stainless hardware to arrive to bolt it on.

    @Roman do you happen to know the part number for these zip ties? I am going to use them to secure my transmission line since the same size oval holes are on the frame. The second picture is the hole its self its 1/4" x 1/2".

    Quick question, hope you might know. When I remove the warmer and spacer plate, will ATF start spilling out? If so, how much do you think? If it will spill out a bunch of ATF I'm thinking of just jacking up the right side of the truck to shift all the fluid to the left side.

    Some. Probably less than a quart. The ATF won't be under pump pressure, and you're talking only about passage and cavity volumes higher than the side openings. The real volume in the converter is pretty much trapped.

    In your position, I would forget about trying to jack up the right side higher than the left to prevent ATF leaking out. Whatever that volume is; it is what it is. ATF is cheap compared to your safety. You may need to jack the truck up, and place jackstands on four corners just to get working room (Don't do this unless you need to; working under a raised vehicle is risky enough without jackstands.) Jacking one side higher than the other, especially while using jackstands, is the perfect recipe to get you squashed like a bug. :eek:

    Okay, if it's less than a quart I will be good. I have 4 quarts on hand to fill the cooler, hose, and whatever I lose from taking off the plate. Thanks for your help.

    I said maybe less than a quart, but I have absolutely no way of knowing. Buy 20% to 30% more fluid than you think you'll need. If you have some left over, you can always use it for "drain and fill" maintenance.

    Hmmm. I might just jack the side up so I don't lose more than I have. I have 6-ton jack stands that will be more than safe. Plus, the truck only have 1900 miles on it, no need to lose fluid if it is preventable.

    The issue is NOT the capacity of the jackstands. The problem is the stability of jack stands with the contact patch potentially angled or sloped, potential contact area reduction, unstable platform, etc. If you don't have enough experience to make a good assessment, you could injure or kill yourself.

    For the safety of you and your Tundra, my advice once more before you begin is that you should pay someone to install this cooler for you. Take your Tundra and the parts you've acquired to an RV store/shop and get a quote for the installation labor.

    It is honestly not that hard. If you use the frame and have double redundancy it's not an issue. I will not pay someone to do this when I have all the tools needed and common sense.

    Maybe get some ramps instead of jack stands and just drive the passenger side front and rear up on them. Seems safer as long as you chalk it so it doesn’t roll.

    I’m always worried every time I work under a jacked up vehicle.

    "Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don't know we don't know. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones."

    With what's at stake here, I would consider "overthinking it" a good thing, but's thats just me.

    Got the spacer removed and the cooler installed. Only lost ATF that was in the warmer. Now, just waiting for my final revision of my cooler radiator mount to come in on Tuesday and will get everything buttoned up.

    Did you notice if the spacer orings were the same size as the ones that came with cooler plate? Thinking about picking up some spare orings incase one gets pinched, but if the spacer ones are the same size then I wont bother.

    The spacer o-rings are the same size. The cooler I bought came with the o-rings on it so the ones in the photo are extras.

    How tight did you go with the warmer/thermostat bolts when you reassembled?

    I just snugged them then put maybe a 8th of a turn. We will see if it leaks when I get everything hooked up.

    Yeah, they're squeezing o- rings so good and snug is likely enough.

    Trying to slow myself down, lol, -30 here so gonna be awhile till I attempt this.

    Lol. Yeah I'm sure your transmission doesn't need a cooler right now.
