Transmission Swap Non-Tranny cooled to Tranny Cooled

Hey Tundra Fam - I have a question regarding tranny swaps.

I'm aware when swapping like for like transmissions almost all (if not all) Tundra models are compatible from 2007-2020.

I recently purchase a 2010 2WD 5.7Lfor towing and it doesn't have a factory installed transmission cooler and was wanting to upgrade the trans at time of replacement with a trans cooled version.

Has anyone swapped a factory tranny cooled version trans into a factory non-tranny cooled version Tundra?

Non-tranny cooled trans p/n: 350000C260
Tranny cooled trans p/n: 350100C260

I've called Toyo Corp, spoke with 2 local dealerships parts managers and am unable to speak to someone in back of the house at either store that can give me solid info on if these are compatible for my Tundra.

Anaya info here is appreciated.

 

The transmission cooler isn't actually part of the transmission and can be added. We have a member who sells the kits.

^^^ Agreed ^^^

No need to swap a perfectly good transmission (very expensive and involved job) when you can just install an external cooler for WAY less money.

 

My 190k trans is on its way out so a replacement is due soon, just trying to kill 2 birds with one stone.

So its safe to say both transmission, tranny cooled or non- are the same transmission?

 

Yup. You can add the cooler to either.

My recommendation: get the cooler kit, install it on the current transmission with a few drain and fills, and see where you're at. Probably cheaper to rebuild than replace as well. These transmissions can run well over 300k miles with maintenance.

 

Ohhh, well that's very different. Bummer that's it's failing @ 190K, that's not the Toyota performance I'm used to.

Don't take my word for it, but my "guess" would be they're probably the same. Some years went to an external cooler, then some through the AC condenser, but the trans doesn't know where it's going, just that it goes out one line and comes back through another. So as long as it has the valving/manifold for lines in/out you're probably good.

Then they did away with it in 2019 I discovered this a couple months ago... right after I bought a 2019

Have you priced a rebuild? Might be cheaper than replacing.

 

Current trans has endured heavy-heavy towing WITHOUT a trans cooler, its on its way out no question.

I'm replacing the tranny with a OEM trans from a salvaged Tundra, I don't want a rebuilt trans nor do i want to rebuild my current trans.

My thought process is if I am buying a new (to me) trans i may as well buy one with an OEM tranny cooler already on it rather than buy a non-tranny cooler trans and then spend extra money add a tranny cooler to that.

My ask here is more cross-fitment related, needing a more technical responder here who's swapped tranny's before and is aware of compatibility across models.

 

I'd prefer an OEM assembled and unmolested factory trans vs a rebuild.

A rebuild may be slightly less expensive but may run a higher risk of failure over the term vs an OEM tranny cooled transmission so the extra cost is justifiable for piece of mind.

 

They are identical transmissions. There's just a different puck on the side for fluid to flow to the cooler. My guess is you will still have to buy the lines and cooler. They are not part of the transmission so the parts monkey at the dealership is just seeing the part numbers for transmissions with different pucks on them, and the actual cooler us not included in that part number.

 

Do you know the history of the salvaged trans? Reason for suggesting the rebuild is that you then know what you've got, probably not as much of an issue with Toyota's cuz they're pretty bulletproof (unless you abuse them ) but many people have spent money and labor to replace with junkyard units, only to have them grenade soon after.

Most any reputable transmission shop can rebuild to OEM specs (or better if you wanna' spend the money)

The cooler isn't "on" the tranny, it's external. The only thing on the tranny is a puck with the fittings for outlet to and return lines from the cooler, so you'll have to spend extra money to add that either way.

 

This!

OP, you're going to need to purchase a "transmission thermostat" and bolt it up to the puck that your vehicle has. Then run lines from that to your cooler, that you will mount in the engine bay. Likely in front of your AC Condenser. It couldn't matter any less whether or not the transmission you're buying had a cooler installed on it or not as none of those parts will be coming with the transmission that you buy.

 

Thx for everyone input.

My ask is not pertaining an issue of adding a puck/pickup and cooler to a trans, this is a fairly simple job and especially easier with the tranny on the ground.

My ask is still as the posts subject states, transmission cross-compatibilities.

I have 2010 non-tranny cooled trans and looking to buy a 2021 tranny cooled trans, mainly to save the extra money on buying the puck/pickup and pump separately to add to a trans ($500 cost for OEM puck/pump pickup.)

If you research used tranny's they're priced the same with similar miles whether they have a tranny cooler or not so my ask is still around cross-compatibility.

I believe I've finally solved the riddle though.

I called Toyota with my VIN (2010 non-tranny cooled trans) and my buddy's VIN (2021 factory tranny cooled trans) and the part number for a replacement remanufactured trans is identical.

So in theory, I can swap my 2010 non-trans cooled tranny for a 2021 tranny cooled trans without issue. Just need to added appropriate lines/hoses and mount cooler up front to complete trans cooler setup.

A remanufactured replacement is $4500 from Toyota and on a 6+ week lead time.

I've got a line on a 2021 tranny (with factory tranny cooler) with only 4k miles for $3k, now to drop the money and put my research and theory to the test.

 

Well, the transmission cooler was discontinued on the Tundra in 2019, so your buddy's transmission isn't factory cooled.

As to the issue of compatibility, as previously stated, it's been the same transmission since 2007, so it should bolt up fine.

 

My understanding is that trans for 2wd and 4wd are different (different shaft lengths) as are the trans for the 4.6l and 5.7l (different gearings?).

 

More info on swaps please currently in the same situation.
Have a 2010 4x4 5.7 liter. Looking to purchase and install a newer trans. Been watching the auctions in area for a wrecked newer tundra. So seeing if it’s possible to use 2007 and up on my 2010 as long as it’s 4x4 as well?

 

What do you need to know? 08 to 19 should interchange with the 5.7's AB60H (H= 4x4, E = 2WD). If the tow package cooler is needed, it can be added later as it bolts on the side of the trans. On my 2010 the cooler is part of the evaporator core which is not fun to remove so, one could add their own cooler.

FWIW - The 4.6 is an A760H or E (4x4 / 2WD)
