Automotive Engineers: "Hey let's put the transmission cooler inside the radiator so that if it fails the coolant can mix with the transmission fluid". Genius!
Thank you for this very well and easily explained of what is happening and the future of parts. I unfortunately have both issues. I bought a used 2005 Toyota Sequoia and now I have to get rebuild the transmission before it fails completely.
Thank you for this video, went to take my 1979 gmc for a cruise and popped the rad cap to find a pink mix , glad I found that before driving cause I have to drive to Ontario with it
I just realized, since there are transmission lines running to my radiator, then that means there is a chance that a busted radiator, could potentially mess with your transmission too.
Great video, nice work man. Helping a friend assess if she should fix coolant in trans/coolant in oil in a 200k CRV. Leaning toward letting the insurance co having the car!
Thanks for the informational video! I have a pink milkshake coming out of my 84 Chevy Caprice radiator. Thanks for the words of caution on what damage can be done to both systems.
That is a mess! Good information! TY I wouldn't recommend a trans FLUSH.... That can destroy the transmission as you know. I myself would service the transmission now, then again a few weeks later.
Hey thanks for commenting, John! Yea, I'm not a big fan of flushing the fluid either. But, concidering the factors at play, in my opinion it's best. But, I tatally understand where you are coming from. A lot of really good techs would disagree with me on some things.
On my own vehicles, I've been lucky and never had that happen although on my diesel pickup I did have an engine oil cooler fail. That took 11 flushes before I was satisfied. However, I have had my friends' bring me their cars with bad trans coolers. In only one case did I see evidence of coolant in the trans and she decided to junk that high mileage car and get a new one rather than go through the expense and headache of having the trans replaced.
I have the trans oil in my radiator but am not sure how it happened I just replaced my water pump started it up an the radiator spewed out the red stuff from the radiator cap( no leak is found)
I’ve had my radiator blow and cause my transmission to lose 4/7 gears completely. Re did the whole radiator first was flushed over 5 times and re hosed then ordered a used transmission which I’m still waiting for. Should I be doing anything else for extra safety before I get my used one installed?
Did you already flush the transmission and lines? If not, I would flush the cooler lines to the transmission to get any coolant out that may be inside them. You don't want any water in the new, "used", transmission.
Is it possible non of those options to be the cause of a bad transmission cooler could it just be clogged. Say if your line keeps popping off the same one everytime? HELLLPPPPP!!!!!
My fault and stupidity, but battery acid leaked on to my transmission and my van would not start. I used a garden hose to wash off the acid and towed it to my dealership who said the acid had burnt through some connector pins causing electrical problems, but that also my transmission had water in it and showed me a picture from the drain plug (no dip stick). The van has never been near deep water and was otherwise was driving fine before the starting issue so I am assuming I caused this with the garden hose. This was 7 days ago and the van has not been started since the hose incident. What are the chances water might have entered via a hose from the top and be visible from the drain plug so quickly? Any chance I can still flush this water and not require a rebuild? Incidentally, I frequently would long idle my van while parked. It's never overheated, but what are the chances maybe that water entered from the radiator (transmission cooler) instead and the dealership missed it? Can this be proven conclusively?
That's a pickle of a situation. I'm really not sure how to answer that safely. First, I'd say it's best to listen to the tech that has actually looked at the vehicle. I don't know if they missed anything. It's always a possibility. (we are human). But, I'm wondering how water got in. Your vent is supposed to be designed to keep water out. If the vehicle had been submerged that's one thing, but you just sprayed it. Hmm.... You could take a gamble and do a really good flush on it and find out if it needs to be rebuilt when it fails down the road. (May fail under the worst of circumstances)
@@BarboursAutoHelp Thanks. To my knowledge no pressure test done. Dealer also acknowledge chances of water from a quick hose wash off are very unlikely. they are basically saying this car must have been under water, but I know for sure it has not been. I am wondering if can get a sample of the fluid and test it.
@@BarboursAutoHelp Dealer said for sure it had no coolant in the transmission and that it's not possible in these vans.. not sure. . I just towed the van home removed the battery, the rusted out tray and cleaned it up. There is definitely water in the transmission, but I am wondering if it go in through this hole?.. it would seem so, but the the dealership did not think so.. photos.app.goo.gl/Rj5XyTb9f8QZ3cDX6
@@12vLife Holy cow! Yea, if that hole was there when you sprayed it then I'd say that's probably how it got in. lol That hole aint aposed to be there. I had no idea you had a hole in it. (I'm assuming that is the top of the trany and I'm looking into the trany at the valve body. Not sure what angle this is and I'm not that familiar with that trany.) The color of the fluid doesn't lead me to believe that coolant is in there. It looks like water. I'm so sorry, NoSunBeach. Maybe a flush and fixing the hole will get you going. Actually, If it hasn't been started you may want to start by draining the fluid first and then flushing repeatedly. You gotta fix that hole though. I hope you get around the rebuild. Good luck to you!
Accidentally put transmission fluid in my coolant reservoir. Literally thought it where you put the transmission fluid. My vehicle takes dexron 6 transmission fluid and I was low so.... And it even said dexron on the coolant reservoir cap. I put almost half a quart in. Any advice? I'm thinking about getting a coolant flush. Also wow. Who's idea was it to put transmission fluid where the dipstick is? We all learned that you don't put oil into the oil dipstick, it has its own cap you take off and fill it up in. Wow.

Darn it!
Wow, what a great communicator you are, this was very helpful
Good point , changing all the rubber stuff .
This became a very helpful video in just 1m & 27secs.. awesome!
Glad it was helpful!
This video saved me from doing head gaskets on my 3100 Buick

You are welcome

Had this happen to my 2017 Tacoma, it’s in the shop now, looks like warranty is picking it up!

Excellent information!!
great explanation. thanks
I don't normally comment on videos but great video
I appreciate that
Thank you so much! My car just had this issue, coolant mixed into the transmission....up for new transmission
This happen on my isuzu box truck, had to replace radiator and transmission . And replace both upper and lower radiator hoses.
Thanks so much! GREAT VIDEO AND INFO 🤝
Glad it was helpful!
How about If I disconnect the trans cooler and replace it with an external oil cooler?
On my own vehicles, I've been lucky and never had that happen although on my diesel pickup I did have an engine oil cooler fail. That took 11 flushes before I was satisfied.

Good to hear from you, Maingun07. Thanks for sharing your experience.
Does anyone know if there are aftermarket radiators that have solved this problem ,with better materials use?
Thanks for the knowledge
My pleasure
I have the trans oil in my radiator but am not sure how it happened I just replaced my water pump started it up an the radiator spewed out the red stuff from the radiator cap( no leak is found)
Thanks for that good explanation.
If you don't all the change outs. You just end up doing it later down the road.
thank you so much
You're welcome!

You are the man
Whats is the amount of water that got into atf is little? Will it still hv milkshake colour?

Has the dealer performed a pressure test on the cooling system. Usually if you have a leak, internally or externally, the pressure will drop.

Well, how long did you drive with it like that and did it get into the radiator?
I wish draining gas out of a car to clean it out, was as easy as draining a radiator.
did you really scratch the ford symbol off your ranger steering wheel :S
I guess the truth hurts sometimes.
