What happens when water gets into your transmission? Here’s why trying to flush the water out is a really bad idea. Doing that could easily do more damage than good! If you live in the Sacramento, CA area, drop in and say Hi!

Got water in your transmission? Don't try to flush it out!

I tried soaking the clutch plate in water and coolant but nothings happens.
You wouldn't really know that you are driving with water in your transmission
My problem was i had just did a trans fluid change and when I was filling the fluid some fluid got on the exhaust manifold so I took a bottled water and splashed water on the manifold so it won’t catch fire or stink bad, but some of the splashed water made its way down the filler tube. Sometimes when I check the fluid on the dipstick I see little speckles or of white. Nothing big. The vehicle is shifting nicely
I had this problem on my honda pilot. Flushed the trans. And 40k miles later it's still good. You trans shop guys are over exadurating sometimes. Plus this is vehicle specific. A pos dodge 3500 is a heavy truck and it takes a lot to move it around.
Take water and make sure transmission fluid to find a bad valve on a Chevy do it too many times
I believe that a transmission can possibly be saved if it is caught early on and properly flushed. I just recently went through this and have put 10,000 miles on my transmission so far without issue.
It happened to me before 3 years or more in nissan altima 2006 first drained coolant from radiator changed it then drain transmissiin oil refill with oil transmissiin untill its clear or better mean 2 time is ok keep car heating up then change gear after that drive car for 5 minetes all gear then go back and drain oil and refill again and take a ride so total drain refill 5 time from your first drain then refill it with oem transmissiin fluid and you are done your transmissiin will run like a champ no problem for me flushed radiator and ive added external radiator for transmission
I bought a replacement tranny for my 2002 1.8t passat and turns out I let water leak into it by not covering it a few days of when it rained an the shop said its all ruined. I m guessing they are meaning by the glue already separating from the clutch as you show on this vid but exactly how far is to far for a tranny not to be saved from water damage?
what a joke
So what do you guys do to get the water out instead of flushing it?
Hey Scotty great work. My 2003 Ram is stoked in a shop because the mechanic insist in flushing the transmission. The oil cooler went down and I had this same problem. So what you are recommending is to remove the transmission and make a deep cleaning and repair.
What causes the broplem
I've seen this myself. One other thing that is bad about this is you never get rid of all the water!!! A big percentage of it stays in the torque converter, & it also starts to rust the steel components. Best thing to do while your car is having the transmission fixed is to spend the extra money & have the specialist I.E. YOU install an external trans cooler.
Didn't really answer any questions did you?
I have attempted this, possibly ignorantly, on a 1986 Nissan Stanza station wagon with 4speed OD auto.. i flushed it with Diesel multiple times, only runing the engine slightly stationary, working all the gears and changing the diesel with fresh for each session…iv now recently switched it back to used-ATF (drained from other cars in my collection with ok/working fluid..)to flush additional water & to get the diesel out…then began driving it a mile or 3 and continuing to change the fluid for now new atf until it stops becoming dirty…the car only has 105k on it, warehoused indoors since 1999…no rust. Only paid $1k for the car and the ultimate fix is to replace the transmission, which would be fine with me converting it to a 5 speed…used transmissions for this car can be found for less than $250.. im concerned it may already be ruined, it seemed to have a lot of diesel left in it after the first time i started driving it…im seeing slight flakes of metal in the drain pan..but they may be normal…nothing is loud yet, but it shifts sloppy and clunky…the fluid is staying clean longer and i may be close to the last necessary changings.. would something this old, or Japanese be less or more likely to recover with repeated flushings?…the car was flooded, how it got water in it in the first place. wasnt driven after the flood, been restoring and fixing everything else on it. it sat for 12 whatever years and then was flooded more recently..
why is my transmission Fluid is gray in my 2007 Chevrolet Avalanche
Then what should one do after developing transmission problems due to flooding?
This exact same thing happened to my Ford Expedition. Something in the radiator (cooling tube?) wore out causing water to go into the transmission fluid and transmission fluid to go into the coolant reservoir. Because I didn't have money at the time to get it repaired I continued driving my truck and even when I finally put it in the shop it was still driving fine. Occasionally though I would notice the transmission changing gears when it wasn't supposed to but other than that it drove fine. My mechanic is currently rebuilding my tranny using brand new gears and such because I can't afford a brand new transmission plus, my truck is almost eighteen years old. I can't afford car payments plus I like my truck and want to keep it.
The mechanic has a new radiator he's going to install and he will flush everything out and put in new fluids of course. The cost is little over two grand. Cheaper than a new vehicle but imagine that the radiator caused all this damage.
I have question? My car is now on the chevy service dealer, they told me theres water on my transmission they try to flush it out and replace some expensive items such as transmission air cooling but they told me it dint work now they told thats they going to pull out my transmission to get all the water inside, is there a chance that my transmission were fucked? Becouse am scared they will tell that theu have to replace it
plastic radiators will bite you in the ass every time. aluminum radiators must be too expensive to make. Thats why the chinese radiator makers have taken over ebay with their 100$ radiators
I hate those radiators with built in transmission cooler I'm always worried that it will let go into my transmission
It's good to ask the question about water in a transmission. My Dad has a C6 Transmission it was in the car without an engine in the weather for a whole week under shade cloth. The opening at the front was not sealed and i figure currently the gearbox is stuffed. He does not believe it is, but the transmission case has turned all white from 1 week of weather a few years ago. I am not sure if i am right or wrong, but is it possible his trans with be fine? It was rebuilt prior to been put in the car. Note, Not my Dad's idea, but my Mum's brother who pushed my Dad to put it in.
And would it not be best to flush both the lines and remove the oil filter inside to release all the fluids before getting her to run again? This removes around 70% of the fluids in a tranny as about 30% are in the torque converter if i am not mistaken.
good advertisement for your business
greetings, I spend with my ford explorer, entered the transmicion water. repair the radiator. drain the oil. and I have already done 2 oil changes, but I feel the changes as heavy. improved oil color but not 100%. What do you recommend me. the model of my transmicion is 5R55S. perdo by language. I am from Venezuela
