How to tell if you have water or antifreeze in your transmission.

Among issues that an automatic transmission can have water or antifreeze contamination is certainly a concern. Whether due to a damaged radiator tank, improper under hood water drainage or exposure to flooding it is imperative to prevent and if needed to rectify. If called for testing should be done.

Please comment on glycol used as a tooling wash at transmission assembly. Glycol found in ATF fluid after oil analysis 24k kms. Transmission has its own cooler and not within radiator.

Another one of these long winded answers just got to the point we all know that water is bad for a transmission. Holy crap.

In a car with dipstick standing in high water without starting up the car after water exposure . How can you take out some transmission fluid to test and see if water seeped in without taking off the oil pan or must the oil pan be removed to get a sample a but after you’ve done that, might as well change the fluid as a precaution.

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 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 instead and the dealership missed it? Can this be proven conclusively?
