This is pretty much a no brainer. Transmission cooler section inside your radiator is bad or you have tried to cross a flooded creek with 3' of water.
change the fluid after finding where the water comes from water will cause rust in the transmission if left in
I can't see any reason for water to get in the transmission unless it went under water from a flood or crossing a stream. If engine coolant is getting into the transmission I would blame the transmission oil cooler in the radiator in which case the radiator would need replacement and the transmission flushed professionally. If the vehicle was driven with coolant mixed in with the transmission fluid you will probably have transmission failure before long.
Failed radiator transmission cooler.
Yes water cause leaking
Yes, water can enter the automatic transmission during high water crossings if the transmission vent is submerged or damaged. This can cause damage to the transmission components and lead to problems with shifting and overall performance. It's always best to avoid driving through water that is deep enough to submerge vital vehicle components.
ofcourse
Waterborne transmission is when a disease or infection is transmitted to a person by water. The water must be contaminated in order to transmit a infectious microorganism.
If you are asking about flood water, yes. All transmissions have a vent to release excessive air pressure that occurs from normal heat build up. If the water reaches the level of the vent, usually at the top most of the transmission, then water can enter the transmission.
a categoric "no."
bad seal, the transmission is under your car by the road itself, if the seals are bad, water dirt and other debry and can penetrate (bad)
The Jeep could have been through deep water that was over the transmission height without the breather lines extended.
It will be a PINK color when it should be a pretty RED color. You will have to have the transmission flushed out at a transmission shop and the fluid and filter changed too. Then you need to find out HOW the water got in it in the first place.
