So, there's a bit of backstory to this (isn't there always).
While driving on the weekend up some local trails with some mates, we came to a water crossing. I probably should have walked it, but my mate in his 80 series went through it first and it looked fine (we've got similar heights with lift and tyres etc.) I went through after him but must have picked a slightly different line as the first 10-15 meters were probably at the level of the side steps and then the bonnet briefly nosedived and went under (assuming there was a little hole in the river bed right at one side). Water came into the car through the passenger footwell (which turns out was due to the grommet on the AC overflow being flogged out) but not a hell of a lot- Probably less than a litre.
I should point out that I was in the water for a total of maybe 10-15 seconds maximum, creek crossing was probably less than 20 meters wide. My main concern is that I don't have raised breathers on anything.
Fastfoward to today, I was climbing up some pretty windy and hilly terrain at low to medium speeds (40-60kph) when my AT temp light comes on (never has before doing similar terrain). I have the Torque Pro android app installed on my phone and so I checked the temps on everything just to have a look.
During normal driving my AT temp is sitting on about 105 degrees (which seems hot?) And my engine temp is on about 90 degrees (less worried about that) as the gauge hasn't moved from the normal position of about halfish way.
EDIT: I should say that after the light came on I let the car sit for a few minutes and then the light turned off and didn't come back on- However I was careful after that to put it in Select Mode to make it stop hunting gears as much.
So, I've got a few theories about this that I'd like to float (would be really happy to hear of others though)
1) Water has turned the dust in my radiator (I live and drive on a lot of dirt roads) into mud and is causing cooling issues
2) Water has made its way through the breather of the gearbox and has borked the oil and is causing issues (really hope not).
3) Water has got into the electrics of the temp sensor and borked it.
Any ideas or suggestions are appreciated, tomorrow morning I plan to drop the drain plug out of the AT and have a gander at the colour of the oil, I had it changed about 10K ago so hopefully it's still nice. I plan on fitting breathers to gearbox/ diffs etc. before I attempt such a crossing again.
