Hey all, racked up some kilometres on the GQ over the last week and on the way home yesterday the auto started slipping really bad, mainly when it hit overdrive, any way it got home with overdrive disengaged. I checked the trans fluid today and it read fine on the cold level of the dipstick so I took it for a run to see if it was still slipping, it ran as normal and engaged overdrive fine, as I pulled up in the driveway I could smell the fluid and I could see it leaking underneath so I took these photo's and was wondering if anyone had some more information or advice to where it's leaking from or if its a huge job or not, any help appreciated, cheers. image (9).jpeg image (10).jpeg image (11).jpeg
I'd double check that is Tranny Fluid cobber.
From the colour, amount and where that leak is I reckon it is engine oil from the rear main engine seal... I could be wrong tho.
In regards your Tranny slipping I am not 100% familiar with the Series 1 transmission as it is diffferent to the Series 2.
Is your vehicle a Safari import or Aussie GQ... the imports are 24 volt including the electrics in the tranny.
Mine was a '94 series 2 so the switches and modes are different.
When was the auto last serviced?
How hot did the vehicle get?
If you are really lucky it may just need a flush, valve body tested and filter changes etc

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
The main shaft seal for the torque converter went on mine and it leaked out of there. But as evil said above, rear main seal of the engine will leak through the same place.
If it's trans fluid it will be leaking from the front seal where the converter goes into the pump but check your cooler lines where they go past the bell housing first to make sure they haven't worn through, if their ok then box out sorry might as well overhaul it while it out seeing it slipped in overdrive.

Hey mate, its an aussie GQ 12V, no idea when the auto was last serviced, i've only owned it for the last 2000 k's. The A/T oil temp light came on for ages (was in the line up for falls festival) and tried my best to cool it in the situation.

I see, I'm fairly certain that it's tranny fluid cause its a red colour when you can see it properly
If your A/T temp light came on it means your trans reached 140 C which is really hot for non-synthetic ATF.
Your high temp could well be the result of the slippage you mention and, if it has happened frequently, will contribute to seal failure.
Dropping the pan will tell you a few things.. If it's clean and very little material on the magnet then it was serviced not long ago. If it's sludgy and has a fair bit of metal on the magnet don't waste too much money getting it flushed because it needs to come out. There's no miracle cure..
