4.6L transmission oil blowout

Good afternoon all.
Yesterday I was on a 5 mile trip when clouds of white smoke suddenly appeared behind me. I limped to a friendly garage who found most of the transmission oil had blown out of the diptstick(no lght came on). This morning he topped up and went on a 500m test but again the oil had started heading up the dipstick tube indicating a blockage of some sort.

Does anyone have any idea whether a breather is blocked, or torque converter knackered (his suggestion) or anything else I can look at. A possible cause could have been the engine overheating on the last run out - I just forgot to check the coolant level the other day (empty) and had to run the P38 gently home in the red.

Any help would be very much appreciated!

BTW there have been no other symptons I can think of, no judder or rev spikes and the power seemed normal - i just looked behind and saw clouds of white smoke which was the oil leaking from the dipstick onto the engine!

Sounds like a breather is blocked. What year is it? I beleive there was a recall for the breather on earlier models:

Consequences: Fire.
Corrective action: The breather pipe modified. Cut and trim transmission breather hose and adjust routing.
Notif. Date: 26/02/1999
Supplier Name: LAND ROVER

PS, you shouldn't run a V8 in the red under any circumstances....they no like it.

ATF makes great :mad2: Fire! Burns easily be careful

Thank you for the reply. I think I have located the breather on top of the gearbox. I will check it in the morning. The only thing I am worried about is that it was a sudden event... With no other symptoms as though something had "gone"....

Sorry a 98 4.6l with dodgy liners

It could well have dodgy liners if it's been run in the red.
