just got back from americana at newark, (510 mile round trip and first motorway journey/big drive) and on the way home the tranny started blowing fluid from the front seal (all over my exhaust creating loads of blue smoke

). it has had a drip or two from the bell housing for a while, but it was pouring out until it it gets 1/4 inch below the min mark then stops leaking, i made a few stops on the way home topping up the trans and it kept doing this untill it finds this level, the trouble is that the level makes the gearshifts all out of sync/norm, the fluid is not burnt and the tranny works fine with the correct oil level
sounds like it needs to come out, but i want to take it to the nats as it coped with the journey easily
any ideas, or can it be fixed in place?
