Not sure if anyone here can comment on this but I thought I'd give it a shot...
About 6 months and 1000 miles ago I put a used '99 4L80E in my '93 1-ton hay hauler (it replaced an early type 4L80E - I bought the harness adaptor etc...). Tranny shifted fine - seemed happy - had not had an issue - until now.
Well - my wife called me from the feed store a few days ago and said that the truck was smoking. I get down there and it has burped perhaps a quart of ATF out of the filler tube (enough that there was a puddle in the recess of the air cleaner lid). I followed the trail back and it looked like this had happened just a few feet short of where she parked. I checked the fluid level and it is quite low.
I figured that if it was dead - it was dead - so I limped it home - and it acted fine...
When I swapped the tranny I paid a friend who was out of work to do the swap (he is a good shade-tree mechanic guy on the side). I asked him if he had somehow swapped the dip-sticks and he sure that he did not - the stick and filler tube that came with the replacement tranny are the ones in use.
Can you guys think of any scenario in which this would occur and I do not have impending tranny failure?
