Was the tranny ever rebuilt back when you pulled it? If so, was it stored for those 2 years dry (no fluid)?
If so, the seals may have dried up during storage.
Or, if it was never rebuilt, it might be time.
the tranny has never been rebuilt it has 61000 miles on it. it was not drained while stored , but some fluid did leak out of the tail shaft during removal. it still had fluid in it at the time i replaced the filter , when i droped the pan it had fluid in it.
