I'm not taking sides though it might seem that way. 1st-The purchaser is very precise with telling what is wrong with the tranny. 2nd-It would be uncommon for someone to call someone out for bad dealings if they were in the wrong.(not unheard of but uncommon) 3rd-The seller says the tranny was good because he was going to use it but then he says all he knows it what he was told. No facts to back it up. Just my opinion for what its not worth.
