Ok, the lowest price I found was $375 with 79,000 miles on it. I found many at the 425 to 525 range that had 40,000 to a high of 109,000. For the average price of $600.00 they seem to have pretty consistently 75,000 miles.
Some of the low mile trannys I found are, 45,000 for $725. 51,000 for $725. 39,250 for $825.
So, give me an idea of money vs miles and I will narrow it all down for you.
