I bought one. It came as a wrecking yard th350 trans.
When I was young,on the 'hollor' we lived on there was a carryout that sold the kids pig-in-a-poke. You paid 10 cents for a tied together bag of,,,,whatever .Non-refundable.
And sometimes you got some candy,small toy,etc.,that was worth more than a dime.SOMETIMES,,,,,you were made a pig because the contents wouldn't be worth 5 cents let along 10 cents.It was indeed a gamble for a dirt poor hillbilly kid.
Enter......... ..........wrecking yard motors & trannies. Now it may be fine,don't know yet.But what would you do before installing it.Take it to a transmission shop for an inspection and get another pig-in-a-poke from their sales pitch?
