Its stamped somewhere on the transmission just like the engine code is stamped on the block. How do you know a JY trans will be in any better shape than what you've got?
I don't. It'll be a $100 pick-a-apart. I figured I'd check the tranny fluid black = pass and red = worth taking a risk. Rear end collision is most likely a good indicator.
I can take it out but I might pay someone to put it it ($350). So it's a $450 gamble. Local junkyard pulls all the batteries so there's no way to check the mileage. :-(
bring your own battery
Any way to turn the odometer on if there is no key?
