I repalced the original trans with a used unit. When I put in gear nothing happens, I have checked everthing I know and the shop I got it from gave me a new trans. I put in it and nothing happens. I have checked and rechecked everthing I know. Must be something simple I am overlooking to have two units do the same thing . Any Help?

 

Did the trans come with a converter? If not i would suspect a bad converter. Did you flush the trans cooler? If not and it is plugged it will not flow. Also if you you didnt flush it well it can contaminate the new trans.
