"bought a transmission on the web" says it all. I'll bet it was an E-bay item. E-bay is notorious for sellers selling junk. It is likely that the transmission you purchased was not any good when the seller shipped it. Wish I had something positive to say.

How many miles are on this transmission? Did it come out of the same kind of vehicle ('01 Silverado, 4.3, etc.)? Compare the ID tag on both transmissions. Do they match? Is the check engine light on? HTH. -Jim

Oh boy. At the very least they should have asked for the VIN. Anyhow, yes, since the check engine light is on pull the trouble codes first. That'll point us in the right direction. See if you can get the list of RPO (Option) codes from the Chevy Dealer. You should have a sticker in the glove box with the option codes. That should tell you what transmission is supposed to be in there. HTH. -Jim

Sounds like you bought a bad trans. It has enough fluid in it? Also what kind of trans is it?
