What does a U1000 code mean for a 02 Chevy Trailblazer?

The error code, U1000, on a 2002 Chevrolet Trailblazer might mean that there is a communication problem with the ECM. ECM stands for Engine Control Module. Sometimes when it rains and the engine gets wet, this light will come on to tell the driver there might be a wire that got wet going to an electronic part. It will also indicate a short of some kind in the wiring so it is best to check all wire connections.

How do you find the transmission code in the vin on a 2003 Chevrolet Trailblazer?

For the 2003 MY, the 4L60E was the only transmission available. The 4L70E was only available on 2006 - 2009 models with the LS2 6.0 V8. It's not going to be found in the VIN.. what you'd be looking for would be the RPO codes. Typically, they're located on a sticker affixed to the glove compartment door, although they are sometimes located elsewhere. It'll be a series of three digit codes... "M30" indicates you have a 4L60E, "M32" indicates you have a 4L60E HD (IIRC, not available on the TrailBlazer).
