front transmission seal on 2002 Chevrolet Avalanche 2500

I have a leak at the transmission. I need to replace a front transmission seal. Can you tell me what is the estimated cost to replace the front transmission seal.

There is an estimation tool at the top of this webpage. That should steer you in the correct direction of an estimate. I know on some of the automatic chevy's you will have to remove the transmission, and then disassemble it part way to replace the seal.
