Please Help!!
After pulling up the codes I got H72, and looked in the haynes book it says that is a Gear Selector Switch. And to fix it, it says: Check the connections at the TCC solenoid and Park Neutral Switch. Replace the ECM or repair teh transmission as needed. Ok what should be the first thing to start with? I couldnt find anything in the book about a Gear selector switch where is it at? Also it says check the connections at the TCC solenoid where is that at Im very confused right now

The 1st thing to do is get a better book than Haynes. In the future get the GM shop manual, published by Helms.

DTC 72 is for vehicle speed sensor loss. H is a history code. Suggest you drive it & see if it returns. The FSM states it may clear after cycling the ignition.
The Haynes is not worth much unfortunately.
