1998 AM General Hummer H1 - Codes P0236 & P0722
I purchased my 1998 AM General Hummer H1 a few months ago and could use some help. The check engine light turned on while getting on the freeway and got a rough kick when shifting gears. For the P0236 I found help from
P0236 Code - TheDieselGarage.com
SOLENOID, BOOST CONTROL (WASTEGATE)
As for the P0722 code all I could find was that it is the "Output Speed Sensor Circuit No Signal," anyone got any information on what this is and what I need to do to fix it. This is my first post on this website and any help is very much appreciated.

Did you resolve the PO722 code?
I’ve rebuilt the entire transmission. Boiled, new everything, I’m getting the PO722 code.
