Was there an option on any of the same chassis from GM with an option for a Trans Temp Guage in the cluster ?
Will a cluster from a 2500 or 3500 series Pickup truck be the same for fit & harness connection?
I had a 2001 Yukon 1500 series and bought a cluster from a 2500 series (it fit both GM SUV's & Pickups, that had the HD tow package and the trans temp guage was built in. it was a 5 minute swap out and Plug & play.
I also had a scan guage plugged into the OBD port for added information.
I no longer have the Yukon But still use the same Scangage in my 2006 Ford E350 Motorhome and Trans Temp is one of the 4 dispalys i use all the time.
