Tonight, while 86 outside didn't feel all that bad. Went outside and cleaned out the truck, used the Tech2 to clear those antenna and actuator codes and then pulled up the tire pressures on the DIC and Tech2 and adjusted the air pressure with the Hybrid Air Compressor so that they were all the same. Before they mandated this TPMS stuff, I never never ever paid this much attention to precisely setting the air pressures before and these LT tires are extra finicky about temperature and pressure changes. Anyway, got both system to show the same number for all 4 tires. So I'm sure tomorrow morning they'll all be different again!

Checked the engine oil, not a drop lost after 3K miles. Used the Tech2 to check the Transmission Oil Life Monitor and it was at 92%.

James, tell me, do you know any other way to reset trans oil life monitor... without a tech 2? If anyone.. you would know. :)

Turn the key to the on position, but do not start. Fully depress and release the accelerator pedal 3 times within 5 seconds.

That's what's done it on most GMs since about 1995, or so.

Pete, I'm pretty sure it can only be done with a bi-directional scan tool or HP Tuners or EFI Live and such. It's barely mentioned in the shop manual and the tech who changed my fluid didn't reset it as part of the procedure.

Yeah! I was wondering that too! Did it stay pretty clear in that year? Or did it fog back up?

Mine has what looks like a clear coat coming off. When it cools off we have the Meguiar's kit to redo the GMC's and Kia's headlamps. Might just clear coat them afterwards but haven't looked into what to use yet.
