I just bought an 06 silverado....multiple problems

[Derek Brock]

just bought a 2006 silverado 1500 crew cab 4x4 with a 5.3 and 4l60e, the service 4wd light is on and so is the service airbag light, just put a new transfer case shift motor in and checked the push button 4x4 switch and transfer case module, that is not the problem, the truck shifted fine when i test drove it and on the way home but when i went to drive it a couple hours later it started having a delayed shift from 1-2 and when under wot it just revs, checked a few fuses and started noticing the voltage is low, anywhere from 10 to 12.5 volts, could this all be related to an electrical problem? any ideas would help the shop i am working with hasn't looked too far into it but are guessing it is the transmission, i am not 100% convinced that is the problem considering it was fine when i test drove it

Transmission

 

Airbag light is probably front impact sensor

[Derek Brock]

yes i believe it is the front right sensor, y would the trans be fine one minute though and just start acting up?

[Daryl LBZ]

There should be another actuator on the front differential as well.

[Derek Brock]

i havent checked that yet but none of the lights on the push button switch are lighting up, they all light up on start up then turn off.

Scan it

Resolve your voltage problem first, this can screw up a lot of sensors. Clean your grounds and battery terminals including the fusible link. Maybe re-seat a few connectors like TCM and BCM. Then watch her purrrrr.

well i went to my buddys shop today and used one his techs dvom and found that my voltage is not low but my $400 doom is reading incorrectly so there went the low voltage idea... i am taking it in in the next couple days when they free up some time and letting them figure it out...thanks for the input and help

Sounds like it might need a transmission rebuild. With a couple youtube videos and some parts from ebay you could probably fix it.

If you live in the winter & salt belt, the airbag sensors could have failed. I replace mine a year or two ago. The originals appeared that they had somehow got moisture in them, which caused them to rust & freeze and fail.

 

I ended up replacing them both. I used the Dorman replacements, which I bought off either Amazon or Rock Auto. Be aware that there is a special procedure to replace them, so you don't accidently set them off.

Can't help with the transmission/4wd issues......
