2006 trailblazer ss automatic transmission problem

The 1-2 shift solenoid valve on a Saturn Vue 3.6 is typically located in the transmission. The exact location of the solenoid valve can vary depending on the year and model of the vehicle, but it is commonly found inside the transmission's valve body. The valve body is the area of the transmission that houses the shift valves and controls the flow of transmission fluid to control the gear shifts.
It's important to note that accessing and replacing a shift solenoid valve on a transmission can be a difficult and complex task that requires special tools and knowledge. It is not recommended to attempt this repair unless you have experience working on transmissions and have the proper tools and equipment. It's also important to consult the Saturn Vue 3.6 service manual or a professional mechanic or transmission specialist to have the proper steps and safety procedures to follow.

its not easy at all I included a down load ,but you can go to auto zone web site and login and get all the directions are there (its all free ) and diagrams, to remove cat ,tranny cover and so on

Dealer or Auto Parts Store

at least in North America

Po155 refers to front oxygen sensor.

Best guess is that you have a leak in the transmission oil cooler which is located inside the radiator. It's forcing coolant into the transmission. If that's the case, it may have already damaged the transmission

not realy possible unless you put a differant seat to like an Accord in which you have to have it fitted for your SUV cause the Accord seat could be lowwer then the SUV seating it could also be just right if you are tall enough and rather larger then me to say I am 5'6" a friend of mine had a job similar done and he left the seat as is cause he is like 6'2" and works fine for his hight and wieght also the Accord seat has things that his did not like massager, heat , center back adjustment and hight adjustment

Summary: WHINE NOISE FROM REAR AXLE. *TT
I just went through the same problem with my SS. It had 3000 miles on it and it was whinning while turning either left or right. I took it to the dealer and they replaced the entire rear axle. I am not the first person that I know to have this problem. I was told that there was a problem with some of the rear ends and I have had no further problems since having mine replaced.
Thank you for using Fixya and good luck

Check the release bearing of your transmission and check the transmission oil level.

I have had a similar problem with my 06 Trailblazer SS. Took it to the dealer and apparently this is a common occurrence. They replaced my key cylinder and explained that this was because the cylinder was intermittently not completing the start circuit. It seemed to work after that. Now in the dead of winter I am having more starting issues with the vehicle.
