    Does Torque Converter upgrade requires a tuning?

    Hello, I'm going to upgrade to GM 300mm HP Series 6L80 Torque Converter from CircleD. Do I need to turn off lockup in PCM? Does BlackBear Traditional Tune Service include such operation? Thanks for help.

    Question about Z55

    Thanks for the feedback. The bladders on both sides are leaking. I have removed the compressor fuse a while ago. I have been thinking to replace them, but never actually did it. Now the front two also need to be replaced. It's time to do four corners. I narrow down to two options, arnott vs...

    Question about Z55

    Hello, My Z55 rear suspension are bad. The air bladder is ripped off. My understanding is that the auto leveling won't work anymore. Since the bladder is not like the air spring, is there a hydraulic shock absorber inside the bladder? If I don't care about auto leveling, can I rely on the...

    Need help debating new wheels

    I strongly agree. No chrome. Find a good shop. I have 20" chrome rims leaking at the bead. The corrosion was worse inside, also caused tiny cracks, but big enough to leak air. The rim was fixed six times at three different shops over 3 years. I always carried a pump in the truck.

    Humidity set off Traction and Stabilitrak

    I'm going to order new plug wires and coils. The plugs were changed at 80k miles (running for 20k miles). Should the plugs be replaced regardless? There is only one option for plug wires on RA, lots of choices on coils. Which coil would be recommended? Economy, Premium, Standard, High...

    Humidity set off Traction and Stabilitrak

    The Traction/StabiliTrak light came on before flash engine light. Does this still imply the the misfire may be the root cause?

    Humidity set off Traction and Stabilitrak

    Do you mean that the misfire caused Traction/StabiliTrak OFF. Will misfire happen intermittently? Will misfire happen at engine idling? Thanks for help.
