Can you post the difference in the order of the pins or send me a link to it please?

Which route would you suggest? You would likely be the one doing the tuning. It was me that spoke to you on the phone yesterday. Would the screened 5.3 MAF have better resolution?

Given that the transmission does this whether it is in cruise control or not, I'm starting to doubt that it's the brake switch. I'm thinking that if the vehicle thinks the brakes were applied it would not only unlock the TCC but turn off the cruise control? I've read the following things...

Looking at the intake on my 08 trailblazer 4.2L engine, it appears the OEM MAF housing appears to be the choke point on the factory intake. The 5 pin connector on the MAF appears to be the same as the one on my 2003 sierra with a 5.3L. The 5.3 uses a 3" MAF housing. Has anyone successfully...

Bought the truck with about 105,000 miles. Replaced the plugs when I bought it with new AC Delco Iridium plugs. It currently has 117,000 miles. I've done basic maintenance on it since I bought it, cleaned MAF, throttle body, changed plugs, diff fluid, etc. The trans shop I took it to had...

No load was bad terminology on my part. I did not mean while coasting. I meant light, consistent throttle pressure, at constant speed, without a trailer or anything like that. It can happen whether I have the cruise control on or if I'm using my foot to maintain speed.

Thank you. I actually saw that thread before. I never noticed my TCC unlocking when I would two foot it to lightly depress the brake pedal. I'll take a look at the switch. The trans shop did say the PCM is commanding it to unlock. It being an intermittent problem makes it hard to diagnose.

I have a 2008 Trailblazer LT with a 4.2L & 4x4. I assumed this was the typical TCC bore wear, so I installed the following: Transgo SK 4l60E to eliminate PWM Sonnax Pinless accumulator pistons Torlon check ba*** New OEM separator plate Corvette Servo One bottle Lubegard Red additive. I still...

My truck had a similar issue and it was the ignition switch in the steering column going bad.
