Picking up a Haynes manual today on the drive home. My friend's tech2 had to be sent in to be fixed, so waiting on that to come back and we will dive into some trouble shooting. Anyway to do the Transmission Adaptive Pressure reset without a scantool? Or to find the pressures without a scan tool?

Not sure. Found a youtube video showing how to reset, but looks like they’re using bi-directional scan tool. I was able to buy used vxdiag on ebay.

Need the Tech-2 or other bi-directional scan tool to do that stuff.

Alright, got the subscription to AllData, now where can I find the pressures? I’ve been digging around for a few days and cannot find that specific info. I did see a YouTube video that said anything over 12 was high, but that’s about all I’ve found so far.

You talking about the pressures in the manual or in the Tech-2?

I could not find them in the Haynes manual or the alldata website. Haven’t gotten with my buddy to look at the pressures with the tech2. Night be able to this weekend, but need to find a new car for the wife on Saturday.

Can't remember where either. Just did some looking on AllData and my shop manual but my eyes are shot. Need to get off the computer.

I can relate. I spend most of my day at a computer reading emails and building reports and dashboards!

Ran the Tech-2 today on the highway and in town some to look at transmission pressures. Pressures are 109 psi as it switches on and off solenoids 2 through 5. The ones for the converter are about 13 for one and variable for another, more when the torque converter is unlocked and slipping.

Took two snapshots and uploaded them to the laptop. After Bible Study, we'll record and upload one to youtube.

Any of you Tech-2 guys with 6-speeds remember what your pressures are? @gooffeyguy @Doubeleive
