    Ok, so there must be something else going on. I noticed that if it changes to 4th between 60 - 70 km then it tend to surge. But not as much since I have changed the fluid. ( need to change it again anyway as I put the RTK2 filter in instead of the RTK4. So that is slated for Monday morning.)

    If I stick the boot in to it, it seems to change as normal, for example merging on to the Motorway. Probably more noticeable driving up a steep incline.
    It is only the 3-4 gear change. Other gear changes seem normal.
    Is it the Torque converter? or something else to do with letting the transmission know the output of the engine? It is idling a bit rough. So maybe something there?

    When I look at Envyous software AED (Advanced Engine Diagnostics) nothing, from a layman point of view, stands out.
    I can post screen captures if someone wants to look at something specific.

    What book do I need to buy/find to understand the different parameters from the AED software?

    For example the Parameter: 3-4 Adaptive pressure = 32 psi
    I would guess that it should be higher if the torque converter was faulty????

    Or am I completely off the track?

    If its surging I say it be one of your shift solenoids,

    Thanks mate, I appreciate your help.
    The problems is that I am not getting any error codes on the dash. And when I do a read with the AED software I don't get any errors.
    So if the 3-4 clutch was about to crap itself, would it throw an error code?

    I'm going to have to buy those solenoids as I don't want to find out that they are faulty with the pan off the transmission, as it is a 45 min drive each way to get new ones. So I'll change the fluid once I have the solenoids.

    Like the guy said in the video you may not need to replace them, I suppose if they will give you a refund it wont hurt just in case, wont hurt to pull out the valves to see if they not blocking up. Good luck. Oh you did replace the seal on filter yeah, its important that its not sucking air. The guy in the video shows how to replace it and also don't damage the wall any scratchers will create a vacuum leak.

    I checked the filter seal when I changed the filter last. It felt firm when I put the new (wrong) filter in. So I would imagine that it is ok. those valves seem like a good place for things to be "gummed up". I am apprehensive about removing those clips off the solenoids as plastic get real brittle over time. And it would be a real pain if I broke those clips.
    Thanks again.

    Your problem is the blind leading the blind.

    That's fine, but I am not working, so at the moment I don't have the $800 (parts and labour) to use a swap-over from the wreckers, and I don't have the $1400 for a transmission rebuild.

    So what is your opinion?

    Quick google search says 1st gear shift solenoid A and B are on, and in 3rd gear A and B are off so there for they are working, another search shows 4l60e surging worn TCC valve or clutch in converter.

    To get the fault codes you need a special scanner for transmission, blind leading the blind pmsl, the videos show most of the details, also is it the transmission surging all the engine it self? Why not just take it to a trans place to have it tested and see what they say before spending any more on parts.

    Solenoids are $45 a pair for AC Delco ones, so cheap enough to throw in, but i doubt it will fix your problem.

    U can pick up a secondhand tranny for under $200, just find one that hasn't done to many km. I be getting the original tested first from a transmission place first it may not be the tranny but the engine.

    Well that's a special tool you tool. Without the proper ADX file you cant get the codes, its not called a tech 2 tool for nothing, they also test PSI pressure.

    4l60e's don't have a built in oil pressure sensor, that's why they have a test port.

    Hmm $800 tech2 or a $80 ALDL cable now who's the tool.

    Get the right filter in it first. The pan won’t be supporting the filter and it may start sucking air if it becomes dislodged.

    Look at shift solenoids if you have shifting problems.

    Still its a special tool, not everyone has it or are computer experts, and its 90+ postage on Ebay, the one for 75 only clears ABS light.
