    When I say small, I'm talking 2 degrees at a time. I would suggest that you set all of your governor changes back to stock, before you start making changes to the TVA. Making governor changes can have very bad effects on the transmission.

    I don't know that it doesn't work. I haven't tried it. You would be better off making small changes to the TVA position.

    It seems unlikely, because the axis' in UDC Pro matches what is mapped in all the other 48re tuning tools.

    Does your transmission have a shift kit, or modified valve body in it? Has the line pressure been mechanically adjusted higher? Some pids are calculated values, like the engine oil pressure one on some years. The oil pressure sensor is actually a switch, and the value that is listed is calculated on what it should be based on rpm. Like I said though I do not know on the transmission pressure one on an 05. And seriously, I would start back with stock tables and make small changes one at a time. Just be prepared that not everything you want the transmission to do, will it actually be able to do.

    I would not assume. Measure the actual governor pressure (and line pressure) and verify. I've seen documentation (not MADS), that lists the pid both ways. Dodge lists the sensor as a governor pressure transducer, but we don't know what the pid actually measures. It could even be a calculated value. I really don't know. What I assume and what I think really doesn't matter. Only what I know.

    Even without trying it, I suspect the behavior you describe is correct. What do you have in the unlock and down shift tables? I would suggest you start with the stock maps, and make small changes one at a time. When you detect something that is undesirable figure out why that is happening. Are you sure the pid in the touch that is listed as transmission pressure is governor pressure? Paul

    With all the problems you are having that I cannot duplicate, I would suggest using a set of gauges and measuring the pressures directly. Probably the most commonly failed item in a 48re transmission is the pressure transducer. I stopped using the dodge one years ago.

    Yes, I know how it works, but my question was more what are you reading for line pressure, and governor pressure? Do you have the gauges hooked to the correct ports? Paul

    One other thought, you're not confusing governor pressure with line pressure are you? Paul

    The other tuning platforms have the same parameters listed in the tables. I cannot verify the governor pressures from any of the tools because of the mods done to the valve body on my truck overrides anything the ECM tries to do. I can verify that they all behave the same way on my truck.

    Also if I remember correctly it's little endian, so you will have to do the conversion. I can't remember for sure though if the 05 uses little endian. Paul

    When you look for the table in winols, also look to see if you can find a reference to that base address in the executable code.

    Have you actually used some of those parameters to see how useful they actually are? They may look actually pretty cool, but some of them don't do anything, and others work better if you leave them stock. I have seen a couple of parameters that I had thought might be useful (if they actually worked), but then I think have I actually ever really needed them? Paul

    Remember too, that just because the table exists doesn't mean that the OS actually calls it. One of the tuning tools likes to map tables even if they don't do anything, and they don't have that one listed. I much prefer only seeing tables that are actually called by the OS. UDC Pro is great about that. Paul
