    Default E38/T42 4l60E P0717 Code

    I have a E38 (LS3)/ T42 (4L60e) swap in a vette. Since its a 4L60 instead of a 4L65 I am getting a P0717 code, is there any way around this or will I have to change the trans to a 4L65?

    Have you turned the ISS off in the TCM tune? Post the TCM tune and look at D7026.

    I havent tried that yet. I do have that table in the tune. Unfortunately the car is about 2 hours away from me. I am just trying to get some ideas before driving that far again. If this cant be resolved they have to take the body back off in order to pull the trans. This is in a $100,000+ mint show car.

    Set all parameters related to the ISS to "Not Reported" or "No". Many running this setup - will work just fine once you sort the DTCs out.

    Got to love people who spend big dollars, but cut corners on the little things - like the transmission.

    Try it, Ive heard that in the TBSS guys have swapped 4L60Es in that dont have an ISS and dont even get a code...that said, cant hurt to try it. Not sure what other tables need to be changed, but Taz is correct, just kill all the ISS tables. Its not really needed IMO.

    Just changing 0717 to Not reported will not work, I didnt try every code related to it though. Its a 100% brand new 4l65E from GM with a 13 pin connector instead of a 15pin. They are not not LS experts and never ran into this before. Corners werent cut on any of there builds, most are pretty much unlimited budget builds.

    OK ... somewhat confused ... in your first post you stated it was a 4L60 ... now it seems it is a new from GM 4L65. If it is a new 4L65 (which are still in use in production 4.8 L trucks) - then it will have an ISS, and the transmission connector will use 17 out of the 20 available cavities. The stock T42 for this transmission would have the ISS functions active.

    In 2012 a budget of 100K is pretty much entry level for a full custom build. Two of the custom builds I tuned last year each had budgets over 3 times that much. Neither used a 4L65.

    I am not getting in a pissing contest with you if you tuned a more expensive car, the cars bill is well over $100,000 easily but its not place to put someone's exact bill out there. This is actually the first time they used 4l60's in there builds 99% of them are 6l80's or magnum 6 speed's neither have anything to do with this post.
    I was told originally it was a 4l60....today they called back and said according to there part number and paper work from GM its a 4L65 not a 4l60. The car throws a P0717 code which is active in the T42 controller that was used in the car. Im stuck 2 hours away and want atleast a game plan to try before driving that far.

    Can the T42 be full flashed from a 2008 to a 2006?

    That was not my intent ... nor was it my intent to offend you ... was merely offering a little 2012 reality check. I understand now that you are under some pressure with this one - making the timing of my comments poor.

    To answer your T42 question - Yes.
