    4L60E Hard shifting

    Hi Guys,

    Having an issue with hard shifting when putting a car into D or when shifting from first into second.

    I have tried multiple trans maps, mostly stock ones and also a few tuned/changes although nothing seems to change the settings. The trans has recently been rebuilt as the last one burnt out. It seems to only have been an issue after the trans was rebuilt and was shifting fine before hand. Before that we had fitted a cam and done an SD tune and was shifting fine.
    Trans shop says its tuning, we think it can't be as it was shifting fine before. Now no changes we make will effect how it shifts, it always shifts too hard.

    I have read lots on the HPTuner forum about this being an issue when faulting the MAF although we have those drop downs disabled, as they were from the stock file.

    I have attached current map (the one that says tweak), stock map, the map it left with 6 months ago and with a log.

    Any ideas would be great
