Hard shifting after PHP install

[Power Hungry]

Are you running the standard files or the "Hybrid Shift" files?

In most cases, swapping to the Hybrid Shift versions really helps the shifting. I'd give a couple of those a try and let me know. I've run these and the only complaint I usually get is that the shift points seem a little odd because of the way the converter is handled, and people just aren't used to it. The strategy is actually built off the 1999-2001 shift strategies which had a different feel, so people can get a little confused when it shifts differently.

As an aside, you may also want to throw one or two of the Modified Valve Body tunes on for testing as well. They have all the line and shift pressure modifications removed and might help alleviate the firm shifting as well.

Let me know how it works out and we can investigate further if needed.

Have a great weekend!
