performance shift was actually removed from most cars in 01, but the functionality stayed in the pcmif you put a pin in the connector and grounded it.

This makes sense but in 2003 when the 4T65eHD was redesigned, I believe that the feature may have been completely removed. Regardless if we want a performance shifts we can do it very easily by adjusting the software. My trans is programmed to shift at 5550 RPM at WOT.

The perf shift tables are still in the bin file on a 01-03... it has nothing to do with the actual transmission anyway, its just a shift pressure and shift point modifier.

Yes you are certainly correct about this but on my 03 PCM which I believe doesn't have switchable performance shift, the normal and performance shift table settings are identical. I believe this to be GM's answer to saving a 25 cent switch.

That and maybe GM didnt like the idea of it shifting the trans harder.. who knows. some of the base shift logic changed in 01+ years too.

What AWG wire is used on the PCM? I am running a few new wires and want to get the correct gauge wires.

I am really sorry to have to do this to anyone but , Caution to anyone thinking of dealling with Dan Mcllmoyle "FIEROFLYER"
I sent him $550 dollars along with my 3800 wiring harness and computer over 4 months ago. He told me it would be a couple weeks to do the new harness up and reprogram the computer.
He has moved will not answer emails and the phone number he gave me is disconneted. This amounts ot fraud over $1000 dollars in Canada
