I have a 01 C2 tip. Shifting from 1st to 2nd always happens around 6200 RPM either in M or A. All other gears always shift around 7000 RPM. 3rd to 4th shifts at 7200 RPM.

The problem with shifting from 1st at 6200 is you drop down to 4100 RPM where there is a little hesitation before the RPM's go up quickly. Is there any way to get the transmission to shift at 7K in 1st gear. I've tried disconnectiong the battery but this has no effect. Thanks.

 

Your shiftpoints are at 7k?
I assume this is only under WOT (wide open throttle... flooring it)

 

Yes, aren't all 996's suppose to be at 7K

I had it reprogrammed with an upsolute chip about 4 years ago. I think that's why it shifts at 7200 RPM from 3rd to 4th. My battery has died a few times and I've disconnected the "-" on the battery when I had the EVO intake (no extra hp but sounds cool) Fabspeed Maxflow exhaust and headers put on ( again no new hp, but sounds great) and IPD plenum but in (I'm doing a dyno to determine any extra HP). I assume any programming stays even if the battery is disconnected.

 

If I'm not mistaken, the manual cars would probably have the same rev drop during shifting? I'm a little confused why you would be skirting with disater by trying to keep the Tip box near redline consistently? The fraction of a second gain and the little hp/torgue gain seems hardly worth either blowing up the box or frying the torque converter IMHO. Anyone who buys your car will definitely see the high number of type 1 overrevs it has.

My 02 tip shifted 1-2 at redline (7k), but the 02 tips were an updated version (turbo) of tip trans with a lot more logic built into it. Could just be the nature of the early tip.

Porsche set the WOT redline shift points that way on purpose, I don't think it will damage your car.
