Auto - Early Shifts?

[MarkGT]

My 99GT AODE seems to shift around 5300RPM under WOT. I got the Diablo Sport and it firmed up the shifts some but still shifts at 5300. If I shift manually into second, it hits rev limiter or cuts out about 5900. Any body experience this or have any suggestions?

Mine does this as well. I think it is fairly normal. I have noticed if the tires spin just a little at takeoff or downshift it will rev almost to the redline.

MarkGT:

The shift takes, say, 1 second to accomplish with the separator plate holes in stock condition. You can quicken up the shifts by making certain holes a little larger. If the shift can be made in, say, 1/2 second, then you can raise the shift points. This will allow you to take advantage of more rpm/power. Take a look at "Transmissions 101" in the Tech Articles section of TCCoA.com for "how to".

nyuk98gt,
I think if you do the J-mod and quicken the shifts, the shift points will become lower.
My car used to shift 1 to 2 at 5800-5900 rpms. After the J-mod the car shifts at 5600 rpms. Still a little late for me.

You're right: the process to shift has occurred in less time so the shift will complete at a lower rpm. Perhaps I should have had more caffeine to get the old brain cells revved up before I posted?

Thanks for setting things right.

Is it really usefull to have the car shift at this high RPM considering it doesnt pull past 5300-5400 RPM. Just woundering

the guy who programmed my chip said that he got best results with it shifting at 6300. i this possible? or is it hurting me i still run mid 13 but if it will help let me know.
