Should you bump shift an A4 4L60E?

on a stock 4l60e? have you ever tried it at all? what was the result? me personally the first time i tried to hold it to shift and click it up a gear it just keep going and banged the rev limiter. i started doing some research and lots of people have this problem. i think its because inevidently the computer controls the shifts not your right hand so you are at its mercy for good or bad. now if i go from say a 40 to 50 punch i will manually pull it into second gear, when i stand on it i click it to drive way before its time to shift and the computer will shift at the preset shift point. therefor avoiding a hard downshift into second from fourth possibly causing a trans breakage. if you hold it till its time to shift then watch out. i have also heard that actually starting with the gear selector in first from a stop engages some other part in the trans and makes the first gear a bit stronger then if starting in D. i dunno what it was bc im not an expert but maybe one can chime in.

so what im saying is by manually moving the lever, if you want to shift at 6000 rpms and you click it at 6000 rpms it wont shift, you will bang the limiter.
which kinda sucks...my 700r4 would shift when you hit it, that with a ratchet shifter made the car very fun and controllable, especially when trying to hold gears on backroad corners and power out of them

It's pointless to try and manually shift an automatic valve body trans. If you are unhappy with the shiftpoints etc, tune it. You're not going to gain anything by bumping the shifter around as it is
Rather, if you like the manual shifting, you have a few options. Get a manual valve body A3/A4, or get an M6

You really need to drive a full manual VB to understand what it means.
The transgo kit lets you manually upshift it only after the trans has been commanded to upshift.
A better example would be the chart below. With your kit you cannot manually shift into 3rd at WOT below 76 mph.
With a full manual VB you could shift into third, well you could start out in third if you wanted.

my point was that it gives you more control over whats happenning with the shifting but i did not mean that it was the same as an older non-computer controlled trans. 9000 got into the technical aspects that i didn't really deem necessary for the OP. the HD-2 seems like it will allow him to do what he wants to do with the shifting although it is not technically a fully manual valve body.
