Rev Matching (5at)
#16
I beg to differ... Don't ask me how I know. There is something scary about seeing the tach creep past 8k when the factory rev limiter is at around 7600. I reacted properly though and no harm was done. The engine can safely rev to 8k, but if you start messing with downshifting by "double clicking" the left paddle at too high an rpm for a double downshift, you had better know what revs you'll end up at after the tranny drops 2 gears down.
I'm not sure if the safety was designed with downshifting more than one gear at a time in mind. So I thought I'd mention it.

Also the tranny will not downshift until you are at the proper speed for the gear.
The tranny can do what ever you want it to do. If it was bad for the tranny it would not do it. AKA Downshifting to first from 5th at 70 mph it wont do it.
Down shifting 2 gears, sure that's fine.
All the shifter does in the cabin is tell the TCU to downshift two gears. Your not forcing the transmission to do anything.
Again if you tell the transmission to do something bad it will not do it.

WOW. screensaver, malice, and steadfast how are you all so ignorant? One person that ignorant, fair enough. But there are 3 of you. That's what makes it so sad. Maybe its my fault for not describing it clearly enough. Or maybe rev matching wasn't the word I was looking for. Is there even a word short for "tapping gas pedal during a downshift before the gears engage, in order to prevent the car from lurching but instead smoothly shifts without lurching". If that's not 5at downshifting, please inform me what is it. Possibly I have been the ignorant one here instead...

Wait, aren't you the OP? Sorry, we forgot about you.
To answer your question: No. I personally do not tap the throttle in auto during a downshift. The auto tranny (due to its design nature) never completely disengages from the motor during shifts, so it's somewhat pointless. If you feel it making a difference, more power to ya. I was merely pointing out that if you double click the left paddle or click the shifter back twice quickly, the tranny will skip a gear downshifting. The ecu will need to blip the throttle harder, and you'll end up with a more pronounced rev match. Does the ecu do a perfect job every time? In my opinion, no.
Now can we get back to our pointless discussion of whatever it was?

I'm not sure about you but my fairly outdated tranny (compared to yours at least) rev matches just fine. There will be a hiccup every now and then and it doesn't match it too well but never to the point to where it would buck, and even then that's a rare occasion. Maybe you should check your tranny for issues...
The last time I heard people talking about rev matching a 5at was for the 03-04 models...but even then, I'm assuming it isn't that great for your transmission since you're forcing it to rev while it's engaging slip in the torque converter.

Lol thanks for a more reasonable helpful response, I do not think it is a problem at all, it feels like it should though and my previous borrowed 330ci did it too... someone told me tonight that it might also be called downshift engine braking or something, but I'm just gonna drop the subject since no one has any clue what I'm talking about. Now I know never to ask hard questions like this here...maybe nico club...?

^ You titled the post, Rev Matching. you OP continuously says Rev matching.
You don't explain your issue, and there is not such thing as rev matching in 05+ AT's
So you take your foot off the gas and blip the throttle when its downshifting?
I can be full on the Gas or of the gas it downshifts smoothly for me.
So you mean engine braking, is that why you think its rough? its changing to a different gear, with no load it will just engine brake.
If you get on the gas a little bit it will be smooth as butter reason being no engine braking.

LOL what the fvck are you ranting about? who said they almost had you? isnt that a bit homo?
BY THE WAY, theres a thread about double clutching if you ACTUALLY think thats how you should shift... https://g35driver.com/forums/g-spot/...-drive-mt.html please read this ASAP to learn how to shift son
