How to Cancel Immediate Upshifts when Switching Into S+ Mode from M @ High RPM
Lets say I'm driving my car in M mode in high RPM range on the highway. E.g. 2nd gear 60mph. I want to put it into S+ mode to launch and not miss shifts. However, as soon as I put it into S+ mode, the car starts upshifting through the gears. Goes from 2 to 3, 4, 5, 6.
It's very bad when I go from M to S+ and step on the gas. The transmission quickly puts the car into higher gears and out of the power band. Of course, I can cancel this by just downshifting, but I dont want to have to switch to S+ and quickly downshift to cancel upshifts which should not happen in the first place.
Is there a way for me to keep the D1, D2, D3, etc "lowest gear" setting even when in M? This would actually be the solution since the TCU would recognize that it's not supposed to upshift until redline anyways, as long as I have a low enough D# setting. Hope I presented this situation clear enough.
Car has EC v6.

Of course not, which is why I want to put it into S+ mode. But then if I'm already at high revs in M and switch to S+ it starts grabbing higher gears

Why would you do any of that, it makes no sense. Just use the paddle.
Anyway, those are the precise conditions where you shouldn't be changing shift programs. In fact, they say in the owners manual not to change programs while moving. If anything, you should switch in a low rpm and low load situation.

Have you tried holding the downshift paddle for as long as required?
My car will hold a gear in s+ for a while if I engage a downshift but this lasts for say 10 seconds I find blipping the throttle helps

Yes, holding the downshift paddle automatically puts me into the lowest possible gear, but it doesnt really solve the issue of the TCU not holding the gear upon first entry into a new mode, since itll clear any "held gears". This is a problem when driving in high RPM in M mode!

news to me too. I don't change at high revs but I might be cruising low rpm but 40 mph and change to s+ mode. Doesn't seem to ever have an issue with it. If we arnt supposed to do that I will def stop

If you over rev in M I expect the rev limiter to tell you pretty smartly.

I think the owners manual says to shift between any auto mode to manual while stopped. I interpreted that to mean its ok to shift between the auto modes while moving. I.e. crossing over between auto and manual while moving is bad, but changing between auto to a different auto while moving is ok.
From the manual:
"Only change from automatic drive program C,
S or S+ to manual drive program M when the
vehicle is stationary".
The real answer to your question is in your manual around page 151.
Take some time to read everything about your transmission and you will then understand how it works and how you should use it.

The gearbox doesn't just select a new gear. There are all kinds of changes in things like shift points vs rpm and load, the pressure sent through the VB increases/decreases depending on mode, etc. Ever downshift too many gears on a manual trans and you bang the redline? That could easily happen too if you shift for instance from C to another mode in a high speed low rpm condition for example. Although you're unlikely to blow up your trans (unless doing something supremely stupid like the OP switching programs at high rpm or load), it's just not a good idea.

BlkRokt's explanation should suffice for sure but dude, why do you think you know better - or assume you know better - than the guys who built the damn thing?
Take the time to learn if you do not understand how this thing works. If you don't want to do that or listen to the advice you are seeking on this site I can only suggest just do what you want but a) get an extended warranty before you do and b) make sure there will be no codes revealing what you did the micro second before your tranny goes BOOM! so when you ask the insurer to pay to fix it which I suspect will be around $10K there will be no evidence you did something contrary to the manufacturers instructions that cause it to implode.

Actually re reading my post I was a bit grumpy this morning.
Actually the manual description on controlling shifts in S, S+ and M is pretty self explanatory. You can manage it without using M.
If you do not have a manual you can download a PDF version. I have the 2013 version if that helps. I would send if you PM me.

It says we shouldn't go from any of the auto modes (C, S, S+) into M unless stationary.
It does NOT address shifting between auto modes (C to S, S+ to C, etc) while moving.

Like much of the manual, this seems as clear as mud. If what you gave us was actually the entire text, then it is pretty limited:
It says we shouldn't go from any of the auto modes (C, S, S+) into M unless stationary.
It does NOT address shifting between auto modes (C to S, S+ to C, etc) while moving.
It does NOT address shifting from auto modes into M while moving.

I shift up and down in any auto mode mode using the paddles or the shifter and on the rare occasions where I want to move from actor another AUTO mode it seems to it pretty seamlessly. I NEVER go in or out of any auto mode to M.
Maybe tomorrow I might read again.
