Upshifting after a spin is not possible

[Felix Nudrec]

Hej all,
after an spin in the Porsche 992 Cup I wasn't abel to shift up again.
If I spin, I switch back to neutral and when I try to continue I get stuck in first gear, I hear the shift protection the whole time. I can only solve the problem again if I drive slower than 50 km/h and go back to neutral. If I just brake, stop and don't go back to neutral, this problem won't be solved. Here I get stuck in first gear.

The problem persists with toggling the following driving aids on and off:
Auto blip
car lift
Autoshift
traction control

If there are important points are missing feal free to pointing out.

Can't say for certain, but once you recover the car, are you applying throttle? The Shift protection requires some throttle before it will allow an upshift.
@Craigbowie That almost sounds like your controller has a dirty or worn switch/connector. It produces a short spike that only completes half of a downshift procedure.

Half a downshift? How does that work? Does an extremely short press of a shift button do half a shift, ever? If you've never heard of such a thing, why are you proposing it now? (yeah, I'm pre-empting your answer, I'm sure you were just making an ASSumption...)

@Craigbowie Either you've uncovered a bug or you have some intermittent controller issue. It's really not related to this (shift protection) at all, and you should make your own thread (or post in a relevant one) to avoid confusion in this one.

Can you just step that out a bit more, assuming you can reproduce this consistently?

You spin, then:
- press Neutral
- change to 1st
- and now it won't change up any more?

Then you can solve the problem if you drive slower than 50kph (were you still going fast before?), and go back to neutral (so you can then shift up through 1st gear fine?)

If you come to a complete stop in 1st gear, you can't change out of 1st gear? I presume you mean without going back to Neutral as above?


Explaining a bit more will help to reproduce it (so if there's a bug it can be fixed) or potentially you or we work out what's going on, and what you might not quite be doing right to make the shift protection happy...

Id agree if i was trying to change gear, im using a Jinx Shifter and when this happens im not actually trying to change gear. Only happens in top gear (6th) when your going on a straight. Im not touching any buttons or the shifter.

I also think this is a different issue than OP's and so it should have its own thread. There's no benefit in mixing issues in one thread. And most probably more related to hardware faults. It sounds like a microswitch failing. It would do exactly what you're describing.

In two chases i was spinning and while I was going sideways I hit Neutral. Then I was straight an go in gear 1 while still rolling.
Then I wasn't able to upshift anymore, with any amount of throttle. 0%, 25% 50%, 75% and 100% didn't work.

Then you can solve the problem if you drive slower than 50kph (were you still going fast before?), and go back to neutral (so you can then shift up through 1st gear fine?)

There are two ways I can reproduce to solve the problem.
1. Stop completely an go back to Neutral and start again.
2. Go slower than 50 kph an hit neutral and step on throttel again and go on.
The 50 kph came from my trys to make the car going after the problem appeared already.

If you come to a complete stop in 1st gear, you can't change out of 1st gear? I presume you mean without going back to Neutral as above?

Yes thats right. If you stop without Neutral you can't shift up so 2 gear.

Explaining a bit more will help to reproduce it (so if there's a bug it can be fixed) or potentially you or we work out what's going on, and what you might not quite be doing right to make the shift protection happy...

We found something interesting in the severreplay, I was fully on throttle but on the sever I was maxed out at about 50% or below. So maybe there is something preventing the car to go full throttle.

I hope this helps, if there are even more questions feel free to ask.

Thanks!

Here's what I just reproduced pretty quickly:

- Drive into 3rd gear
- Change to Neutral (directly)
- Car won't upshift into 1st until about 69kph (shift protection, but much lower than normal) (<giggity>)
- Accelerate to above 79kph, car won't shift out of 1st, no matter how much throttle, until the speed goes back down to 79kph. Stopping the car and going again doesn't help, if you wait until >79kph before trying to shift. It just won't go.
- Hitting neutral again does reset it, and it works fine again.

Interestingly, on quick tests, this doesn't happen when changing to Neutral from 2nd or 4th (or 5th) gears. You still can't get into 1st until you're doing the magic 69kph (<giggity>), but then it shifts freely.

So there seems to be 2 factors I'm seeing so far:
- going into Neutral from higher gears forces speed down to 69 (<giggity>) before accepting 1st gear
- going into Neutral from 3rd will stop the car getting out of 1st unless the speed is below 79kph.

Wild guess: various malfunction and leftover parameters from running the higher gears; logic probably designed around sequential shifts, not breaking back into Neutral and starting again.
