335i, Clutch A appears to be failing

So I got the xHP flash tool and took a look at the transmission values below. It appears clutch A is going.

What are my options at this and how much is it gonna cost? It;s a 2014 with 92k miles.

Thanks,
Aaron

*EDIT*

I should mention also that I'm having hard downshifts when slowing down from 3-2...

Can't comment on whether or not that actually means its failing, but the best and pretty much your only (AFAIK) option for rebuild is https://www.puredrivetrainsolutions....-transmissions

In another thread, I found guidance saying it's fine as long as you're within +/- 350mbar. I'm with n55david unless you're actively having problems with shifts.

Edit: these are old, but the last time I checked my values at 60k miles I had -126 for A, -126 for B and +184 for C. You're fine.

K, thanks, I'll keep an eye on it and see if it starts to get worse. I forgot to mention though that I was starting to get hard downshifts from 3-2. I did a transmission flush when it started about two months ago and the system remained the same. I'm wondering if I should try a stage1 from xHP? Would that make it worse if or perhaps fix it?

Flush? or Pan and fluid? you arent supposed to flush.

XHP wont fix a mechanical problem, but it can improve shifting.

Stage 1 should be identical to the stock calibration minus the torque limits.

Did you fill the gearbox with it completely level? The gearbox isn't level when the car is. Tilting slightly backwards

Mine shifted horrible after service, on a hoist. But after i figured out the gearbox wasn't level I could get 0.7L more in after adjustment. Now it shifts like butter

You have to check right under the fill plug with a spirit level to ensure it is level. Not on oil sump since it is tilted
