Shift Problem Solution ( w205 No More Jerky )


Anyone who has shift jerked into gear 1-2 or 2-3 can try this Diverter valve DV+ T9358. It take 20 minutes to install and very easy DIY job.

I tried it for 6 months and there is no more jerky, run like an CVT transmisson

GFB’s DV+ solution is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/ turbo flutter

It provides an faster boost recovery on gearshift and during throttle modulation

Improved boost holding ability

You can also buy it on ebay , make sure the model is T9358 and the real one.

So will this work on a 2015 C300? They don't have years just says C300 on their site? What year and model do you have?

What W205 has a 1.8L?

Additionally a BOV is turbo related, not transmission.

I'm confused on how shifting is affected by the boost of turbos and not your transmission. I've had this problem and many people say it needs an software update for the trans.

The video I post is the same ideal as C300 W204 and W205 Turbo Charge.

You follow his instruction and do the same way on W205.

I did it. It makes my car transmission work smoother

I call Bravo Sierra on the BOV doing anything, here we see the actual resolution of the shift issue "software update", a BOV will not change how a transmission shifts.

Search the forms here, there are numerous references to after-market atmospheric BOV's and other than adding the "pshhhhh" sound at vent, do not improve performance.

Believe or not believe is up to you. Even if you put some bad quality gasoline can cause an engine damage. Everything need to have and experience in life. I did it and it worked on my car and my friend car. That's it. I have the right to share my good opinion.

Did you give your car a try yet ?

Back to reality though, I took my W205 in to the dealer last week and they applied software update campaign 2019030013 for the powertrain. Since I got the car back, all upshifts and downshifts are now smooth as butter.

I'm just not sure if it's smoother now because of the software update or because the transmission "learning" was reset as a result of the update. I guess if it was the latter, the shifts will gradually get rougher again.

As an aside, I installed a turbo BOV on my last car (Fiat 500 Abarth) and understand the mechanics behind it. At best the BOV will allow the turbo to recover faster after spooling, but mostly it just vents any remaining turbo boost/pressure to the atmosphere instead of recycling it back into the combustion cycle as the manufacturer intended. There is just no logical way it could affect a component as far downstream as the transmission.

So I reply to your previous message "The video I post is the same ideal as C300 W204 and W205 Turbo Charge."
The 204 c300 was a v6 atmo.​​​​
