I haven't taken this apart yet, and before I do wanted to ask - if I were to remove the Y3/8s1 sensor from the conductor plate and put replacement in, do I still have to program the conductor plate (ETC)?
Vehicle: 2011 GL350 (X164) with 722.9plus transmission
Code: 0705 - Component Y3/8s1 (Selection range sensor (VGS)) is defective
Symptoms: while driving, transmission will get kicked out of gear into neutral and no gears can be selected at that time (neither lever or shifters). Once I stop and shut off ignition and start car again I
am able to shift into D again (or select gears with shifters)
From going through the forum, couldn't find information about removing this one component. I know replacing whole conductor plate = reprogramming, but wonder about this one sensor?
This range selector is very easy to be replaced, no re-programming will be needed, but it may be necessary to re-learn the P/R/N/D positions with a diag system after everything will be installed back.
Curious if you went ahead and replaced the selection range sensor or just got a new conductor plate altogether. I have the same code along with a very infrequent 0606 "Fully integrated TCM is defective". I've only had the blip into N a handful of times & it would only last 2-3 seconds. No other drivability issues.
If you covered the CEL (or during the day or 2 it stays cleared), it would be impossible to know there were any issues. All live data suggests everything is working fine, when it clearly is not with a reoccurring CEL. I hope you got yours resolved.
you mean the solenoids? I haven't done this work yet, cause rarely drive this vehicle but getting ready for it. Yes please let me know sizes, I see there are 2 per solenoid one is slightly bigger than the other one. Anything special about these, or just regular O-Ring?
haven't done it yet, but probably within the next 30 day will be finally doing it - rarely drive this vehicle and short distance only, so wasn't a critical thing for me yet
Max the 2 Orings listed are for the shift spools. 1 smaller and 1 larger per spool. I never found a mercedes listing .. they want you to buy the new shift spool(solenoid) I think ??
The first time I ordered them the gentleman that started the Oring company worked on many mercedes trannys . We both got a good laugh when I told him what I was working on.
thanks for this - ordering this right now and once I have all parts in, will be getting this done. Will drain all fluid I can (tranny pan and TC), then drop valve body and clean up conductor plate - the sensor I have and is causing me issues, I'm assuming it's just dirty and magnets get faulty readings from time to time - obviously don't know the full picture until I take it apart. At this point it seems like 50/50 on my end if I buy sensor from ebay or put mine back in.
I hope you have wonderful 2026 - thanks for the O-rings, really appreciate, ordering from same spot.
Yes Orings have to be the right material to deal with tranny oil and heat.

Hey Trigital,
I have soldering and electronics experience, just wonder if this is also part of TRP theft related part and will cause or not cause issues. If you say easy to replaced, and no re-programming needed, meaning it won't cause 'theft' related issues?
Update: finally got to do it, pulled the conductor plate, nothing unusual. O-rings on solenoids were in great shape, but replaced them. I found a lot of gunk built up on the gear selector rod - so cleaned it up. I also removed the conductor plate from the valve body and cleaned up sensor from under, but nothing unusual to report there.
Put it back together but had the same code coming up few days after, actually twice so far.
I'm going to try the TCM reset, and maybe shifting reprogramming. Unfortunately for my DAS I put myself in a bad spot. Not knowing how this works, I started the programming of new conductor plate. Meaning, I saved my data to the software, but now when I connect to my car it is asking me to continue with the replacement procedure. So I'm a bit stuck what to do there (don't want to damage my conductor plate just yet).
Your Fault Code is about a "Defective" selector range. There is no sense in "programming" or "resetting" anything when you have a defective part.
You can change the sensor with another one from another TCU or you better change the TCU as now after playing "outside" in the open air with a very old plate, the oxidation will be aggressive.
