Infiniti G35 - How to Fix DS Mode Transmission Problem
HTML-код
- Опубликовано: 13 сен 2024
- If you have a 2nd Generation Infiniti G35/G37 (2007-2014) and have experienced problems with your DS transmission mode, this video may help. I have a 2007 G35x with 88k mi. I drive almost exclusively in DS (sport stick or tiptronic trans mode). Recently, I noticed that the DS Mode in my car would suddenly stopped working and the car reverted to Automatic Trans mode (D instead of DS/1-5 Mode as seen on your dash). In my case, shutting down the car and restarting it resolved the issue at first. But, not longer thereafter, the issue became progressively worse to the point where DS Mode no longer worked.
After reading several forums, the common fix appears to be replacing the Transmission Shifter Assembly, Infiniti Part # 34901-JK60C. Others have mentioned needing to replace a related solinoid as well. I read in one forum where one person was able to remove excess white lithium grease present below the shifter and that solved his problem after two tries. This comment gave me the motivation to investigate further and here's what I found:
There are three contactor switches on the shifter assembly. Two of the contactor switches control the +/- shifting action. In my case, these appeared to be fine and are easily visable on the drivers side of the shifter as blue contactor switches that are actuated by stainless clips when the shifter is toggled forward or back. The contactor switch that is the suspect is the DS Mode contactor switch. You will hear this switch as you toggle the shifter from side to side. Finding the switch is a bit tougher. The best way to see it is to remove the center console's cupholder assembly. Once removed, duck your head down behind the shifter assembly while using a flashlight and move the shifter from side to side (simulating going from D to DS modes). If you look closely enough, you will see the contactor switch. In my case, it appeared to have a fair amount of white lithium grease smeared around the switch. Using a can of electrical contact anti-corrosive spray with an extension straw, I sprayed the DS Mode contactor switch and this appears to have solved the problem. I also sprayed the lubricant within the associated white connector that was mentioned in the video as an extra measure.
The video does a fairly decent job of explaining the process and here are a few extra notes that may help you out:
1. Be sure to be on flat ground with your emergency brake fully depressed (your car will not be in the Park position during this process).
2. This link will help with the center console removal: www.nicoclub.co...
Note, for your process, you will not need to disconnect the battery. Also, I suggest placing the shifter in N for easier removal of the the boot.
3. To remove the shifter knob, pull the boot down to expose the shifter lock-clip, spread the lock-clip ears on the front side of the shifter with your fingers while pushing the lock-clip forward and then pull it toward the rear of the car to remove (observe the orientation of the clip for later reinsertion).
4. To remove the boot assemby, grab from the rear of the boot and lift (be sure the shifter is in the N position). Also disconnect the two electrical connectors.
5. Remove the center console's cupholder assembly by sliding it forward about one inch (as far as it will go) and then yank upward on the backend. Also disconnect the three electrical connectors.
6. Remove plastic cross member that seperates the boot and cupholder pieces using a phillips screwdriver (two screws).
7. Remember to push the transmission emergency lock release (the white button located on the forward/driver side of the shifter) to allow the shifter to move freely while performing your operation.
8. Before starting, buy a can of contacts cleaner/lubricant. There are multiple products out there that range in price. Here are a few worth mentioning:
- www.homedepot.c... (about $3)
- www.homedepot.c... (about $8)
- www.amazon.com/... (about $12)
- The product I used was purchased at Radio Shack in 2015 (same as Deoxit & made by Craig for both) for $2/can. Unfortunately, it appears to be discontinued.
My recommendation is to get the CRC 2-26 at $3 from Home Depot. It gets excellent reviews on Amazon and likely is as good as Deoxit. Some also recommend using the CRC QD Cleaner ($8) first and then apply the lubricant. I only used the lubricant and it immediately did the trick. While at it, you may want to squirt the spray on the contactor switches that control the +/- shifting action as well.
If you have the same result as me, your DS Mode will work as good as new and hopefully for at least another 80k mi or so until you need to clean the contactor switch again.
This video helped me solve a very similar issue with a 2009 G37, sport mode worked but when I tried to use manually shifting the car would revert back to regular mode and I wouldn't be able to get sport mode back until turning the car off and on again. I sprayed some contact cleaner on the up and down contacts and it seemed to have fixed my issue.
Thank you very much for the video.
hi Joe I have the same prob where my Tranny won't switch from D to 1, ever again. Did you have to take apart all the consoles and stuff ? Thanks
@@harryvuong638 same
This really worked for me!!! A buddy of mine sent his out for the same problem and they charged him $1200 to replace solenoids.. or so they said. Thanks SO much man!!
I tried this so I have to soak it or what?? And the light on the shifter next to the plus and minus is on with light for the position of the shifter. Im wondering if I have to soak it or dry it or some thing
Did you have problems with up and down shift also?
just did this on my g37 and it works perfectly fine now thanks so much 🙏🏻
Thanks for this video sir, I'll give this a try sometime this week and phone in the results~!
Edit:
So update this didn't end up fixing my issue, there was a excessive amount of silicone around the switches but transmission is still reverting.
Back to the drawing board for me, good luck to everyone else an easy $8 attempt so it's at least worth the try IMO.
I have silicone around mine too 🙃
@@cmpunk6481 Ooooh my.
@@BigHeadClan did you end up fixing the problem?
@@cmpunk6481 Nah it didn't work, doing a bit more searching the early 08-2010 models usually had to have the console shifter assembly replaced.
It's intermittent though so not the end of the world, once I track down a good donnar car I'll swap it over.
@@BigHeadClan I tried without the spray and was getting there, every time I moved it into DS it was working more frequently, so I'm going to try the spray next
Don’t know why I never saw this earlier but good video great explanation, will try this on my G
thanx for the info....i have a Suzuki 09 XL7 and the manual shift mode just kinda decided to not enable when put into MSM ..or sport shift whateveritscalledonothercars ....
i hope this will help...i don't want to have to get taken to the cleaners over a simple fix....and i've been looking all over the internet without any results for about 2 months ...till i guess i googled the right string of keywords ...and found THIS!!! :)
i'll get back as soon as i figure out how to get to that switch after i get the contact cleaner... ty again...wish me luck ...TY!!!
This worked for me thanks man.
What did you use
Thanks for making this vid bruh it helped out a lot
Nice description... Do you have detail instructions or links on removing the center console. From your description it appears that you don't need a panel/trip popper tool, and that a good tug on the boot will suffice.
first time spraying and it finnaly goes in to the mode then goes out the MM mode.
Anyone know why when I come out of DS and into Drive mode I can’t go back to DS without turning my car off for 15 seconds? Then it works again
UPDATE: 4 years after performing this procedure and the car still shifts like it was new. One thing worth mentioning is that I used a Radio Shack contact cleaner that is apparently made by and is the same as Deoxit D5. The Deoxit D5 isn't cheap but it "could" be the difference between those that have had success and those that may have tried a different solution. Apparently, the Deoxit D5 has some special sauce that distinguishes it from other solutions. Here's a well-done video on contact cleaners that may be worth the watch and you can make up your own mind as to what solution may work best for you: ruclips.net/video/ygrlO_VacsY/видео.html
Here's another good related read: hackaday.com/2017/02/17/contact-cleaners/
Does this work for the 05 g35x model? Mines throwing me a p1815 code.
@@adriangoodbear8304 I'm not familiar with the 05 G35x. However, a quick review of the P1815 code and the symptoms reported by others (downshifting w/o user input), it appears this is a different issue. Unfortunately, other than making sure your transmission fluid level is where it should be, I have no experience to point you in the right direction.
I did this method so far it's working ! I spray it a lot everywhere lol 😅 at first it wasn't working but after it dryed up , starting working! I'll keep you updated hopefully it's doesn't back thanks again
Just used this method to help fix my sport mode, and I think I noticed what the issue was, at least on my specific car. The DS contact would not go all the way back up. After some contact cleaner and running a small flathead above the metal contact, the contact now goes all the way back up. I have a video of my D to DS contact motion that I could post if anyone is interested
Hey how did you take apart your console? I was having trouble with that, can you post a video?

@@vinceventresca6719 thanks I appreciate it! Can you also post the contact motion?

this is it working properly
i have this problem with my g37 sedan 2009 , and i do all those steps but it still not work ?
thanks, fix my problem.
Thank you
Great video. Been searching forums and no one has come close. Question. My problem is that my trans will downshift without any action from me. Could this be those 2 other contactors you mentioned?
Doubtful but possible if some conductive substance/material is momentarily arcing the contacts. Also, if your shifter is not entering (and remaining in) DS Mode when you move the stick, I presume the condition you describe is possible. The procedure is easy and cheap enough to try, if nothing else, to rule it out as a solution.
@@caymanwest4929 thank you for the reply. What happens is I will shift into sport mode fine. Shift up into 2nd. Then boom! Car shifts down a gear. I figured it may be related to this.
@@granzlewi In that case, it's possible the set of contacts that control the shifting are compromised (see 1:10 into the video). That set of contacts (located on the driver's side of the shifter) is easier to see and may be worth the attempt to clean them using a contact cleaner. Good luck and keep us posted.
@@caymanwest4929 awesome. Thanks!
Lewi 100 did it fix ur issue?
Does DS actually do something than plain D mode??
Yes sport mode, ups the rpms, u hit powerband faster
Anyone have a similar problem with the up or down shift not working the first try? If I press and hold up or double tap up it will shift up. I do have a p1815 code, no check engine light but I found the code with a obd scanner. I wonder if this fix will work?
Update. I used this process on the contacts for up and down shifting. I only used contact cleaner and it worked. I also sprayed the drive sport contact while I had the boot assembly off. If you spray from the top with a precision straw on your contact cleaner you only need to remove the boot. I was skeptical but it worked. Thank you very much for producing the original video.
@@BPattBdid the p1815 code disappear after?
@sleep5651 i cleared the code and it was good for a while. I did have to repeat the process one more time a couple of years later. I still have the car. It's got 198,000 miles and runs strong.
@@BPattB thanks for the response man gonna try it out fingers crossed
Will be trying this on my g35 coupe
Update: two weeks later, just tried it. Not sure if I sprayed the right thing but we'll see if it worked
Did it work?
@@rodrigorodriguez7915 sprayed it twice, second time seemed to free up more debris cuz my shifter worked better but it stopped working intermittently again. I'ma spray it again tho
Mine has this problem and the shifter light stays on D no matter where the gear is.
What is ds mode
Is your problem still fixed? I tried this, but it did not work.
jkunz27 - Yep, still driving it daily and never had the problem reoccur. It's possible you do have a component failure, but, I would give it another try. Just be sure to use a straw adapter and try to saturate the contacts behind the shifter as shown in the video using a contactor cleaner. I suspect white grease has inhibited the contacts. If not, one of the components others have reported to replace could be the issue in your case. Good luck.
Thanks, I will try it again. It is so frustrating because the rev-matching downshifts are my favorite thing about this car, and I can't afford $1000.00 For a new shifter!
jkunz27 hi did you ever get it fixed?
000CLos I have not tried cleaning it again. It's worse than ever now. It used to only act up when I was shifting, but now it defaults to D even if I'm just driving in DS.
So something bad just happen to my 07g35xsedan .I was racing someone on highway and all of a sudden the dashboard stop showing that I was on drive.or sport mode or park etc.. wont show nothing to show what gear I'm in.smoke started coming out my exhaust and when I shut it off the 🔑 light is on and it wouldn't start.eventuay started but driving funky.when I accelerate it takes a bit to catch and I looked under the car and it looks like all the oil exploded underneath.did I just blow a head gasket? Check engine light is on.it made it home.but definitely leaked a bunch of oil...
What ended up did you throw a rod?
Would anyone be able to help me . I have an g35 06 . The problem is when I put it in M mode , soon I start drivin it would put it self back into D and no longer go back into M mode
Could this work with The Reverse Contact Switch. My G won’t Recognize Reverse it’s Revs but doesn’t move
Same problem I have
Would WD-40 work you think?
WD-40 is conductive but I don't think it would be a good choice as long-term cleaning agent. You could try a combination of carb cleaner and WD-40 if you have them lying around, but, the smell alone could be a deterrent. Others with more experience may have a different opinion.
the code come on 2005 Infiniti fx35
Hi there, when my shifter is in DS mode, it stays there for 1 minute before it shifts to D. Afterwards, my paddles don't work at all, and the upshifts are extremely jerky. Problem goes away when I turn off my car. I assume that these dirty connections could glitch up the TCM too?
I can't answer that. I think the procedure described here is easy enough to try. It may resolve your issue and if not, the effort should be less than an hour of your time. If you give it a shot, please report back so others can benefit from your experience.
@@caymanwest4929 thanks for getting back to me. Turns out it was a plugged in Bluetooth OBD2 scanner causing my TCM to glitch lol. Glad I didn't have to do anything else
Will this work for my 2005 g35 coupe?
I’m about to try it I’ll let you know lol
