#771 of 1368 Manually shifting the automatic; Harsh, jarring, upshift 2nd-3rd
Jan 25, 2007 (10:14 am)
This is the first post from me on the M board. I have a 2006 G35 Coupe. I'm posting because I have a problem with the transmission in my Coupe that may pop up in the M45.
When shifting manually, sometimes the shift from 2nd to 3rd is very harsh. It actually slams into 3 so hard I wonder if the rear end is going to show up in my rearview mirror.
Dealer tried a new valve body but it didn't fix the problem; they are busy now putting a new trany in the car. New I say because apparently there are no rebuilts available for my 2006 Coupe. That's a good thing, I would not have been happy with remanufactured.
The kick here is that the Dealer had two cars in the shop with exactly the same symptoms; you guessed it, the other car was an M45. Apparently the two share transmission components. The two tranys are not identical but close.
I don't have any info on the M35 but since it uses the same engine as the G35 the tranys maybe identical.
The Dealer has questioned Infiniti several times but has been told there is no "problem" with these gearboxes. I got the impression the Service guy was skeptical. He is still amazed they would have two cars in at the same time with identical problems. (Yup, the M is upshifting hard between 2nd and 3rd too.)
Well, back to my G35 Coupe board; just thought you might want to know.

They're replacing mine on Monday in a 2006 M35x with about 15K miles on it. The loaner (a G35)had a perceptable difference on the 2-3 shift vs the others, so I think it is a generic problem. Hopefully, the new one is better!

I'm not sure, but the heating/cooling MAY be from a peltier diode type component, and not directly from the hvac system. Anyone know for sure?
#774 of 1368 Anyone bought the M's service manual?

Has anyone bought the M's service manual? Retail is about $220 and a cursory search didn't find it for less. While I normally don't do much work on a car, it is nice to understand what it entails and to have a decent wiring diagram to decide if a tweak is possible or desirable.

Long overdue follow up on this post that seemed to fall into never never land. I took my '06 M35 Sport in for the 15K service last Friday. When I finally got a chance to look at the receipt last weekend detailing the work that was done, what did I see? I saw that the recall for the ICC was done during this visit. Interesting that I never received any feedback from Infiniti after calling to find out what the deal was back in July '06. I just assumed the recall had been cancelled indefinitely. I guess it wasn't a life threatening thing. Although I would think the correct functionality of the cruise control would be a major safety concern which should have been addressed asap.

New tranny is hooked up and I'm back in the seat again. By the way, there is no doubt, the sedan seat is wider than the Coupe. I was comfortable in the sedan but the second I got into the Coupe I felt the pressure of the seat control panel on my right thigh.
Car shifts fine although I thought I picked up a bit of an affirmative bump 2nd to 3rd this morning. We'll see over the next week or two if it's really gone; maybe the new tranny will develop the same problem. Hope not. If anyone can bring out the problems it may be me, (Infiniti may put me on a "Do not sell to" list.) Do Dealers share those lists?
Funny; when I picked up my G35 Coupe the guy with the M45 that had the same problem, (and also just got a new transmission), was standing at the counter going over his invoice for the tranny, ($4,000). We were both covered under warranty of course. He apparently did not know a Coupe was in with the same problem and seemed concerned that we might have the same transmission. Service tech stated they were not identical. I'll bet the differences are not significant; mounting brackets, etc.
The tranny and test results were headed back to Infiniti for analysis by the engineering folks who were interested in trying to sort out the problem Dealer said. I bet so at $4 K a pop.

I don't believe the M uses peltier diode components for heating/cooling the seats. While useful in small footprint applications (such as computer CPU cooling, drink holder cooling, etc), the last time I checked peltier diodes were notoriously inefficient, dissipating a significant amount of heat for only a little cooling, and may not be well-suited when trying to cool the larger surface of a car's bucket seat.
Also, anecdotally, the fact that the seat's cooling/heating is almost perfectly timed to the status of the car's climate system certainly indicates that they are simply capturing heated/cooled air from the climate control system and forcing it through the ventilated seat via a blower. That would also certainly justify the formal name for the system being "Climate Controlled Seats".
Interestingly, if you get the M package with the deluxe rear seats, they are heated using traditional, dedicated electrical heaters. Too bad they didn't elect to combine the best of both worlds and use quick-warming electric seat heaters for winter plus the a/c cooled air for summer.
The "climate controlled seats" do take longer to warm up than the "old fashioned" electric kind, but having access to the ventilated cooled seats in the warm months makes it worthwhile, IMHO.

Amen. Perfectly explained and I agree with your final comment. The concept of using "climate controlled" air really makes sense. Unfortunately, the engineers didn't consider that most people use the heater function to stay warm until the climate control kicks in. Also, many people have begun to use the seat warmers as therapeutic heat rather than a function to keep warm. My girlfriend keeps the seats in her BMW on the high heat setting even during the summer.
Though others on this forum have commented otherwise, I have yet to drive a car with seats that cool as nicely as the M. Other manufacturers merely run fans to reduce sweat on your back... giving the illusion of cooling. The cool air from the climate control system on the M is terrific.
#779 of 1368 spotting on the grille?

Anyone know of an effective and safe polish for the grille of the M? I have a number of spots related to salt or magnesium chloride or whatever they use in Colorado.

You really need to experience the Mercedes ventilated seats this Spring/Summer. The M's seats are utter rubbish in comparison, IMO, of course. The beauty of the Mercedes seats is that they are engineered as they should be. They don't force air through the seat, they draw it out. Much more effective at eliminating and preventing sweat and cooling you off.
I've tried the M's seats and didn't care for them at all. It seemed to take forever for any cooling to begin and when it did, it seemed to only be on the seat bottom.
