Are You Happy With Your 7 Speed Tranny?
If you have elected to live with the 2nd to 1st gear "bump from behind", how do you feel about it.
If you let the MB Service department impliment the varius "cures" and upgrades to it to try to fix it, are you happy with the result?
I for one, am sorry I let them try to "fix" it. The upshift from 1st to 2nd is abrupt, and the downshift from 2nd to 1st at a stop sign is way too slow and LATE, so that if you try to stop at a stop sign & then stab the gas to pull away, the car slams into first.
HATE IT, HATE IT, HATE IT!!! Very unhappy with the monster (FrankenTrans?)they created after applying the cure. I don't know if I can live with it, thats how terrible it is. I hope they're working on a real cure.
I had a rental PT Cruiser in Florida last week with a much smoother transmission. (Which it needs since the car has a micro-engine, more suitable to a riding lawn mower than a car. Nice going, DCX.)

Sorry to be constantly reading of your problems with your 7g 45....
I believe Kar don is correct and you need to give someone with some "pull" a ride in your car to experience your problem first hand.... I'm experiencing none of these shifting problems you report and if I did, I certainly wouldn't "live with it".... In fact my wife or I haven't any complaints what so ever about the tranny in her ride.
Sounds like you obviously have a faulty tranny and should be seeking replacement.

I do feel the "bump from behind", but I'm used to it now, doesn't bother me. The only thing I do notice is that it feels like it starts out in too high of a gear when you take off, like you press the gas and it hovers at lower rpms for a while then starts to rev(slowly), but still accelerates pretty good. I have to give it a lot of gas right away from take off for it to start out in first and actually rev quickly.anyone else notice that?

yea i have had the same problem for over 2 years. i give up on getting crap fixed. they wont fix the tranny, the pano roof which sounds like a creeking old boat, or the lump in my seat that makes my *** numb. They think its all fine. My lease is up in a while, probably no more MB for me. especially because they cant even figure out how to get the preset scrolling right, even on the new S!
There is a way to reset the adaptive tranny, something with mashing the gas with ignition on. Do this once a week and it helps.
I also notice the car hates downshifting in general at low speed. Going around corners in 5th gear? come on.

I wish I had left the bump from behind thing alone. At least that disapeared when the car warmed up. I really hope they are still looking for a solution to the 7Gs gearing/programming inadequacies.

HEY- Looks like I have 7spd issues...
Driving a little spirited through town and had to stop at a red light. Made my left turn and nothing... car was bucking and wouldn't pick up. I let off the throttle and then feathered it back it... CLUNK... then it went... This is a known issue???? HOLY COW??? That is a bad problem to have... good thing I wasn't crossing against traffic as I had the green turn signal...
Is my issue the same as listed? It seems like it may be different. It shifts okay... but felt like I lost the trans.... for a second or two????

Back in the shop... 3rd time for transmission. They say there have been some additional patches/fixes released for the 7G, and that "Don't worry. We can fix it for good. We're gonna call NJ tomorrow & get permission to replace a couple of things & then re-flash it. It will be fixed & you'll be happy. Period."
Hope so.
Hope so.

I have also experienced similar problems with my G7 after I had some transmission work done due to the car not shifting at all. It would go into limp-home mode, but after turning the car off it would re-set and be fine. I can't find my paperwork at the moment, but I recall they changed some valve, etc. Now I have rough/inconsistent shifts from 1st through 3rd gear, 4th through 7th are silky smooth, as was the entire transmission when the car was new. It also downshifts rough and when I slow down to a near stop it can't seem to find the right gear when I accelerate. I haven't gone back yet to complain but will as I want my car back the way it was.
Thanks, Konig, for posting some possible cures. We'll see if this helps mine...
Barry, let us know what happens once yours is back from the shop with the "final fix".

FYI: Anyone who is experiencing repeat problems with the 7G should request the assistance of their regional MBUSA Service and Parts Operations Manager (SPOM) who, in turn, should get the MBUSA Electronic Diagnosis Assistance Center (EDAC) to open a case for satisfactory repair.

I've had this same problem for almost 2 years now also. They've tried everything including changing the transmission, then changing the value body in the new transmission, s/w upgrades, replacing the pan (got it home after one repair and next AM had 2" round fluid leak on my garage floor). I'm fed up totally with this tranny.
Mallard, I know you are in Austin, I've been going to MB of Georgetown w/no luck. If you get your issues fixed (which are pretty much what I'm having), please email me so I can talk to the same service advisor at whichever dealership you go to.
Lately, I will occasionally get into a state where on deceleration at about 800 RPM, I will get a hard (and I mean hard) thump/jerk and it is completely recreateable until I turn the car off and on again. But it does not always happen after I restart. Anyone had this?
I'm at the point where I'm going to give them one more try at fixing this thing otherwise my lawyer will be sending a lemon letter to MB, and I want a new car!! Anyone try this already? And by the way, if you tell them you want someone at MB to be involved and have a district rep call me, they pretty much have refused my request in not so many words, but they always tell me that they are handing it, etc.

Picked up my E-500 this morning (Tuesday). (They’ve had it since Thursday Night 5 PM, and called me every day with an update.) Here’s a list of the latest trans fix to eliminate the rough 1-2 upshift, and the very late final downshift into 1st which resulted in a slam into 1st when leaving a stop sign:
------------------------
Perform Autom. Trans Elec Func Diagnose
1 220-270-14-06-28 Valve Gear
1 251-271-00-97 Pipe
10 004-990-75-12 Screw
6 004-990-35-12 Screw
2 900-989-00-95X Brake Cleaner
1 220-271-01-80 Gasket
2 129-490-00-44 Bracket Exha
4 140-990-07-50 Nut
12 001-989-45-03-10 Transmission
Use actual Punch Card Time as operation No. 965WMB00
Autom Transm Electronic Shift Adaptation 965WMB00
-----------------------
I have no idea what they actually did in all of the above, but I can tell you I’ve been driving it on and off today, and all the shifting has been smooth, both up and down, with no rough shifts. So far today, I am a happy camper, not thinking about a Lexus next time. If the tranny stays good, these guys just saved MB a repeat customer.
(I didn't "Lemon Law" the car because MB was working on a solution to the 7 speed problems which seemed to manifest themselves about a year after delivery... and you have to give them a chance to come up with a fix. I'm just glad they stepped up and admitted there was a problem with some of the early '04s, and did the right thing.)
Keeping my fingers crossed.

------------------------
Perform Autom. Trans Elec Func Diagnose
1 220-270-14-06-28 Valve Gear
1 251-271-00-97 Pipe
10 004-990-75-12 Screw
6 004-990-35-12 Screw
2 900-989-00-95X Brake Cleaner
1 220-271-01-80 Gasket
2 129-490-00-44 Bracket Exha
4 140-990-07-50 Nut
12 001-989-45-03-10 Transmission
Use actual Punch Card Time as operation No. 965WMB00
Autom Transm Electronic Shift Adaptation 965WMB00
-----------------------
I have no idea what they actually did in all of the above, but I can tell you I’ve been driving it on and off today, and all the shifting has been smooth, both up and down, with no rough shifts. So far today, I am a happy camper, not thinking about a Lexus next time. If the tranny stays good, these guys just saved MB a repeat customer.
(I didn't "Lemon Law" the car because MB was working on a solution to the 7 speed problems which seemed to manifest themselves about a year after delivery... and you have to give them a chance to come up with a fix. I'm just glad they stepped up and admitted there was a problem with some of the early '04s, and did the right thing.)
Keeping my fingers crossed.

Keep an eye on it, when they changed my transmission it seemed good for 1-2 days and then started up again....
