Tip 4: don’t lift off for downshifting or up shifting when shifting manually. The computer got you. Don’t confuse it. What other tips do people have? P.S. check out my 10 tips for bulletproof engine: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cGTu1VkR60I.html

I don't agree with two of your tips, the first one is not to change gears manually - if I let it change itself, then it shifts to a higher gear with which it cannot be accelerated, so you have to wait a few seconds to change the gear, and then it's too late, so do it manually I always keep it in a lower gear so that it spins, another tip is to relax the pressure on the gas pedal: then the gearbox has to slow down or speed up the rotating parts through friction, which wears out those friction surfaces and thus the entire gearbox, so when shifting from a lower to a higher gear, you need to ease off the gas ( don't take your foot off the gas) so that the difference in revolutions is as small as possible, when changing the gear to a lower one, increase the gas a little in order not to brake the engine and thus wear the gearbox.I have been doing this for years and when changing the oil in the gearbox, the oil is almost completely clean

I ROFL at tip number 3 🤣 Quote of the day, “It’s not your gf leg” - accentoncars 😂

@ginco_bnz 2 месяца назад

That’s what the green up arrow is for when you’re in manual mode, it tells you when the car would shift for maximum fuel economy. In a non-AMG also “manual” shifting is really just a gear limiter, the car will not listen to your shift commands anyways if it doesn’t want to be in that gear.

I believe the 7G trannies were link connected to the transmission. I know my 2004 SL500 was. My 7G-plus that I now have is completely electronically controlled.

@MacDaddyThis 18 дней назад

%100 agree!!! Do NOT keep you hand on the shifter!!! Auto or manual. These are NOT shift by wire as stated. There is a shift locator module in the floor shifter that will fail prematurely because of minor movements over time. You may physically be in drive, but as soon as that sensor looses position for a split second, limp home mode... 😭

@gurumeditation8911 2 месяца назад

The 7G is a workhorse. Just keep the maintenance schedules, repair small issues immediately, keep your hands off and let it do it's own thing and it will serve you well for a lifetime. These will never pperform like DCT's, so it's pointless to try and push them.

@wernerdanler2742 2 месяца назад

I had an 01 e320 until about a year ago. It shifted very smoothly, and you could never feel it. However, if you stepped on it, even just a little, it sounded like someone shifting a manual geatbox. Kind of a clutching gear change sound, but you didn't feel it. I thought it was the weirdest automatic gearbox I have ever had, but kinda cool. Is that normal for these?

@JettaRedIII 2 месяца назад

In addition to the mileage requirements for changing tranny fluid, there is also time limits. Some cars have low mileage, but are beyond the recommended time limit for changing. For example, my 2015 SL400 has 45,000 miles. The maintenance manual says to change the tranny fluid and filter every 77,500 miles or five years. Not realizing the time limit, I just recently changed the tranny fluid (dealer service) with the car being 9 years old.

What about long shifts? I dont feel like my transmission is as snappy as the clip you showed on this video

@AccentOnCars 2 месяца назад

AMG transmissions are snappier than non-AMG. If your transmission doesn’t feel like it’s slipping and operates well otherwise, then it’s probably just fine.

@jdm542 День назад

i have the 2 - 1 downshift clunk, like a loud clunk sound when coming to a stop, i have been going crazy about to do a rebuild, have you heard of this?

@AccentOnCars День назад

Most likely it’s one of the issues I talked about in the video. 2-1 can be a bit rough at times but clunking is not a good sign.

MCT AMG 7G’s can feel jerky on down shift as a general characteristic.

@AccentOnCars 2 месяца назад

Haven’t had MCT equipped car, I have heard later year ones are smoother. Is that true?

@goddesseddog 2 месяца назад

it is NOT shift by wire! as your video shows, there's a mechanical link to the transmission. also, 5G tronic was introduced way back in 96 in the W140

@AccentOnCars 2 месяца назад

Good catch. I sounded confusing about dates in the video. I was talking about the dates when 5g and 7g made appearance in w211 chassis specifically. Otherwise, 722.6 was introduced in 1996, you’re right. Regarding shift by wire. My point about not resting your hands on the shifter is more true about transmissions with mechanical connections. My car is equipped with 7g and it is shift by wire, isn’t it?

@phillm156 2 месяца назад

Great advice. The same can be said for manual transmission guys who rest their hand on the shifter. You are wearing out the throw-out bearing. What I really like about the AMG 7speed is the ability manually lockout higher gears. In sport mode I can use the paddles and limit the amount of gears. It seems to hold each gears longer before upshifting.

@AccentOnCars 2 месяца назад

@energymc22 2 месяца назад

Not true. The throw out bearing is not linked to the gear shifter in any way.

@phillm156 2 месяца назад

@@energymc22 my mistake. It’s the shift fork and collar that will be damaged.

6:28 Can you please explain how did your speed sensor failure manifest itself? What were the symptoms? Sometimes I experience slippage from 1st to 2nd and 2nd to 3rd and rough downshifts uphill or downhill. Not all the time, sometimes it happens when cold, sometimes when hot... I have the 722.6 or 5G-Tronic. Thanks.

@AccentOnCars 2 месяца назад

Mine would get stuck in gear. One time it got stuck in 5th gear as I was merging the highway at slow speeds. It took me ages to build speed. I was so embarrassed 😂 Your symptoms are definitely not good. Definitely could be the conductor plate. But slippage is unfortunately the sign of hardware failures. Get it scanned. Hopefully it doesn’t actually slip and just feels like that to you. I used to have e350 with 5g and ignored rough shifts until the transmission took a cr*p completely. It should shift smoothly.

@deyoviC 2 месяца назад

@@AccentOnCars They can identify slipping by scannig? I thought they need to drive the car. I might take it to a well known local shop that specifies in repairing conductor plates and components. Thanks

@Spidepig09 Месяц назад

@@AccentOnCarswhat were rough shifts like?

@AccentOnCars Месяц назад

Down and up shifts are roughly. Almost feels like clunking noise from under you. Happens when slowing down usually.

@Spidepig09 Месяц назад

@@AccentOnCars man mine shifts like that sometimes but Ive done the proper maintenance since new.. changing the conductor plate helped a lot though. So might be a solenoid.

@Random38346 Месяц назад

7g-tronic jerky when i press the gas when the car it's down shifting automatically I fell a jerk like if I don't give the car enough time to down shift, and the car car has to down shift abruptly

@AccentOnCars Месяц назад

Very likely it’s the conductor plate like I discussed in the video .

So if I have paddle shifters I shouldn’t shift it?

@stevanmilenkovic4064 Месяц назад

Noone asked nor mentioned is it recommended to change it to N when you are waiting, for example for a red light. I practice to change it to N when I know I will wait more than 10,20 seconds, because of heat generating in torque converter. Otherwise, when I am in dense traffic with short stops, I don't move it from D. Someone says this should be done, someone says not, but my logic is why to torture it when you know that you will be at standstill for half a minute or minute, change it to N to let it "relax"... I see you are well informed about those stuff, i will like to hear your opinion.

@AccentOnCars Месяц назад

That’s a good question. I put it in neutral only if the stopping time is more than a minute. For example, if the traffic fully stopped or there is a train passing. I don’t shift into neutral on red lights and stuff. The computer does all necessary things for you. Actually, I read that you “hurt” more by frequent shifts from D-N-D as the converter and engines are out of sync when in N, and shifting into D causes a minor slippage until the clutch locks. In a nutshell, don’t overthink it. Enjoy it.

I have a 9g and sometimes gears get stack on 2nd gear or 1st! Sometimes there is different symptoms like clutch slip feeling. I usually switch off and back on again and gets back to normal. Millage is 72k. I am suspicious about speed sensor but will risk a transmission oil and filter change and see what happens. Just waiting for better weather in uk lol😂 when I asked mercedes about conducting plate they said it needs to be programmed and they wouldn’t sell it to anyone but there authorised repairers. they sell reconditioned units so they want old one back.

@AccentOnCars 2 месяца назад

Get it diagnosed for sure. Changing the fluids may help. Give it a shot it you are willing to try. And that’s right, I got mine done by an authorized independent shop too.

@seryil4806 2 месяца назад

I can’t believe you done the head bolts and all the other work but didn’t attempt gearbox. Makes me think shell I just get it done 🤔

Sounds like transmission oil low. I once changed my transmission oil, and didn't put enough in, it slipped 1 to 2 gear. I topped up and issues went away.
