I think my cars in "limp mode". I can drive for 30 seconds then it "stalls" seems to happen to a lot of people. I'm at 177,000 KM other people are at less with the same issue. Should I shop around? Quote from Dynamic Transmissions, Toronto Canada.

My indie specialized in Sprinter and MB and since many Sprinters and MB share the same transmission, he has a lot of experiences in 722.6. He did the pan flush for me last year. He was super clean and the pan flush was excellent. I will call him tomorrow and see if he does transmission rebuild.

Your w209 is a 2003 so it has the MB supposingly "lifetime" ATF. Did you ever change the ATF?

Rudeney

Stalling every 20 seconds is not limp mode. Limp mode is being stuck in 2nd gear, but the car will drive just fine. Is the MIL illuminated? It may be an ECU problem.

bheng

stalling every 20 or 30 seconds? does it give a jolting motion?

if so, check your fuel pump pressure. CEL on or anything?

Rogue-CLK

Never changed my ATF yet just got the car for less then a month, and when I told my dealer about it, he didn't wanna do anything to help me. My dash always had an srs light both red and on the screen, and ESP light was on the screen but not that yellow triangle thing light that shows its off. No actual jolting just feels like it went into neutral. I've already turned it off then on doesnt make it work right away gotta turn it off for a few minutes then start it again to run for those few seconds. I'm assuming its coolant in the transmission cuz the place that gave me that first quote said it was full like to the top (over) I'm taking it to "McNally's" this afternoon to see what he says, got a better quote too $2500 for a rebuild with a 20,000 km 1 year warranty if... That's the issue. Keep u guys updated. Seen this happening in youtube and then didn't post how they fixed it or what was wrong -_-

McNally is supposed to be a very good MB specialist in Toronto.

Please keep us updated. I hope it turns out to be something simple.

First, check to see if you have the Valeo radiator:

If so, you may have coolant in the transmission fluid. If so, that may not have damaged the transmission - you may just need to fix the radiator (replace it with the Behr), then do a full transmission fluid flush.

But again, you say it "stalls". Generally, when talking about engines, the terms "stall" means that it stops running. So does your engine stop operating, or does it continue to run, but you just can't move, as if the transmission is in neutral? If the engine is actually stalling, it's not likely to be a transmission problem.

My car used to turn off after a while. Would have to wait a bit before turning it on again but the same would happen. I ended up replacing the crank position sensor myself and it fixed my issues. Sounds like it may be that but you never know with these cars. It also wouldn't throw a CEL so i ended up figuring out my problem after searching through the forums for a bit. Hope you get your issue fixed without having to purchase a new transmission. That price also seems a bit ridiculous.

Rogue-CLK

That's what I mean, motor still runs. Rpm goes higher but I'm not moving any faster then eventually to a stop.

Rogue-CLK

Well if it is a tranny probably I rather pay $2500 over $4500 any day LMFAO. Hoping its a radiator problem or a sensor. Ill find out tmr morning.

Rudeney

OK, then I would look to this being a transmission problem. Did you check your radiator? is it a Valeo?

Rogue-CLK

Didn't check, ill c when I get a call to go over there, they did say it might b the radiator common problem, but no word yet. If it is a Valeo and that's the problem should I replace it with what u suggested "Behr".

Rudeney

Yes, if you have the Valeo, definitely get it replaced! But more important, if you do have coolant mixed in the transmission fluid, you may not need the rebuild - you may just need a good fluid flush and filter change and all might be well. The coolant really isn't "bad" for the transmission, but it's thin so it doesn't allow for the proper hydraulic pressures and thus results in these types of problems.

Rogue-CLK

I hope your right. That sounds better. Haven't heard anything from them yet ill try tmr. Any idea how much ^ will cost?

Rudeney

The radiator itself is under $300. The labor is about 3 hours, not including the transmission fluid level check.

Rogue-CLK

That's seems alright/reasonable hoping for the best... Hate not knowing what's wrong. CEL's annoy me and cuts into my sleep... -_-

Rogue-CLK

Just got off the phone with Charlie McNally, he says it's the Valeo radiator and tranny, but should I just try to replace the rad and get a tranny flush? And go from there?

Louie D

Defiantly !

Rogue-CLK

I tried to tell him to do that, but he says I need a tranny rebuild aswell :/

Codes came out as:
P2502 gear implausible or transmission slipping
P203B monitor function fault accelerator
P2004 MAF sensor short circuit to battery or reff. Voltage.

Also abs, srs, cel are on.

That's what's on my receipt from the first shop not McNally's

mis3

Is McNally's quote the same, $2,500? Also, what does MAF sensor have to do with the transmission?

At least, McNally is a reputable MB-specific shop locally in Toronto.

Rogue-CLK

Those were the codes it was throwing. I'm not sure if it had something to do with the tranny but guess I'll replace that too, $2500 for everything installed. Not including the new rad, ($400) or a ($200) alternative, it's an external cooling system bypassing the Valeo rad. I hope he's correct about doing both the rad and tranny. I wanna try just the rad and tranny flush first but he's the expert right :/...

mis3

To change the radiator and full ATF flush will run you about $1,000. Radiator $400 + 11 liter ATF, $275 ($25 per liter from MB) + Labour + Tax.

If you do the transmission rebuild and radiator change, the whole job will cost $2,900, not sure if tax included.

If I were you, I would negotiate a better deal for the rebuild and radiator change. Since my w209 is my daily commute, I cannot afford the trial-and-error approach.

On the other hand, I am surprised that this Valeo radiator issue came up after 177k km. I would think that this would come much earlier.

Rogue-CLK

Guess I won't do the trial and error approach, price is without tax. I'm surprised too, I've read that it's a bad/defective rad but it held up till now yay me I guess :/ LOL I get to replace it -_-. I'm assuming I'll be getting new ATF included. Ps mines a DD too, it's been a few days since I've driven and I'm already going crazy... Well since day 1 without a car.

mis3

I would think that the transmission rebuild would include the ATF. You did say $2,500 for everything installed.

On the other hand, the $400 radiator change would not include ATF.

Rogue-CLK

Great. I'm letting them do everything tmr, oh for other people that goes to McNallys they're closed on weekends. I was waiting to see what was wrong with my car (Dropped off car on friday) and no answer LOL.
