that's how i did it, one liter at a time to make sure the pump doesn't run dry.

shivi1345

so just really quickly to be sure.......

we agree that ATF 4134 is the best stuff to use?

you guys say also it's a pain in the as* to do, so how much would a guy charge me to do it?

thnx

What I meant was....what if you dumped all of it. Let the pump go dry ( but don't let it keep going once flow stops ). Would that vacate all the fluid so it wouldn't take 13 qts.?

Dingleberry

your idea is creative, but flawed. only another fluid(the new stuff) can push the old fluid out of the converter and trans cavities. therefore, by trying to do that, you would not only cause excessive wear on the pump, but you'd still be left with old fluid in the converter and trans system. as splinter mentioned, there is no way of draining all of the fluid short of disassembling the entire transmission. the only way to get the old fluid out is to literally waste an extra 5-6 liters.

mleskovar

That's why I asked.

crazypotato

I doubt the fluid pushing theory. It is probably diluting the contemplation every time you fill and drain. However, it is a way to flush out all the dirty fluid.

mleskovar

They actually have machines that do "fluid replacement". Often wrongly called a "flush", there's no pressure other than the pump (thankfully or you might blow some seals). They are hooked up in line to the trans cooler. I don't know how much fluid it takes with those though. I've heard you need to activate all the shift solenoids to get a 100% replacement.

shivi1345

so do I need 8 or 13 liters of this stuff?

also, is the 4134 safe for the M271? (m111power posted about it earlier))

Glyn M Ruck

Shivi - The Fuchs 4134 is absolutely fine for the 722.6 transmission in your car.

shivi1345

sweet thanks. 10 liters should be good, right?

Glyn M Ruck

Somewhere between 10 & 12 in my experience.

Dingleberry

it took 14 liters to get my fluid looking new again

Glyn M Ruck

I can well believe that. The fluid in the cars that I have helped change was still clear & bright in oilco terms. Had hardly changed colour. I'm 4000Km off of my 60,000 Km fluid flush & change. My fluid is unstressed. I will let you know how it goes & what it takes.

Hello everyone. I have a w203 C220 with nag1 (5 speed). I would like to change ATF oil.. my car mounts atf MB236.10. I would ask if I can mount the DEXRON VI ( http://lubricants.petro-canada.ca/re...72&language=en ) or could cause damage?
thanks

Glyn M Ruck

Dexron VI is the wrong fluid for Benz 722.6 & 722.9 gearboxes. It has the wrong frictional properties & will lead to failure of the multi wet-plate clutches.

Only use fluids meeting 236.10 or 236.12

TONY220

Thanks for the reply.
I ask because in the technical-date, "Application" ( http://lubricants.petro-canada.ca/re...72&language=en ) they say: "It is fully back serviceable for
DEXRON ®-III (H) III and IIE applications." ? Give wrong indication?
I want an oil that reduces the slippage of nag1.
thanks so much for the friendly and fast responses

Glyn M Ruck

No Dexron formulations are suitable for 722.6 & 722.9 - 5 & 7 speed automatic transmissions.

TONY220

ok but my car is w203, C220, 150hp, NAG1 = (722.6 .... is that correct?) 5-speed automatic transmissions. Transmission nag1 (5speed) is 722.6 or not?

thanks 1000 for reply

Glyn M Ruck

The 5 speed auto transmission fitted to your car is a 722.6 - I have no idea what NAG1 is???

TONY220

so I put in my transmission(722.6) the Dexron 6 .... right ? thank's

CAR: W203, C220 SW, 150HP, AUTOMATIC NAG 5 SPEED GEARBOX, year 2005 restailing, trasmission 722.6

Glyn M Ruck

No DEXRON 6. Only use fluids meeting 236.10 or 236.12

LILBENZ230

Use Fuchs Titan 4134 available for order online from rmeuropean.com.

Glyn M Ruck

Tony - I don't know where you are? Canada? Your car is a 5 speed auto C220 Diesel - Yes? Then it has a 722.6 transmission.

If you can't buy the Fuchs Titan 4134 fluid where you are then buy the fluid from your dealer.

Please complete your profile so we know where you are.
Good luck!

Glyn M Ruck

Matt - have you any idea what he means by NAG or nag1 Is that speak from your side of the pond anywhere???. I'm not familiar with it - it can't be "Naturally Aspirated Gasoline" because the C220 is a diesel here???

We have a language barrier - trying to help. From my international days I can usually decipher.

TONY220

I am Italian, I'm not good at speaking English .. : ( My car is diesel.
it is strange because the nag it mounts dexron3 of of varied marks... agip,castrol,mobil1,valvoline etc..
I do not understand because dexron6 is not suitable.
attention, the technical cards of the dexron6 say that it can replace the dexron3 dearly.I am confused...

my car uses: "Castrol TQ-DIII or TQ-D, Agip DexronIII or ATF II D , Tamoil ATF II D." -> here because I do not understand in order which reason cannot replace with dexron6
