question about transmission flush

2499 Views 28 Replies 8 Participants Last post by  cowboyt
I was curious if someone has made a machine like a pressure bleeder that would flush the transmission out without having to run the engine while doing the procedure. was thinking of trying to build an attachment from a old filter from a 722.6 tranny, some glue and pvc fittings. I just didn't know if the pump would allow the fluid to go through while the car is stopped, or would it be unable to go through the cooler, and running the car is the only way.

I have 2 cars that seem to need a change. My car appears to have never had the trans fluid changed. The black tab is still on the dipstick tube. Seems to shift fine according to the mechanic that did the PPi. My grandma's car needs a change as well. I know that it hasn't been changed for about 80k for sure if not more. She and I were talking about it, and she wants me to do it. The dealer prices were well over crazy. Also, the one dealer for sure is still pushing the 'sealed for life' carp.... grrr...

I have looked at the idea of using blocks like that. But as I want to bleed the brake system while I have it up, I've been looking to take all 4 wheels off at one time... Setting tires on boards doesn't seem to be compatible with that idea.
I have eight blocks. If I need to take off wheels, I just put the blocks under the jack pads points by lifting from the front cross member, differential or factory jack holes with grade eight bolts.

One advantage I found with blocks is that I can safely work on my sloped driveway if I need to. Changing fuel related items is one example I don't want to do inside the garage.

Whichever way you choose, be safe.

It's a good point. Thank you from bringing that up. The stands I was referring to have a 12" x 16" bases and are rated fro 24,000 pounds a piece. They're from my days doing brakes and suspensions on semi trailers. I used them on big machines, etc. The blocks you have however have a larger surface area at the top. There may be some added safety in that. But, that's nothing I can't change with a welder and some 1/2" x 6" x 6" plate...

For those looking in Alberta and Saskatchewan, and maybe BC, UFA Petroleum has Shell ATF 134 for $6.67 cad a quart.
I am about to do a complete transmission fluid flush and I have seen on other threads members talking about using 236.10 in old transmissions (mine has 220K Km) instead of the 236.14. Could someone confirm that this is better suited for old transmissions than the new upgraded ATF 236.14 despite the fact that MB claims 236.14 is backward compatible?

I have as of yet to find anyone stocking the 236.10 fluid. Might it be better?? Maybe...... But.... Unobtanium....

Mercedes Benz 10 Liter MB Spec 236.10 Red Automatic Transmission Fluid Oil ATF | eBay

10-Liters Mercedes Automatic Transmission Fluid (MB Spec 236.10)

I'm currently using the Meyle 236.10 in my '03 S600 TT. As you'd expect, it works beautifully. I will also use it in my 2005 E320 CDI (722.6 transmission) soon as I get a chance to do that car's tranny service.

I use 236.12 in all of my transmissions. Don't know if it's any better, just my choice.
Nothing wrong with 236.12, either. I currently have Febi Titan 236.12 in my '03 S430. Judging from how well it shifts, the transmission likes this fluid quite a bit.

Same here, 236.10 fluid is not available.
I have used MB 236.14 in my cars and all are going well.
I've used 236.14 (specifically, Shell ATF 134) in the 5-speeds as well, and sure, it works great. The last one I did that on was a 2003 C230 Kompressor with the 722.6 transmission. Guy's scootin' around all over town.

It's neither "better" nor "worse"; it's simply a matter of transmission feel. Since the 236.14 fluid does have a slightly lower viscosity, your shifts will feel a little more firm. This is said to actually be good for the transmission. The 236.10, being a bit higher in viscosity, will tend to have slightly smoother shifts. Many people prefer this (I'm one of them).

Any of the three--236.10, 236.12, or 236.14--and any mixtures of these three--are correct for the 5-speed 722.6 transmission (not so for the 7-speed 722.9 transmission--that's 236.14-only). All three fluid types are compatible with each other, so no worries there, either.
