Draining the torque coverter on a 722.6 box

[cws196]

Planning to change the ATF on my brother's S203 this weekend, and going to empty/flush the TC as well. Few questions...

- when you disconnect the cooler feed pipe from the TC, how much force does the oil come out at (from the TC) - ie do I need to put a funnel or pipe up to the hole to catch the oil, or is a drain pan underneath sufficient?

- anyone know what the torque rating is for the banjo bolt on the oil cooler pipe?

- any reason NOT to use Febi ATF oil (approved to MB 236.14) which is far cheaper from ECP, compared to the MB fluid?

Thanks-in-advance

1. Not a huge amount of force. A bucket, or measuring jug would be a better idea than a pan though, as it does spit etc.

2. WIS says 5Nm then 90 Degrees, but I would just use common sense on the tightness.

3. No problem using febi oil - Its most likely the same oil as MB, the bottle is the same.

Brilliant - thanks for that.

Be careful. It came out like hell on my w203. Don't know if yours is same box but I'd seek making up a banjo and piece of old pipe next time. Also didn't allow her to run for the suggested time. As soon as fresh atf started to appear I shut her off.

I used atf from Smith & Allen. Great firm to deal with. Used them for years.

Just to close the thread, did the ATF change today and held-up a large funnel over the TC hole-it did indeed spurt out, but the funnel caught it all and also allowed me to drain it in to bottle at the same time so I could measure how much fluid had been pumped out. After three flushes of the TC the fluid went from thick black to opaque red.
