[Diki]

can you also help me identify which box is in mine WDD2120022A065207 is chassis number TIA

Hard to be 100% on this but I think the oil pump is driven off two pegs on the input shaft of the gearbox. They are easy to break if you don't fit the T/C mounted correctly on the shaft, rather than trying to fit the box with the T/C already fitted. If you have sheared the pump drive that may one of the issues.

You have a 722.646 transmission according to your Vin#

I have a box saved on ebay but not sure if it will fit

That's the part number from the casing, you need the 722.6 number stamped onto the machined flat section on the housing

You won’t get the tc out just by removing the sump!
It isn’t a massive job to drop the transmission out complete, but bear in mind it is heavy. Surprisingly heavy. If replacing the tc I recommend standing the gearbox (with an assistant) on its tail, and dropping the new tc down vertically. You must ensure it goes fully home into the bellhousing. If you don’t it will shear the oil pump drive tabs, and that’s a whole box strip to replace. If I had a pound for everytime I had to replace an oil pump because another mechanic had messed up fitting a torque converter to a 722.x transmission I’d have, well, about eight quid, but you get my point...

tach bounce can be a sign of tc failure, but in my experience a light vibe, akin to crossing a cattle grid just after a gearchange is the most common symptom

722.9 Auto box problem. No drive at all. Any help appreciated. | Engine

Hi Guys, I know this has probably been discussed several times but I'm getting confused with everyone's opinions on the problems they have had. I haven't got any experience with Auto boxes except taking engines off them. I drive a C220 2011 with the 7 speed Auto with stop start but yesterday at...

I took the gear box off but like you said I don't think I had all way in as the box now has an oil leak, which it hadn't before,

Hi William is that thumbs up mean it will fit lol

But surely they can be integrated with another if you have the box and the converter ?? cos its proving pretty hard to find said box

 

[Jobsworth]

The ratios vary, and the wrong box won’t work in your car because the electronics all monitor the wheel speeds. If it’s not as expected it will stay in limp. If you fit a secondhand box the numbers must all match

 

[Trickythemerc]

Why not just go for a rebuild of your own box and save yourself a load of problems ?

I saw a video of this being done with the box standing vertically in a stack of tyres , the margin for error getting it lined up was quite small and so doing the job horizontally meant it was easy to tighten the bell housing with the alignment out = pump damage.

Can't find the video , sorry.

Repeating myself here, but you are still searching for the transmission code and I gave it to you in Post#3 above.

Using the Vin# you supplied, the transmission code is 722.646 07 814224.
