2001 208 CDI Automatic Transmission Fault

[Tinderbox]

Sorry if this has been discussed before but a search did not bring it up.

The auto transmission on my Sprinter is failing on me. It does not seem to be mechanical but electrical. It will not stay in Automatic. Keeps going into Manual and then is reluctant to shift when I select with the gear stick.

After some research it seems there is a common fault with the Orings in the 13 pin connector (722.6). They leak transmission fluid, it gets into the 13pin connector and interrupts the signal. This sounds like a possibility but i am just putting this out there in case I have got it completely wrong and I don't even know yet if my van DOES have one of these 722.6 connector thingie. Not been under to look as it's wet and dark.

Any help much appreciated.

You need to get the transmission read for fault code's...know anyone with iCarsoft or or other scanner?

No I don't. I am reluctant to take it to a mechanic before first getting half an idea of what might be going on as I'd rather have a bash myself. A quick shufty on ebay and it seems there are various versions of Icarsoft. MB, LR, V1.0 & V2.0. As mine is a 208 CDI 2001, which do I go for? I don't mind buying a svcanner but I need the correct one. Do I?

With the 722.6 box, you can check the fluid level through the fill tube with a dipstick (Ebay if there isn't one there).
You would also see wetness around the connector (Merc call this a 'pilot bush') if it was leaking, as the connector has a weep hole at its base (early connectors did not have this).

First thing you need to do before getting a code reader is identify what type of diagnostic port you have. At 2001 some were OBD2 and some were 38 pin round connector. OBD2 if fitted will be down by the steering column probably below the parking brake release on the flat panel above the pedals (it will probably have a cover on it). A 38 pin one will be under the bonnet.

Parking break? You mean hand break? Stearing column? Sounds like you are talking US and not UK...but thanks for the info.

Yes, that's what he means. Confusion is that on Mercs, the 'hand brake' is foot operated

Indeed. That's why I call it parking brake.

A 208 CDI T1N Sprinter doesnt have 722.6 it has Sprintshift trans. This is a fully automated manual trans with electronics controlling hydraulic actuators for shifting and clutch. Only the 5cyl Sprinter had the 722.6 option in that T1N era.

This sprintshift trans is a total can of worms. Google it lol.

The most common issue is the control relays, then the pump brushes. You need Star diag or similar pro scanner to read the codes. And quite frankly anyone running sprintshift should carry star diag at all times and learn how to use it.
