Hi,
is it possible for my front pump to leak after its been overhauled maybe 5000 km before to do B3 reverse job done? Recently I just changed valvebody and then this somehow happened didnt even get to drive it much, as I had problem with leaking fluid from trans cooling line cut and warped oil pan leak(now fixed).

What could cause this MASSIVE (like almost splashing out of TC area)leak? And also it refuses to engage reverse, could be due to lost fluid though,(drive is OK) and when i try to put some gas in R it wont do more then 2k RPM asi if it was blocked by something. Also it has noise in N and P (more then usually had) just recently before or with the front leak incident.

thanks for any help

believing that you checked the obvious - which is torque converter drain plug not loosened out.

The noise you hear is the system running low on oil - specially if you have a splashing leak.

Well, noone touched the TC drain plug recently, could it be it somehow leaks on its own?

Hello I have another update, (i didnt get to lift the car yet so no pan inspection yet, but I bet there wont be anything):
- took a ride in the car just to fill some fuel and first start it was leaking almost as fast as the cooler tube (half a liter in about couple of seconds) would if it was disconnected in P and in N also, I gues in gear it stopped totally even when cold as ice
-reverse is definatelly blocked by the one way clutch - it doesnt go forward on an incline, and if I want to move the car in the way reverse shoud go it is blocked!!!, when my B3 clutches were gone it was like neutral so this IS NOT a tiny bit similar, is feels like it leaves the freaking parking pin stuck in.
-Forward gears ALL AS NICE AS CAN BE, even 2nd gear IS BACK!, all smooth all fast all without flaring all not even noticable RPM are exactly as they should be absoultely no slipping
- Kickdown somehow doesnt work and even if I want to force 1st gear with B selector it wont downshift

Now tell me what in the world would lock my reverse and force the transmission to bleed itself from the front?

I guess this is another 1/5000 scenario which I dont really have patience for...

I wonder why the car thinks I am happy when it challeges me with the hardest and toughest challenges it can throw at me. I am no mercedes GURU trained specialist.

So now what do you think guys?
