Re: BW35 Trans Fluid Leak/noisy reverse gear

my workshop said, the oil is not draining back from converter. (?)
And if that is the case it can only mean that it's leaking externally with the fluid at the normal level, which shouldn't be the case so soon after a rebuild.

- since a few weeks, the reverse gear of my BW35 sounds very rough and loud.
If the noise is only apparent in REVERSE then it could be the gearset. (But that's obviously a guess without the benefit of actually hearing it).

- I must fill up auto trans fluid now every 80-100 km, because the trans starts to slip.
If you're going from the correct level down to the point where the transmission slips because of low fluid in 80-100km that needs looking at as a matter of urgency.
Hi dear Harvey,
I am glad, that you response,
yes, the auto trans was starting to leak (a little bit) short after rebuild. during the last time, its becoming more and more.
Reverse: example: if I start the car (standing over night), put the reverse gear in, it sounds rough and by trying to drive in reverse gear backwards, the transmission slips the first 1- 2 seconds.
Infomation: ist a NADA car but have the dipstick/filler tube inside the engine area like the S1 P6B‘s
during test drive with correct fluid level (as described in original workshop manual from 1969) the transmission start to slip a little bit -
after circa 1,5 hours of driving (during D drive). I parked the car, checked the fluid level and the dip stick was dry and clean, some little smoke was coming out oft he dip stick/filler tube.
after filling up the fluid level again, I could drive home again without any problems. so, there is now a massiv oil leak, because it‘s also losing some oil when the engine is off.
URGENCY: yes, thats my problem. there is no workshop, mechanic, garage which is able to repair my BW35 here in austria. do you have any idea/contacts/references to a solid workshop in the austrian/german regions for a perfect, correct rebuild of my BW35?
I have a spare BW35 (from a S2) in my basement. I bought it as a "before running/working" transmission 2 years ago.
How is it possible, to test/check this Auto box before putting into the car? Is there the need, to rebuild an "auto box" which was not running for 3-4 years?
thank you for your advices.
kind regards, richard
