Automatic Transmission leakage 850 1994

Today I have refilled with 0,3l of ATF. Suspecting a possible leakage I have jacked the car (850 GLT Aut. '94) and I have realized the tranny sump was wet, not leaking drops in the ground but wet anyway. The leakage seems to be located at the seal between the engine and the transmission. The car has 106.000 kms (66K miles)

I know, the next step is to see how many kms are needed to the next refill to asses the possible problem.

I would be very grateful with any opinion of people who have experienced problems with the 850's AW 50-42 transmission. Is usual leakage in this tranny? Is it a signal of an imminent rebuild/overhaul? Are rebuilds usual? at how many Kms/miles? How much cost aproximately a rebuild with the only change of the damaged seal (supposed it is the cause)?

Does anybody know any web page with detailed information about this model of Aisin Warner transmission?

Thank you very much in advance!

    Could also be rear main seal

    I think that's typically where the rear main seal leaks from. Are you sure you are leaking ATF?

      I would be grateful if can you explain me what exactly do you name "rear main seal", I mean, I am from Spain and often we name the same things different than you. For example, we dont use "aut. transmission" we would use "aut. gearbox". We used to understand by "transmission" the differential or the mid-shafts between the gearbox and wheels.

      I have seen it is very usual the expresion "rear main seal" in US but the exact translation has not sense for me. I understand about "seal" but "rear main" does not help me to know what is the seal you refer. Is it the seal between the sump and the block? Between the aut. tranny and engine? seals of the mid-shafts? a seal that belongs to the aut. tranny?

      Thanks in advance.

        I am living in Mexico and am about to have the rear main seal replaced on my 95 850 GLT Aut. (128k). Another term for this part in English is the rear crankshaft seal. In Spanish (at least in Mexican Spanish), it is called the "reten trasero del ciguenal".
