Porsche 944 Overfilled differential due to leaking automatic transmission
Porsche 944 Problem
Automatic transmissions can leak internally and cause the automatic transmission fluid (ATF) to mix with the differential oil. An overfilled differential and/or a low fluid level in the ATF reservoir is symptomatic of this. If not repaired immediately, the transmission will fail; the pinion seals will also need replacement.
