Porsche 944 Car Problems

Overfilled differential due to leaking automatic transmission on Porsche 944

Problem Description and Solution

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.
