So , when I was replacing the secondary cats a week ago at porsche workshop we noticed a red risidue at the transmission and these 2 days the transmission feels strange and streesed.. Sometimes it clunks but not hard like before but its streesed . Also it doesnt shift good , what I mean is : I was driving in traffic at 40-60 kmh and the transmission is a 5th gear and rpsm at 1000-1200 rpm . The car feels like stalling I should mention that I changed transmission valve a monthe before , oil , filter , driveshaft , fuel pumps , spark plugs , igntition coils , everything !!! After some research on this red rissidue I found out that its a seal in the torque converter which leeks .. The seels is like 30$ at pelican parts but the hard part is droping the transmission and replace it ! Now the question is , does this oil come from transmission or as I read from coalant pipes or steering wheel maybe !? Steering wheel is noisy! Any opinion is apriciated , Thanks

 

The coolant color is "pink" and thin. The power steering uses hydraulic fluid that is "light brown" and thick. The transmission fluid is "dark red" and thick. From what you are describing, it sounds like transmission fluid
