Many good Mechanics have told me and its pretty obvious that ZF trannys run great BUT..their biggest weakness is that they dont handle heat very good and that the cooler they bring many mechs have told me is WAAAAYYY to small for that tranny. A friend of mine who's Porsche guy told me that these trannys can last a long time if you can get them to run about 50 to 60 degrees lower than normal engine Temp. So thats probably off the 180 mark try to get it down to 100 or 110. I kind of thought about it
. The man does know what hes talking about because He has worked on Alfas and Porsche's pretty much all his life. Hes a very nice man 60 years old. SOOOOO I tried something to prove myself and pass it on. What I did was I pulled the tranny thermo off and unscrewed the brass nut or the actuator itself I had to heat it up on my stove with water to get the little metal wire if you will to come out which opens the thermo.I measured how far it came out cut a nail put in there to keep open at all times screwed brass nut back and installed it back in engine. I went for I ride..AND HOLY ****!!!!
What a Difference!!!
Talk about smoother Shifts!!
BTW I also made sure I flushed the cooler itself to make sure it was clean inside before I installed it. Tranny definetly runs a little cooler NOT cold but warm although the fan will not kick in until it reaches 180+ but as you drive the airflow really keeps it good dont have to worry about it running to cold because engine itself keeps it warm. Just an Idea to Pass on. I told my friend about it He Just smiled.
