After reading new (to me) threads on this subject I decided to see how closely my car's system comes to the Functional diagram for engine 617.950(300SD), that I downloaded from PeterSchmid.com In short, not even close. Yet all the doors and the trunk will lock and unlock; the engine will shut off;
however there is minimal climate control (the usual CC servo problem). The transmission seems to work quite well.Downshifts are absolutely smooth. Going up, there seems to be a slight delay in getting from 3 to 4 (Flaring ?)
also noted that holding the throttle absolutely still will improve shift quality.
a little too much throttle will delay all shifts too much(IMHO).The tranny has been rebuilt and the engine is in great shape. I will attempt to send the diagram of the present setup hoping someone will suggest some improvment that I might make. I hesitate to make too much of a change without some learned advice for fear I will make a giant step backward. I'M not the sharpest tool in the shed. Hope I did the picture right. Willie (Poor Soul)
