Q&A

In P, N, my idle fluctuates R the car acts like it's in neutral D, S3, S4, and 2 work fine. But if I disconnect the shift linkage at the shifter lever and put the lever into D and then manually pul the cable to the tranie into R reverse works fine but then if I put the lever into R wile still leaving the tranie in R the car goes into neutral it's like the computer is telling the tranie that R is actualy neutral or park. Help!
