Today while driving my 1986 328, I missed a shift, Now, I cannot get my car in 1st gear and reverse is very difficult. It is not the clutch as I have the same problem if the car is running or not. What happened? Did I bend something? Did I just knock it out of adjustment? How do I adjust the linkage? I assume it is all done my taking the transmission pan off and adjusting there. Anything else to look for? Possible parts tp replace while I am down there? Help appreciated!!!
