old manule tranny on 1996 318 help

The problem would be less.If you have a ecm programmed for a automatic,it will not react the same with a 5 speed manual,the whole system would be out control.If you want a 5 speed on the car,not a problem,have the ecm reprogrameed to a 5 speed.the dealer can do this if you talk to the leed tech and they can down load a new program into the ecm.This way you can use a 5 speed from a nother car/truck,mate it to the motor and run the system with the sensors and it will all work as long as you have the complete wiring harness for a manual tranny motor.Mrmopartech
