ECM numbers for a 99 with a manual trans

Recommended Posts

I am wondering what ecm number I will need to get since I have convered my 99 from an auto to manual transmission? I know that it will have to be out of a 99, but I am not sure how many different ones there are for the 99? Also since I will have to get the PCM could I get both from another year? Thanks for any help, Jon.

Sorry to say there is roughly 44-46 different ECMs for the 98.5 to 2002 series for each year. Federal emmision pack, Ca. emmisions pack, 5 speed, 6 speed, automatic trans, etc. Best thing I can say try looking for a ECM rebuilder. Because anything you find in a wrecking yard will require you to reflash the ECM to insert your proper VIN number to unlock it.
