Hey guys, this question is actually on my Dad's focus and not mine. He has an 01 with the spi engine and IB5 manual transmission. 5th gear just dropped out on his transmission. When I am looking up junkyard listings...it is listing three different model numbers for the IB5 from that year. Do you know if any IB5 will drop in, or do I have to match up the specific transmission code? The reason I ask is I found an IB5 for $100 which has a different transmission code than his...but it looks the same. Thanks!
