Thread: KR after Transgo shift kit

How old are your plugs? Copper plugs need to be changed every 10-15k depending abuse if I remember correctly.

Plugs have 150 miles on them, I change them every 5000 miles when I change the oil. I put my data logger (brother) in the passenger seat to watch the aeroforce and it turns out the KR only happens when it's shifting, it quickly goes away after the shift.
