Tranny Q on '02 325cic Ok, so my parents went and bought an '02 325cic A/T. Long story short, they brought it home and it was noticed that there is a heavy thud/clunk in the trans when it shifts on it's own from 2nd to 1st. If it's in sport mode, whether we are shifting or not, it doesn't happen.
I'm leaning toward a shift solenoid or TCU mapping issue.
Anyone else experience this or have any info to share?
Thanks in advance, Joe |
