[chris3100]

I recently purchased a 99 3400 @ 282 getrag off craigslist for 150 bucks !!! Anyway it included both axles ,shifter & cables ,harness &ecm ! The guy had no idea what he had,and I think I laughed all the way home. ECM # is 88999196. I've looked at the ecm list etc. found notta. Anybody got an idea of what it came from? Maybe remanned 7730?
