  1. OEM Issues
    So i started to remove my 4l60e from my envoy as i had (what i thought was just 1st but is really 3rd) and reverse to get it rebuilt. But after more research i went to check voltage at the plug and the meter would spike up to ~7.3 volts for a few seconds and then shoot back down to zero. Ive...
