Fix Trans Fluid Leak Through Wiring Harness Connector using Sonnax Bracket and RTV
The poor design from GM for the 4L60E 4L65E 4L70E relies on an O-ring, double sided seal and several retainer clips (which break or wear) in order to be leak free. This video shows the easy way to fix it on the cheap. GM no longer offers the O-ring or double sided seal so you have to resort to aftermarket or the junk yard. Fear not: MR DIYGUY123 is here!!!
