Title: 1979 Chevy C-10 transmission tail shaft leak
Post by: genev on April 07, 2014, 03:36:07 pm

Working on 1979 Chevy C-10, the transmission is dripping at the driveshaft yoke, I have replaced the rear seal, no fluid at the seal, just the drive shaft, how do you repair this.

     Welcome to the site, but we need more info.  What transmission do you have ?  Auto or manual ?
