Leaking Driveshaft...HELP!!!
That is for a gm trans and it NEEDS to be there.
Your plug is probably the issue and is seeping fluid, the welch plug is pressed in and makes a tight seal to keep fluid in and seal, when the slip is splined it's drawn thru and then the plug is added.
You can either visit your local driveline shop and have a new one installed in the slip or you can clean it good and put silicone on the plug
