Good morning, Rick and Easternmost Winnebago; 

     Rick, you are right. 

     It did not rain last night, so I slid under the Winnebago Elandan this morning with the caliper in hand and checked the outside diameter (OD) of the ATF oil cooler lines on the 3L80 or THM-475b transmission, and they are indeed 5/16 inch OD.  It is the fuel line going from the gas tank to the carburettor that is 1/2 inch OD.  At least the origin of my confusion over the tubing size has been identified.

     While I was looking at the 1/2 inch fuel line, I did notice that one of the connecting rubber hose pieces going from the fuel line to the in-line fuel filter is developing a longitudinal crack in the outer surface.  I need to go get some fuel tolerant 1/2 inch ID rubber hose to use for a replacement for that fuel filter connection.  Maybe I will also replace the fuel filter while I am there.

          Enjoy; 

          Ralph

Well I tried to order a Transmission dipstick top seal but ended up with the tube grommet with the right built in lips to seal the dipstick tube itself at the trans. but nothing available at Summit racing where i get a discount. I Even googled it under trans. dipstick seal, grommet, cap seal, wiper seal, you name it but no replacement seal like that or even any pictures of it can be found, but plenty of companies selling the complete dipstick , assembly. Any ideas? am i using the wrong terminology/name ?

That seal is part of the dipstick. Can't help with finding one though.

Well i suppose it's time to visit the junk yard. I'll take my dipstick and see if i can find a newer locking type transmission stick with the same diameter tube as mine and the right length then if i need to i'll remark the full level on the new stick if it doesn't measure the same from the bottom/top of the stick.

I Found one this afternoon on a Wrecked box truck with a Chevy Motor. Now i need to replace the valve cover gaskets. Someone in the past reworked the passenger side head but didn't tighten down the valve cover bolts and the gasket swelled uneven and let oil leak down on the manifold making it smoke like hell, i just got some parts from UPS A few minutes ago. Now i can go to work finally.
