...Goes Unpunished!

A few weeks ago I swapped out the transmission fluid for the magic elixir ACDelco Friction Modified stuff.  And it seems the transmission is shifting more smoothly.  I guess that stuff is really slippery as I've now developed a fluid leak at the speedometer cable right where the black housing is fitted into the pressed collar.  I guess a new speedometer cable is called for, right?  Is it normal for this connection to have transmission fluid present or is there some other seal I should also be replacing?

Thanks,

Jim

I'm betting your answer will be in here: https://www.google.com/search?q=speedometer+cable+seal+site%3Aclassiczcars.com&ie=utf-8&oe=utf-8

From last month:

 

I replaced that dime sized oil seal in mine about a month ago. Not one drop so far. A few dollars from Nissan. 

that's the thread with the info Steve posted above. I had to go back and read through it.  Steve is the Man!

Boy, when it rains it pours. Seems like everybody's crapped out around the same time.

Steve and Cliff - thanks for the help.  I'll get into the pinion gear today.

Jim

I used a deep socket to press mine down. They have to fit down on a ridge in the pinion gear housing. Something you may have to do to get all the old one out is to use a needle type pick and scrape inside that ridge. I had to find my cheapo magnifying glass to see down in there.

All done, Cliff's newspaper leak check is in progress.  Courtesy (10 min. from my house) had the parts in stock.  Check out the list price on that shaft seal .  The young parts desk guy was funny - "Uh oh, my system doesn't go that far back."  Me: "That's why you need David or Butch."  Parts guy: "Yeah, let me get this info to Butch in the back".  Heaven help us all if Butch and David don't train these new guys on how to look up parts in the old catalog.

Cliff - your extract and install tips were spot on!  My machinist's scribe has a right-angle point and was perfect for pulling out the old seal.  A long 11mm socket was the perfect install tool.  A bit of anti-seize allowed everything to slip right into place.

Thanks again to you both for great assistance.

Yep....My 280ZX 5 speed speedo cog gear in the 73 is leaking too. Just received the two seals from Motorsports......appreciate all the info

It makes my day when I receive that sort of compliment, I actually provided pertinent information. 

Thank you Jim, we can have fun here in the States next week during ZCON.

Also a big THANK YOU to @Chickenman, he's the one that popped out the part number right off the bat.

Just replaced the seal and O ring in the speedo gear. No leak so far. BTW.....that little inside seal has a direction to be installed. If you look closely, the lips of the inner seal need to be facing into the transmission.....just like any other seal.

What results do you guys have?  No leaks I hope.

Jim A. most of my 240 parts come from Irving, TX.  I know that's a distribution center, is that how Courtesy keeps their inventory so straight?  Is Richardson close to Irving? 

........not a drop!
