Primary fluid change

Reading the threads and posts on the forum re: amount of fluid for a Primary change is akin to sometimes getting a real headache. There are stories and anecdotes that make me want to just shake my head in wonder. ![Wink](https://www.hdforums.com/forum/images/smilies/wink.gif)
If the factory manual for my 2011 RKC says 38oz on a wet change, then that's why I put in 38oz on Saturday when I did a three hole oil change.
Maybe someone could 'illuminate me' but why on heaven's name are people putting in all different measurements of fluid in their primaries? Am I missing something here?
Sure, for an earlier model/engine, the manual calls for 32oz. That's cool!
But for a later model that calls for 38oz...
I subscribe to the KISS principle! I do not like to second guess myself especially when I supposedly 'follow' factory directions.
However, when I read that people are putting in MORE (or less) than the factory recommended wet change amount... WTF?
YMMV...

thats for a 'dry' primary. ie. if you've had the whole cover off. if you're just doing a change, its a 'wet' spec = 38oz

Just went thru my primary checking everything. Here's how I check it. I have a white twist tie for a plastic bag. I make an L shape bend in it. I determine the distance by eyeballing the spring retainer on the top side to the edge of the spring. If you look down at bottom you will notice the the retainer actually goes about 1/4 inch or so below opening in primary cover. Need to add that amount to the length. Then I drop it in to the bottom edge of the opening. Mine only needs 26 oz or so even when I have had chain and clutch completely out. Thing my dip stick was about 1". I know for a fact that after the 26-32 oz, another quart will go it before it runs over edge. Let some one else add the oil why we were talking and only noticed it when I did not have the oil for the transmission. My service manual says 26 for my 04 TCb 88. You cannot see 4 oz more distance in there even with a dip stick.
