What do they come in? I thought you had to get a 904 or 727 to get a non-lockup.
 
Not all of them have a five disc drum. I happen to have a nice five disc drum that's a reman unit with new clutches that I am not going to use if you are interested.
 
My 998 came out of a 76 Cordoba 360. Has an extra clutch pack. Also, its a nice upgrade with the part throttle kickdown.
 
Mitchell interchange manuals, Hollander interchange manuls, and the Hollander E-book.
 
That's because they are all 904s. They are all based off the 904. The 904 simply grew and changed as requirements grew and changed. Just like the A500 is a 904, simpy with an overdrive unit made into it.
 
I was dealing with this awhile back and found out the only way to tell
a 998 from a 999 is to tear it down and see number of clutches 4=998
5=999 and mine is a 1984 so earlier may be different ????????????????

I think you made my point. I thought the number change.....500, 999, 998.... indicated a change to the standard 904 and that the change was that it used a lockup converter and/or had an overdrive. Is that not true?

The 998 and 999 were both available in lockup and non lockup versions.
 
Do you know the application? All the 318 applications I looked up showed it having a lock-up converter. The only 360's without a lock-up I see say the trans is a 904 or 727.
 
No I do not. But I have had several of each in the past. The 5th Avenues through the 80s would have had the 999 because of the need for the low gearset.
 
The earlier 904LU were a hydraulically controlled Lockup system and the late 904LU used an electrically controlled system.Still hydraulics but electrically activated.
The late 904LU you'll be able to use a toggle switch to activate LU if you desire.
Nice option to turn it on or off when your burning the tires.
 
I have a A999 in my shop. It has the Low gear set in it also along with the 5 clutches mentioned earlier.
I am in California so it would not be beneficial when it comes to shipping.
 
From an earlier post looking for the same thing...

'74-'75 3681844
'76-'77 4028465
'78 4028878

I would have guessed they were 1 year only ('76), but the claim is they were available as early as '74 and late as '78 with the P/N's... Maybe someone can look that up...

I agree, I've pulled a bunch from those cars, but every one I pulled had a lock-up converter.

Thanks for checking, I wonder where they got those numbers from?

I spent some time doing a lot of Chrysler/Dodge R&R's in the 80's and had never ran across a Non-Lock up A998/A999 although we did replace some with A904's in a few trucks and one van at the customer requests for cost reasons...

Could they be a High Altitude/49 State oddity, or remain elusive like Sasquatch?
