Can you explain the 7 Series also?


-------------------------------------------------------

Chrysler brought out their 7 series transmissions
which are direct decendents of the 1957 HEMI
Wing cars - which had cast Iron cases .

The A-727 TorqueFlite comes in Three Build Configurations
and has a few upgrades available since these Trannies are
capable of handling 1,000HP in Blown Hemi Form - once
built correctly .

Unlike the 9 series - the 727 Identity is carried on all
Transmissions - only stamped numbers will tell what
the internals are about .

The 727 came in Three Build Varients - as did the 9 series.

Stage one is a light duty unit - 3 clutches / 3 steels etc.

Stage two is the 4 clutch / 4 steel HD transmission that
is used on Street Vehicles & HD applications such as
Motor Homes - . These have the 4 pinion planatary -
larger clutch basket / larger drum / wider bands etc.

Stage three is the HEMI TorqueFlite - with 5 clutches / 5 steels
large drum / large clutch basket / large kickdown lever / 4 pinion
planatary - . The HEMI Torqueflite for 1969 is different from the
1970 and different again for the HEMI TorqueFlite of 1971 .

Changes in the valvebody is most of the difference .



As far as AMC car applications - AMC used the 3 clutch / 3 steel
units .

The Units in the Wagoneers carried 4 clutches / 4 steels.

You can add clutches and steels when you rebuild -
by ordering them in a kit .

Anyone needing rebuild parts suppliers - I have two -
one which supplies most all the others for parts .

For the 5 clutch trans. - you'll need the clutch basket 
etc. since it is more of everyting .

Anything over 5K RPM - on a Stock 5 clutch Torqueflite
will roast #5 clutch - as there is no oiling provision for it.

Some . Builders know this and do mods to protect that
clutch plate .

There are a number of kickdown levers available - 
each with their own operating advisements.





Subject: 9 Series TorqueCommands : 904 / 998 / 999

Chrysler has / had Two Series in their Transmissions :

the 9 series 
the 7 series

Within each series - they had three builds :

In the 9 series - this would be :

904 / 998 / 999 ,

904 is for the Economy 6 engines 
and contains 3 clutches / 3 steel plates -
and narrow band - smaller drum etc.

998 is for Mid power engines - Torque motors -
like the 304 / I - 6 4x4 AMC products .
It contains a wider band - larger drum - 4 clutches /
4 steels etc . Has webbing cast onto the top
of the Trans. Case - can't miss it.

999 has been used behind the MoPar 
Duster 360 and Wrangler JEEPs up
thru the year 2000 .
It contains 5 clutches / 5 steel plates / widest band
big drum , 4 pinion planatary etc. and also
has webbing cast into the top of the case .

If you have a pencil size hole in the center
of the Input Shaft - you have a Lock Up
Convertor Trans. starting roughly around
1979 for Chrysler Products and 1981 for
AMC .

My 1981 Eagle Series 50 has a Six
and a 998 Lock Up Convertor Trans.



The 904 is a SIX cyl. Trans. non-4wd Vehicles

The 998 Came behind the 304 and the EAGLE 6.

You can tell a 998 Trans. as there is EXTRA BRACING
on the back ( or TOP depending if the car is on a lift or not )
of the Trans. Case . The Bracing is cast into the case -
and is clearly visable . 904 Trannies do not have the
Extra bracing .

You have an Original 304 V8 Gremlin "?" - 
You have an Original A-998 TorqueCommand.
