[ihc] RE: Manual Transmission Differences T-18 & T-19 for Various Engines & Transfer Cases

["Peter Shubin" <pshubin@xxxxxxxxxxxxx>]

Good information as always.  I have a picture of my T-18 looking into the
bell housing when I had the engine out.  Is there someone that can compare
it to a T-19 that they have or will recognize the bell housing to
transmission bolt pattern?  I would be glad to send it over.

If I had both set ups (T-18/Dana 20 and T-19/Single Speed) could I use the
bull gear from my T-18/Dana 20 on a T-19/Dana 20?

I think I also need to be clearer about what I am thinking of doing.  I
currently have a '72 Scout II running an AMC 360 with the original drive
train.  The Scout originally came with a 258 that I swapped out a few years
ago.

In searching for the parts for my next project on the Scout I ran across a
192/T-19/Single speed transfer case setup.  If the T-19 is a wide ratio unit
I want to swap out my T-18 for the T-19 and keep the rest of my drive train.


Everything except the clutch works fine.  Since I need to drop the
transmission to replace the clutch with one with more holding power I
thought it would be a good time to do the transmission swap too if it would
all bolt together.

I am playing with all Scout II parts except for the 360.  The 360 should not
make a difference because the changes I had to make to get it in the Scout
had nothing to do with the drive train.

My understanding has always been that an IH T-19 was an IH T-19 was an
IH T-19 as far as the front end was concerned.  That when a 258 was to
go in, they just used a bellhousing set up for an AMC rather than the
one for an SV.  I have a T-19 that came out of a 258 equipped truck (150
or 100) that I parted out.  I unfortunately I don't have a loose T-19
from behind an SV or 196 to compare to.  Somebody give me some
measurements and I will check the front end out. 

My impression of what Pete needs to do on the front end of the tranny is
drill the other two holes out of the T-18 bellhousing to mate it to the
T-19.  There are two holes above and 4 holes below the hole in the
center.  I believe they are in a straight line up and down on either
side. The top ones are the same for T-18 and T-19.  The next ones down,
roughly making a square with the top two are for a T-18.  Below them,
making a rectangle with the top two, are two bosses where the holes need
to be for a T-19.  Input shafts are the same in every way no matter AMC
or SV.  Drill out the bosses and bolt it up.  

Maybe I have believed wrong for years.  I will compare the T-19 with a
T-98s I have around. The only other T-19 I have is still between a Dana
20 and a 196.  

Someone else will have to help with the back end and the connection with
the T-case.  I've never messed with a single speed.

Peter, I had looked at doing this once upon a time.  The answer is yes
and no.  AMC used several input shafts on the same application T-18,
according the transmission parts suppliers I talked with.  In an effort
to use as much existing inventory on new cars and trucks, they used
several different adaptors along with several different bellhousingsn
depending on what was on the shelf, so it may work, depending on whether
you get lucky and get the correct length input shaft along with the
correct depth bellhousing (there were 4 that AMC used) along with the
correct bellhousing adaptor (mounts between the bellhousing and the
transmission).  Do not just go out and get the first transmission you
find, or the first bellhousing you find, because chances are it will not
work unless you did the proper measurements and comparisons.  If you
have a T-19 already, then maybe you could find a Jeep transmission that
still has the bellhousing and adaptor with it, and measure the length of
the input shaft to see if it is the same, in which case that bellhousing
may fit.  Of course you still have to make sure the crank pilot does not
stick back further than the engine the transmission came from, else you
may bottom out the Jeep input before it is tightened down to the block.

Your post was kind of confusing:  are you talking about putting an AMC
360 in a Scout using an IHC T-19?  What exactly is it you are proposing?
