There is overlap between the life of Borg-Warners heavy duty four
speeds, but basically the T-19 followed the T-18. The T-19 was the
first one to offer a synchronized first gear. Typically, this meant
that first gear wasn't as low. The exception to this rule was the rare
wide ratio T-19 used in IH trucks. Wide a close ratio versions of the
T-19 were used in IH trucks, so most T-19s in IH trucks are not the
wide ratio version. The T-19 was also used in Ford trucks.
The input bearing retainer size (4.85") and often the input shaft
length is compatible with the bell housing used with the T-150, T-176,
T-5, T-4, SR-4 and of course Jeep T-18. The input shaft length varies
depending on the application, but the shaft can be cut and resplined
or an input shaft of the appropriate length can be installed. If this
transmission is to be used with a Jeep Dana 300, it is easiest and
cheapest to buy a 2WD Ford version. The 4WD IH version should be bolt
compatible with a Dana 20 or Dana 18, but input shafts are typically
on the long side.
Generally, Wranglers, Cherokees, etc. with the
NP-231 or
NP-207 transfer case will be best of converting a 2WD Ford T-19. A
special bell housing can be purchased or a CJ bell housing can be used
(some modifications may be necessary.) It might be best to take the
opportunity to upgrade transfer cases for Wranglers with the NP-207.
CJs with the
Dana 300 are also generally best off converting the 2WD Ford T-19.
Often, the stock bell housing can be used or modified to work with the
Ford T-19.
For CJs with the
Dana 20, it really depends on on what can be found at what price.
The Scout T-19 may be the best option, but it is hard to find. It
might be better to convert a Ford T-19 and swap in a Dana 300 to get a
better low range.
Things get much more complicated for people with a
Dana 18 Finding bell housings that are compatible with the T-19
for engines used 1971 and earlier can be extremely difficult. A
special bell housing may have to be purchased. If you have a Buick 225
V6 or are planning a Chevy engine swap, most likely it would be better
to go with a Chevy transmissions.
The ultimate low buck, junk yard, bolt in swap is the Scout T-19
and
Scout Dana 300. Problem is the wide ratio Scout T-19 is very rare
and the Scout Dana 300 almost as rare. It isn't likely someone is
going to sell you these parts cheap if they know what they are.
