T19 Ford Truck 4SP: This transmission looks identical to the Ford T18, and the case length is the same. The 1st gear ratio
is 5.11:1 1st; 2nd 3.03:1; 3rd 1.79:1, and 1:1 4th gear ratio. These transmissions were used in Ford pickups 1974-88. The first gear
on this transmission is synchronized, which is the biggest advantage over the T18. The adapter kits we manufacture for this
transmission requires a new main shaft. This shaft looks identical to the Ford T18, except it has a snap ring groove for the 1st gear
synchronizer. This kit includes a new T19 main shaft and a new 3.25” thick adapter housing that couples the transmission to the
Dana 300 transfer case.
Ford T19 to Dana 300 Optional Items:

NP435 Ford Truck 4SP: We manufacture many adapters for the Ford version of the
NP435. These adapters do not work on the Chevy or Dodge NP435. This transmission
has a case length of 10.875”. The 1st gear ratio is 6.69:1; 2nd 3.34:1; 3rd 1.66:1, and a
1:1 4th gear ratio. This transmission was used in Ford pickups 1969 to 1979. It is easily
identified by an aluminum shift cover. This transmission is available
with two front input shaft lengths. The 6-1/2” input shaft stickout length
is the ideal version to look for. This kit is 4.25” long and has a new main
shaft that must be installed into the transmission. This kit is supplied
with the proper gaskets and bolting hardware.

GM NV4500 (1993-94): During the first two years of the NV4500,
Chevy offered this 5 speed with a 6.34:1 1st gear; 2nd 3.44:1; 3rd
1.71:1; 4th 1:1 ratio, and a 27% overdrive. It was also the first year
that Chevy changed the bellhousing-to-transmission bolt pattern. This transmission is ideal when
converting your vehicle, providing an ultra-low 1st gear. GM, however, only produced this particular
ratio during these years. The major complaint of this 5 speed was stiff shifting and noise in 3rd gear.
(1995): This transmission is identical to the 1993-94 transmission, except the 1st gear ratio had been
changed to 5.61:1; 2nd 3.04:1; 3rd 1.67:1; 4th 1:1 ratio, and a 27% overdrive. The noise and shifting
problems had been corrected. (1996-2005): This transmission has the same gear ratio as the 1995
version. Chevy once again changed the bellhousing-to-transmission bolt pattern and went to a larger bellhousing index diameter.
This Chevy NV4500 has the same bellhousing-to-transmission bolt pattern as the Dodge NV4500. These transmissions use a
GM internal release bearing. All the NV4500 transmissions have a 12.375” case length. This kit includes a new adapter housing
that houses the 5th gear assembly. We use a new shaft for this transmission to couple to the 6 spline gear of the Dana 300 transfer
case. The spud shaft will only fit the GM NV4500 output shaft. The stock output shaft must be cut to a specific length to work in this
kit. Some transfer cases require the stock linkage to be modified for clearance on the NV4500 case.

We offer complete packages for this transmission. 716048 Trans mount
Dodge NV4500 23 SPL.(1993-1998): This transmission is the same as the 1996-99 Chevy version; however, the only
differences are the transmission input shaft lengths (Dodge 7.5” & Chevy 6.5”), output shaft splines (Dodge 23 & Chevy 32), and
the tailhousing lengths and bolt patterns. Dodge NV4500 29 SPL.(1999-2005): For the transmissions in these years, Dodge
changed the shifter stud on the top cover to a threaded stud, requiring a different shifter handle. In 2001, Dodge changed the output
spline of their transmission to a 29 spline. We stock this 29 spline transmission under P/N 26-0029. All NV4500 transmissions
have a 12.375” case length.

ZF Transmissions: The ZF 5 speed has been used in full size Fords from 1987 to the current models. These transmissions
are now starting to show up in salvage yards, and we’ve been getting more requests for adapters to couple this 5 speed to the various
transfer cases. We now offer a kit that couples the ZF transmission to the Jeep Dana 300. This aluminum adapter is .750” long
and comes with a new Dana 300 input shaft. The ZF 5 speed is a large transmission and, due to its size, driveline modifications
and a body lift are required. This transmission has either a 4.65:1 or 5.72:1 first gear, and a 23% overdrive which makes it an ideal
transmission for on and off road capabilities.
