Specifications

T98 Truck 4SP: This transmission, found in 1960 to 1971 Ford pickups & Jeeps, is identified by a case length of 11.875”. The
1st gear ratio is 6.39:1; 2nd 3.09:1; 3rd 1.68:1, and a 1:1 4th gear ratio. The adapters we manufacture for this transmission come
with a new main shaft. This will usually allow the overall length of this transmission to remain ideal for most short wheel based
vehicles. Ford was not the only manufacturer who used the T98 transmission. When searching for a T98 in salvage yards, make
sure the bellhousing bolt pattern has a dimension of approximately 8-1/2” across the top, and 6-1/4” top-to-bottom. The input shaft
stickout should be approximately 6-1/2”. It is easier to adapt to the Ford T98 than to the Jeep or Scout T98 because of the length
of input shaft. These kits are a main shaft style kit. All the adapters include a new 3.25” thick adapter housing that couples the
transmission to the New Process transfer case.

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 adapter housing that couples the transmission to the New Process
transfer case.

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. These kits come with a new housing and 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 is only offered
as a 23 spline option. Transfer cases with a 21 spline input must upgrade to a 23 spline transfer case input. The kit offers a new
23 spline output shaft for the NV4500. This new output shaft must be installed to obtain the right spline for the New Process transfer
case. The kit also includes a new tailhousing adapter and transfer case linkage bracket for the Jeep YJ Wranglers.
