Specifications

Dodge NV4500 (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. The adapters to couple the Dodge NV4500 to the New Process transfer case utilizes the stock transmission
output shafts. The kits consist of a new adapter housing, transfer case linkage and necessary hardware. When using a new 29
spline transmission, you will also be required to purchase a new 29 spline input gear for your transfer case which is listed below.

Jeep NV3550 Transmissions: This 5 speed is rated at 300 ft./lbs. at 7200 GVW. The weight of this 5 speed is 97 lbs. The gearing
of this 5 speed is as follows: 1st 4.01:1; 2nd 2.32:1; 3rd 1.40:1; 4th 1.00:1; 5th 0.78:1, and Reverse 3.57:1. The NV3550 transmission
is ideal for retrofitting the Peugeot 5 speed. The NV3550 transmission is within a 1/4” length of the Peugeot 5 speed, making this
an ideal swap. The transmission shifter towers are within 1” of each other, so floorboard modifications are very minimal. Even though
the length of these transmissions are the same, the transfer case splines are different; therefore, we provide a new input gear for
either the New Process 231 or 207 transfer case. The only available rotation for the New Process transfer case to the NV3550 is
the 13 degree rotation. This could cause some floorboard interference on vehicles that originally had a 23 degree stock rotation.
The transmission kits we offer include a new NV3550 (P/N 26-3550R), a full bellhousing (P/N 712590), a transfer case shifter linkage
(P/N 715545), a crossmember adapter mount that retains the stock Peugeot rubber mount (P/N 716007), a slave cylinder kit (P/N
716340), and an input gear for your transfer case (P/N 716053 NP231 or 716096 NP207). These components can be ordered in
one of the two kits listed below:
27-3507R NV3550 to Peugeot 5 speed replacement with NP207 transfer case
27-3510R NV3550 to Peugeot 5 speed replacement with NP231 transfer case
Jeep AX15 Transmissions: The AX15 transmission has always been a great transmission able to handle the torque and
horsepower of most V8s. The biggest problem now is the availability of new units. With the lack of availability of new NV3550s,
we revisited the possibly of obtaining the Asian Warner AX15 transmission and were successful. Although the torque
specifications are not listed on this transmission in any service manual, we feel it‘s similar enough to the NV3550. The NV3550
was the transmission that superseded the AX15; and Jeep used the same engine with the same vehicle ratings. With the availability
of AX15 transmissions, we can now offer some additional transmission retrofit applications. P/N 26-AX15
AX15 Direct Replacement: The AX15 was use between 1988 to 1999 in the Jeep vehicles. Since these Jeeps are getting up
in mileage, a new AX15 makes sense as a direct retrofit. Available in both an internal and external release bearing design.
AX15 retrofitting the AX5: This is a newer kit for all 4 cylinder Jeeps 1987 to 2002. The AX5 is considered a light duty
transmission compared to the AX15. Jeeps equipped with larger tires and lower gears in the axle & transfer case may find
the weak link in the drivetrain is the stock transmission. You can now install the AX15 in place of the AX5 to gain some drivetrain
strength. The nice thing is that when you’re ready to replace the 4 cylinder with a larger V6 or V8, the AX15 is an ideal
transmission for the power increase.
Peugeot 5 speed Replacement: The AX15 is the exact same length. The kits we offer include a new input gear for either the
New Process 231 or 207 transfer case. Due to vehicle variances, some applications may require transfer case linkage
modifications. Kits include a new bellhousing, transfer case shifter linkage, a crossmember adapter mount to retain the stock
Peugeot rubber mount, slave cylinder kit, and an input gear for your transfer case.
AUTOMATIC TRANSMISSIONS:
We now offer rebuilt automatic transmissions with our adapter kits installed. To stand up to the stress & strain put
on most 4WD vehicles, these transmissions are built with the best heavy-duty components available. We offer most
makes and models for GM, Ford, and Jeep vehicles. These transmissions are all dyno tested and come with a 2 year
or 24,000 mile warranty. Call for applications and pricing.
TH350: This GM automatic was commonly found stock in vehicles from 1969 to 1981. It was used in both the 4WD pickups and
2WD car applications. These transmissions are identical except when it comes to the output shaft stickout length. The 4WD
transmission used an adapter to bolt this transmission to its stock transfer case. With this adapter removed, the stock output shaft
protrudes from the back of the transmission case approximately 1”. On 2WD vehicles, these transmissions used 3 different
tailhousings. The lengths of these tailhousings are 6”, 9”, and 12”. The output shafts lengths correspond with these tailhousing
lengths. This transmission is one of the most popular choices for engine and transmission conversions due to the overall length
of 21-1/2”. The 1st gear ratio is 2.52:1; 2nd 1.52:1, and a 3rd gear ratio of 1:1. When converting with this transmission, we recommend
that you cut the two tabs as illustrated. This allows for exhaust and firewall clearance. We offer several adapter options for the TH350
transmission.
