jeep tranny retrofits (1987 & newer)
If the overall length is not a concern or you’re looking for the easiest adaptation, we also offer a complete line of adapter plates for
these transmissions. The adapters are all based around the Dodge transmission and the length of the Dodge input shaft. The
Dodge transmission input shaft has a stickout length of 7-1/2”. This allows us to use an adapter plate and then couple it to the stock
AMC bellhousing.

NV3550 or AX15 Replacing the PEUGEOT: This transmission assembly is for Jeeps previously equipped with
a Peugeot 5-speed transmission. The Peugeot 5 speed transmission is considered a light-duty transmission. When
retaining the stock 6 cylinder, the NV3550 and AX15 transmissions are exactly the same length as the Peugeot. They
can be installed in Jeep Wranglers without driveline modifications. This assembly fits Jeeps from
the years 1987-1989, with the New Process 231 or 207 transfer case. The overall length of the new
transmission will be within 1/4" of the original Peugeot tranny. This kit comes with a new
23 spline New Process input gear for your transfer case. The transfer case must be taken
apart to install this new input gear. These kits include a new transmission, bellhousing,
crossmember adapter, transfer case shifter bracket, slave cylinder kit, transfer case
input gear, and a transmission shifter handle.

AX15 Replacment: On Jeeps that have the AX15 with an internal hydraulic release bearing, you will be required to purchase
our bellhousing and slave cylinder kit listed below. You can also swap your front bearing retainer from the internal release AX15
transmission to our new Ax15 transmission and bypass the purchase of this bellhousing.
P/N 26-AX15 - New AX15 transmission
P/N 712590 - Jeep 4.0L bellhousing to AX15(for replacing the AX15 internal hydraulic)
P/N 716340 - Jeep slave cylinder kit for 712590 bellhousing (replacing AX15 internal hydraulic)
NP435 to JEEP 4 cylinder replacing the AX5: The NP435 is a excellent transmission choice when retaining the stock 4
cylinder engine. You do lose the overdrive 5th gear, however; you do get a much lower first gear along with a stronger transmission.
The NP435 must be equipped with a 7.5” input shaft to work with this adapter. The most common NP435 shaft is only 6.5” long.
This kit also does require some machining to the stock NP435 front retainer. The kit comes with a adapter plate, pilot bushing,
hardware and the machining requirements for the NP435 requirements. This kit couples to the stock AMC bellhousing and can
be used with both an internal or external slave cylinder.
