| The 5 speed transmissions used in Wranglers 87-88 is
generally considered an inferior unit. If you have one, and it is
tired, a Conversion to the NV3550 might be just what the doctor
ordered.
It is also possible to replace the Peugeot with an AX 15 (The 5
speed Jeeps used 89-99). However the NV3550 is generally
considered to be substantially superior to the AX15.
We can supply the NV3550. We have also put together a package of
the key items needed to make this upgrade. This install kit
contains a new bellhousing, a bracket to retain your stock Tcase
linkage, A crossmember adapter plate to bolt the new trans in using
stock components, and a clutch slave cylinder and hose kit designed to
work with your stock master cyl.

Transfer Case
If you are retaining the original Tcase, a 23
spline input gear will be supplied. It is a matter of removing the
bolts that separate the case halves, The two sections will come apart.
The planetary assembly is removed from the front section (a snap ring
holds it in). Replacing the input gear in the planetary assembly
involves removing another snap ring, taking out a thrust plate and
thrust washer. The sun gear can then be pulled out. If you took it
apart and laid the parts out in the order they came out, it is a
simple matter to re-assemble the unit by putting the parts back
together in the reverse order they came out. No special tools are
required except perhaps snap ring pliers.
Other options include an Atlas
Transfer Case, A
Klune-V
Extreme Underdrive (with the Stock Tcase), or the “Hercules”
Klune/Bronco Dana 20 system for Jeeps, or other variations.
Clutch
Your stock clutch components will work, however should be replaced
if not known to be fresh. We can also supply these parts as a part of
your package (Package pricing tends to be better than prices for items
purchased separately)
Driveshafts
As the NV3550 is the same length as the Peugeot it s replacing,
driveshaft modification is not necessary.
Deeper Gearing Options:
NV4500 Conversion
There is one other popular replacement option for
the AX5: The NV4500. This trans is way-oversize for the
application, and requires a body lift or extensive floor pan
modification to fit. The usual incentive for this conversion is to get
the truck style wide ratio, almost granny 1st gear which
can be useful for offroad use. On the other hand, this conversion will
make a 4 cyl jeep drive more like a dump truck. If this looks like th
eoption or you, High impact does have
available a package using the NV4500
replacing the AX5.
NV3550 / Klune-V Extreme underdrive
Rather than a granny gear 4 or 5 speed, A more
"premium" alternative to achieve extreme gearing would be an
NV3550 combined with a Klune-V
Extreme Underdrive.
