SUBJECT:
NSG370 6-Spd Transmission - May Not Remain In Reverse Gear When Selected
OVERVIEW:
This bulletin involves replacing both the internal shift subassembly and the mainshaft reverse gear components.
MODELS:

Liberty / Cherokee

Wrangler
NOTE:
This bulletin applies to vehicles equipped with a NSG-370 6-speed manual transmission (sales code DEH).
SYMPTOM/CONDITION:
Upon shifting the 6-speed manual transmission into Reverse, the customer may notice that reverse gear may not remain engaged.
This condition may follow/develop shortly after an accidental mis-shift into reverse has occurred. While the vehicle is moving forward and already in a
forward gear, instead of shifting into another forward gear the reverse gear is incorrectly selected. Though reverse can not be obtained during the
mis-shift attempt, damage to the internal shift subassembly and reverse gear may occur which may later prevent full reverse gear engagement when
reverse is selected properly. The customer should be made aware of proper shift procedures.
This condition may also occur if the center floor console and/or shifter boot are not positioned properly.
DIAGNOSIS:
1.
Verify that the center floor console and shifter boot are not preventing the transmission shifter from fully engaging reverse. Verify that the console
is centered properly to the shifter. Verify that the shifter boot is installed properly.
2.
If the center console and shifter boot are properly installed, and the transmission fails to remain in reverse as designed, perform the Repair
Procedure.
