M/T - Hops Out of 5TH Gear
NO.: 91-T-33
DATE:
September, 1991
GROUP:
Transaxle
CORP. NO.: 187203R
SUBJECT:
Transaxle Hops out of 5th Gear (Replace Shift Control Housing, 5th/Reverse Fork Retainers and/or 5th/Reverse Synchronizer) All
1991 Saturns with MP2/MP3 Manual Transaxles
CONDITION:
With the manual transaxle in 5th gear, the transaxle may occasionally hop out of gear.
CAUSE:
This condition is caused by the 5th gear synchronizer sleeve lock notches not fully engaging the 5th drive gear clutching teeth due to:
^
The shift control housing does not provide adequate shift fork movement.
^
The 5th gear synchronizer sleeve with scalloped lock notches require more fork travel than a sleeve with square notches.
^
The 5th/Reverse fork retainer (when used with the current shift shaft, P/N 21001086) reduces fork movement.
