SHIFTABILITY CONCERNS ON ISUZU 5-SPEED MANUAL TRANSAXLE
Model and Year:
1983-90 J CAR
TO:
ALL CHEVROLET DEALERS
Owners of some 1983-90 J-cars equipped with Isuzu 5-speed manual transaxles (RPO MK7, MR3, and MY7) may comment about one or more of the
following:
1.
Transaxle hopping out of gear.
2.
Higher than normal shift efforts.
3.
Shifter rattle or buzz.
These conditions may be more apparent during cold weather operation.
Any of these conditions may be the result of the shift boot being too stiff.
FIGURE 1
To repair any of the above conditions a new shifter boot should be installed (P/N 22553175). The new shift boot is made of a more pliable material.
If the new boot does not satisfactorily fix the customer concern, consult previous bulletins on these subjects.
The new boot will only back service vehicles which are equipped with a boot identical to the one shown in Figure 1.
