ISSUE:
Some vehicles may exhibit a "buzzing" and/or "grinding" noise or a "notchy" feeling during the 2-3 upshift. This may be caused by the 3-4 synchronizer.
ACTION:
Replace the 3-4 synchronizer assembly. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
First, verify that vehicle exhibits a buzzing/grinding/notchy feeling/sensation during 2-3 upshift and determine if your transmission serial number is greater than the serial number listed below. If the vehicle does NOT exhibit a buzzing/grinding/notchy feeling/sensation and is greater than the serial number listed on the chart below, proceed with other appropriate diagnostics for repair. Reference the appropriate Workshop Manual for assistance.
NOTE: ALL TRANSMISSIONS WITH SERIAL NUMBERS GREATER THAN THE ONES LISTED BELOW ARE NOT AFFECTED. USE THE CHART BELOW AND THE SAMPLE TAG INFORMATION TO ASSIST IN DETERMINING IF THIS FIX IS APPLICABLE. THE TRANSMISSION SERIAL NUMBER IS LOCATED ON THE TAG ATTACHED TO THE LEFT SIDE OF THE TRANSMISSION.

Drain all fluid from the transmission and remove the transmission following the procedure outlined in the appropriate Workshop Manual.
Disassemble the transmission following the procedure outlined in the appropriate Workshop Manual.
Inspect the brass blocking rings for any damage. If they are not damaged, reuse on reassembly.
Replace the synchronizer. Additionally, replace brass blocking rings if necessary.
Reassemble the transmission following the procedure outlined in the appropriate Workshop Manual.
Reinstall the transmission and fill with new fluid. Test drive to verify repair.
NOTE: AFTER THE REPAIR, THE TRANSMISSION MAY FEEL STIFF, ESPECIALLY IF THE BRASS BLOCKING RINGS WERE REPLACED. THIS WILL GO AWAY AFTER DRIVING THE VEHICLE FOR SEVERAL KILOMETERS/MILES, AS THE NEW BLOCKING RINGS NEED TIME TO RESEAT AGAINST THE GEAR CONE.
