TRANSMISSION TROUBLESHOOTING

Check the following items when shifting difficulty is

encountered.

• Engine idle speed is above specification

• Transmission fluid type/quality

• Loose or worn snap linkage bushings

• Worn linkage rod pivot end at the transmission

• Bent bellcrank

• Worn, broken or damaged internal transmission

• Drive clutch one-way bearing

• Worn drive belt

• Clutch alignment

To determine if shifting difficulty is caused by an internal

transmission problem, isolate the transmission by

disconnecting linkage rod from transmission bellcrank.

Manually select each gear range at the transmission

bellcrank and test ride vehicle. If it functions properly,

the problem is outside the transmission.

If transmission problem remains, disassemble

transmission and inspect all gear dogs for wear

(rounding), or damage. Inspect all bearings, circlips,

thrust washers and shafts for wear.
