MANUAL TRANSAXLE DIAGNOSIS

INTRODUCTION

M1221006900615

The manual transaxle can exhibit any of the following
symptoms: noise or vibration is generated, oil leaks,
shifting gears is hard or troublesome, or the
transaxle jumps out of gear.

The causes of these symptoms could come from:
incorrect mounting, the oil level may be low, or a
component of the transaxle may be faulty.
