The A604 electronic controlled automatic overdrive transaxle has some very unique features. This unit contains no bands or freewheel devices and shifts from clutch to clutch, which requires very precise programming of the onboard transaxle controller. The electronic system is designed to abort the transaxle to second gear if a transaxle problem is detected, however you will still have reverse, park and neutral, which will allow the operator to "Limp" home. Through a variety of different fault codes the technician will be able to diagnos the cause of the malfunction, and repair the concern. This booklet is designed to provide you with the procedures necessary to service, overhaul or repair the A604 transaxle. Note: There have been many engineering changes in this transaxle since its introduction in 1989. ATSG also has available an "Update Handbook" which includes the many changes and is required along with this manual for a proper overhaul or repair.
