MAINTENANCE a LUBRICATION R Common lubricant SAE 80 Multipurpose Gear Lubricant is used in the four speed transmission and differential carrier so no oil seals are used between these units Actually there is some interchange of lubricant as a lubricant dam is formed at the transmission which prevents entrapment of excess lube in the carrier sump which is below the transmission level thus maintaining transmission lubrication on upgrades Oil Level Check Each 1000 miles check the lubricant of the fourspeed Transaxle by removing the filler plug in the differential carrier If oil is at the level of carrier filler plug both the carrier and transmission lubricant levels are satisfactory If oil is below filler plug add oil to the carrier as required then check the lubricant level in the transmission by removing its filler plug Replenish as necessary CAUTION Under no circumstances should any lubricant containing active sulphur be used i Also do not use mineral oil Only SAE 80 Multipurpose Gear Lubricant should 6e used SERVICE C SERVICE REF All service operations relative to the four speed j transmission should be performed with the transmission removed from the vehicle and separated from the power train Transmission controls can be serviced without disturbing the power train and therefore are listed under Service Operations Transmission In Vehicle immediately following SERVICE OPERATIONS TRANSMISSION IN VEHICLE Gearshift Lever Assembly The removal overhaul and installation procedures for the four speed gearshift lever are identical to those provided earlier in this section for the three speed transmission However the four speed gearshift lever does not embody the seat fig 6D 2 used in threespeed gearshift levers ND ADJUSTMENTS Oil Change At the end of the first 1000 miles and each 10 000 miles thereafter oftener under severe dust or service conditions drain both the differential carrier and four speed transmission by removing the drain plug provided in each Reinstall the drain plugs and refill each unit to the level of the filler plugs with SAE 80 Multipurpose Gear Lubricant SHIFT LINKAGE ADJUSTMENT After any service operation in which the shift control rod in the tunnel has been replaced or it has been found that transmission response is improper to the shift pattern adjust the shift linkage 1 Shift the transmission to fourth then loosen the coupling clamp nut fig 6D 3 on the tunnel shift tube 2 Move the gearshift lever its full limit rearward in fourth or until it is resting against the edge o fhe seat then tighten the coupling clamp nut on the tunnel tube The shift lever will not touch when a person s weight is on the seat 3 Test shifts in all ranges WERATIONS ERENCE GUIDE Shift Control Rod The removal overhaul and installation procedures for the four speed transmission shift control rod are identical to those used for the three speed transmission which are provided earlier in this section TRANSMISSION REMOVAL AND INSTALLATION Instructions for the removal of the power train from the vehicle and the separation of the transmission from the power train are provided in Section 6 DISASSEMBLY OF TRANSMISSION 1 Remove six bolts securing front cover and eight bolts securing side cover and remove covers from case
