First, the negative battery cable should be disconnected so that the neutral safety switch (which includes a back-up light switch) can be removed and installed from 4T60 and 4T60-E Transaxles. On 1992-93 Eldorado and Seville, the air cleaner housing and duct have to be removed. The shift linkage, electrical connector, and vacuum hose must come off next followed by the attaching nut and shift lever. Once complete in this order, the fuel line bracket and bolt are to be taken out, followed by the retaining bolts and then the switch. Reverse these steps to install with adjustment of SWITCH as specified in Adjustments for Neutral Safety Switch above; tighten retaining bolts to 20 ft. lbs. (27 Nm). The process is similar for 4T80-E Transaxle except that the control cable at the lever on transaxle manual shaft needs to come out first, after which this control cable bracket at transaxle has to go. Following this step, remove retaining nut but leave transaxle manual shaft lever on top of electrical connector & hose then remove retaining bolts and finally neutral safety switch. Reverse these steps to install with adjustment of SWITCH as specified in Adjustments for Neutral Safety Switch above; tighten retaining bolts to 106 inch lbs. (12 Nm) and manual shaft lever retaining nut until it is tightened to 15 ft. lbs. (20 Nm). It is necessary that the neutral safety switch be adjusted so that engine will start in PARK or NEUTRAL only to prevent possible injury to person inside vehicle starting engine while vehicle is moving or not properly secured against rolling away causing injury or death due to collision or run-over accidents involving small children playing near vehicle wheels under driveway conditions which are limited visibility situations where walking slowly backward might be difficult without tripping on unseen obstructions such as toys left near garage doors obstructing view ahead while backing up at night; light switches cannot be seen easily enough due to darkness yet their position would prevent possible loss of life which could result if someone accidentally started automobile while children were playing outdoors near entryway into home or driveway leading onto street causing it to roll off hitting one or more individuals then running over them because they did not realize that there were people behind them at time when they put vehicle into motion since backup lights would not come on so person operating control switch had no way knowing otherwise. To adjust the neutral safety switch, loosen its retaining bolts, rotate transaxle manual shaft to NEUTRAL, and rotate switch until a 2.34 mm gauge pin can be inserted in adjustment hole. On 4T60 and 4T60-E transaxles tighten these switch retaining bolts to 20 ft. lbs. (27 Nm) or on 4T80-E, 106 inch lbs (12 Nm).

Ensure the transmission is still in neutral and use an alignment tool to properly position the switch.
