N4A-EL Erratic / Intermittent Shift Complaints
Several complaints such as 3rd gear starts, no upshift, falls out of third, etc. may be caused by installing the pan bolts in the wrong holes.
There is a total of 14 pan bolts for this unit. One bolt is shorter than the other 13 bolts. This special short bolt must be installed in the hole directly under the Inhibitor Switch. Using one of the long bolts in this hole will likely damage the inhibitor switch since it will extend through the pan rail casting and damage the switch.
