How to replace the Neutral Safety Switch, manual shift shaft, detent lever, and position switch assembly in an Allison automatic transmission on Chevrolet Silverado 1500?

Before you can replace the manual shift shaft, detent lever, and position switch assembly in an Allison automatic transmission, start by taking off the control valve assembly. You need to take out the detent lever/IMS retaining bolt with a T27 TORX(R) bit, and discard it, because it has patch lock material on the threads. Be sure not to scratch the transmission case surface near the spherical pin as you remove it, and do not twist the pin to keep it from getting damaged. Set a protective cover on the spherical pin before you take it out of the transmission case. Feed the manual shift shaft through the detent lever/IMS assembly and seal, rotate the assembly, and take it out after the park pawl apply assembly comes free. Installation requires putting the new detent lever/IMS assembly into the case, mating the park pawl apply assembly, and sliding the manual shift shaft through the seal and assembly. Slide the manual shift shaft all the way in, fit in the spherical pin, and use a T27 TORX bit to tighten the detent lever/IMS retaining bolt to 10 N.m (92 lb in). Afterwards, put the control valve assembly back, then run the FastLearn process through a scan tool to update the TCM adaptive values for the new components, so old adjustment times do not continue.
