In 1996, GM produced a newer version of its electronically controlled 4L60E. This
4L60E transmission is 21-1/2" long, and has a removable bellhousing. It has
a hex bolt pattern on the output side of the transmission, similar to a
TH400.
The kit which you have purchased was designed not only to adapt
the 4L60E to the NP231 case, but also to maintain the pulse
generator to run the computer. We have included a 700R4 shaft in
this kit to be installed in the transmission. Once installed in the
transmission, you may begin to assembly the pulse system on the
transmission. First is the reluctor ring. This clamp-on reluctor ring
fits over the stock governor gear on the supplied output shaft. It
creates 40 pulses for each revolution of the output shaft for the
drivetrain control module. We have provided two reluctor sensor
locations to choose from in the adapter. The hole not being used will need
to be plugged with the brass plug provided.
