NOTES:
1. Before assembling the new transmission shaft into your 4L60E, you must verify the spline size of the new shaft and the
input gear of the new process transfer case. The shaft is available in either 21 or 23 spline tooth count.
2. Be sure that the adapter shaft and T/C input gear do not bottom out prior to the adapter meeting flush with the
transmission. Some models may require the output shaft to be shortened.
3. The adapter has provisions for a new seal (NAT #456057). The outside diameter is 3.75" and the inside diameter is
1.937". The seal must be installed with the open side towards the transmission.
