Ultramatic Shift Lever Seal

Well I'm eliminating one leak at a time and now ready to tackle what the Ultramatic Service Manual refers to as the "Control Valve Lever Shaft Seal". It appears to be item number 3.590 and the seal is #421326. Replacement of the seal is listed under the "Troubleshooting" section as one of the leaks that can be repaired without removing the transmission but all it says is remove the pan and replace the seal. Does anyone know if there are any complications involved with the procedure? it looks like the shift lever shaft slides outward and then the seal is externally removed from the casing.
