Where is the transmission Input Speed Sensor located?

Hi all, thanks for taking a look at this issue, ultimately, I'm in need of a photo or diagram showing where this particular sensor is located.

The issue is cruise control stopped working, couple thousand miles later, I noticed the speedometer not moving and stuck at 0 while the van was driving about 30 mph then started working again but seems to have a delay. Accelerating from 0 takes about 3 seconds before the speedometer needle begins to move.

I have already changed the Speed Sensor that is in the rear differential, still no cruise and same lagging speedometer issue.

Thanks a ton for any advice!
