Default Auto box speedo sensor seal

Just replaced the tail shaft seal on my 94 auto, but have noticed a small leak from the speed sensor unit where it fits into the gearbox housing. I don't have a factory manual, is seal easy to change and do I need to take any precautions before removing the sensor???

Just the one bolt you see then pull to remove the sensor, the O ring is
PN 15552872, doubt you will lose more than a few ounces of fluid.

Ijust replaced the o-ring on mine a few weeks ago. Very simple.

Take out the 10mm bolt, twist and pull the sensor out. Have a pan under it, although not much comes out. Replace the o-ring and slide it back in. Done.
