Leak from 72c trans

[Dpflood]

The leak is coming from behind the forward and reverse control arm?

How do I fix

That depends upon where it is coming from, very exactly.

Take a look at this parts diagram...

Maybe parts 32 and, especially, 38?

Basically my best present guess from the description is to remove the control valve and change the o-ring.

The leak is coming from between 23 and the body.

It is an Oring, have to remove valve body to get shaft out.

Yup. The two parts I pointed out and the instructions sdowney717 posted. The original is the key part, the other is a just in case part.

Putting some pet. jelly on the detent ball makes it easier to reassemble.
