Repairing a leaky overdrive servo seal

[RRandal]

I was wondering how difficult it is to replace the seals on the overdrive servo. It is pouring tranny fluid out by the quart.

The cap has an O ring seal. If it is leaking you may have a cap issue. The OD servo is unitary, it has no replaceable seals.

I suspect your have an O ring seal failure in the cap. You need to compress the cap inwards and remove the snap ring to replace the cap O ring seal. In the area you have to work, not a fun job.
