I just noticed that when I push the slipyoke sideways it moves a wee bit... So I figured that it must be a bearing or bushing inside the seal that's waisted, right? The trans is an -89 A500 / 904 with o.d. from a van. (& it's been working fine in 8 years now in its new home) So what's in there; a bearing or a (bronse?) bushing? & nope, no leak yet.
