Wait, is your goat in the tranny too?
needed to use something as a binder for the cement. the gooey bits are also excellent lubrication for the tranny internals. this changes everything, you should have mentioned the goat from the get go. youre gonna be fine. the goats coat will soak up all the cement, its guts are gonna lube the transmission internals, its probably going in reverse because the goat was doing the moonwalk, now that its a mushed up pile of goo the tranny should be back up and running, and the cement/hairball binder should pop out through the tailshaft housing under normal driving. dont waste the maddog 20/20 on the trans, do the right thing and give it to a 12 year old.

Replaced it with a power-glide that uses Vaseline and ground up baby seals for fluid and has two reverse forward clutch drums so it runs forward in double reverse ?
