1985 BII Tranny Question

I have a 1985 Bronco II 4x4 automatic tranny with overdrive ( A4LD 18 bolt). Does anyone know if there is a service bulletin about tranny failure. The front seal seems to pop out under pressure. Anyone ever hear of any front seal oil pump failure?

Also, I am in need of a diagram of the front of the tranny.

Any ideas are appreciated.

Yep, they are a POS. They die all the time. Good luck finding a shop that can actually rebuild one properly.

Or do what most do, save $2,000 on an iffy rebuild, and swap in a 5 speed.

Some shops apparently do know what they are doing and can do a decent rebuild on the A4LD. The problem is finding one. And it'll still be expensive. I asked some folks I knowaround the Texarkana area early last year that are rough on trannies and kept coming up with the same shop which also does the local Ford dealers warranty work. $1400 later and mine has worked like a champ since.

Check out your first post"what gear for the a4ld tranny"
Ford has and updated bellhousing and front seal. The bellhousing has an added lip design so the front seal can be staked. Also the updated bellhousing has an obstruction removed from the drain hole to allow better flow. The crank to flywheel spacer can be sometimes damaged not allowing true center of the torque converter hub, allowing seal and bushing failure.
There are some TSBs on the front seal blowout and those parts cover them all.
