I had a tranny go out on one, but it was my fault for not checking the level, it was my 81. The seals on the output shafts leaked as I drove and "spit" it out, so I never saw a puddle.....First time I saw an early Subie I had just hole shot my pile of mud from my 4x4 truck and covered my buddies windsheild, I was on the floor laughing as the SPARE was under the hood over the transaxle (had to remove it to check the tranny fluid, hence my not checking it).
Thanks for the update on the head gasket, I had not heard that....
