July 3, 201312 yr My 2004 Outback was shifting at the wrong times. Took it to a transmission specialist who wanted $3,000+ to replace the transmission. Bought a transmission off a wreck with only 100,000 miles on it, and had it installed by my mechanic. Same problems. I'm now thinking it is the tcm? Any hints? Should I look for a replacement tcm?

July 3, 201312 yr What year was the trans from? Hopefully an '04 as well, otherwise your AWD will also be acting up... If you try another TCU it must come from an '04 as well, '05 was the all-electronic 4EAT (I think) and from my troubles I know the '03 TCU is unusably different as well. Can you be more specific about the problem? Lastly, if your old trans is fine, you can get a fair number of bucks for it.
