I have a 2008 Legacy, 2.5 NA engine, 4eat auto transmission.
The car has 134k miles. Transmission failed, and needed replacement.
The CV axles were replaced 6 months ago with the HD Duralast axles from Autozone.
I got a used transmission from the salvage yard, has 64k miles on it.
My head gaskets were leaking badly, so I figured since the engine and transmission were going to be separated, I'd pull the engine too and fix the head gaskets.
I installed the new transmission today, have not reinstalled the engine yet.
So here are my questions:
1. The torque converter from the new transmission has some slight surface rust on it, so I think it was exposed to the elements. I think it is fine to use, since it has significantly less mileage than the original one for my car. Any reason not to use the torque converter that came with the transmission from the salvage yard?
2. Is Subaru branded transmission fluid necessary? I've always used the Subaru fluid before. Wondering if there is a cheaper, local option.
3. I know with new head gaskets, I can use the blue Subaru coolant, instead of the older green style. Do I need to use the Subaru branded stuff, or is there another coolant that can be used?
4. In order to unbolt the torque converter from the engine, I had to remove the upper intake manifold from the engine. Is that normal, or did I miss something and do something stupid and unnecessary?
