Questions: Fluids and Wiring

For sure, the Borg Warners need the right stuff, as they used fiber backings on some internal parts. Tremecs, with the exception of some early transition units, did not use the fiber inside, and could use a different oil. I think thats where some confusion comes in. People may think T56's are all the same but they are not. Also, there were running changes and upgrades through the years that caused specs to change. In the end, you still need yellow metal friendly oil, though.
