A few questions for the experts:

1. Is the drain plug magnetic (I think not, please confirm)?
2. Where is the factory temp sensor for the dash light in regards to the oil flow path?
3. At what temp does the dash light come on?

 

[Malleus]

1. yes
2. in the outlet line on the right side of the transmission
3. 302°F
