I write:

"Yep, if conductivity is lost between the oil pressure switch, the oil light stays on."

No, incorrect, wrong, nope. Sorry.

The oil switch light, when encountering the rising oil pressure to the threshold, open the switch (circuit) and loses connection to ground, so the instrument cluster oil pressure light is off.

D'oh!!!!


Also, you'll need to know how to flush the coolant-compromised transmission fluid in the transmission and throughout. Much fluid remains in the torque converter, yet as your pulling it all owt, should be easy.

You do not want any remaining coolant anywhere transmission fluid and engine oil should be.

Also, separating the transmission dipstick tube where it secures and seals at the transmission fluid pan can be a real (I'll be polite) bother. Be careful else you can screw stuff up. You'll need to drop the pan, inspect residues and hope for no chucks or heavy wet clutch disc grit.

I dunno whether your state, where ever you reside mandates emissions testing. Yet using the blue coolant (did you use a silicate-free coolant?) may mean the catytlit convertor should be okay.

Though when you get it back together, running and driving, check the OBD codes for engine control sensor and device faults.



Oooop. Ha-ha! I'm a dyslexic SOB. Yes, an SOB. Meet my mudder and you'll see!

SOB Boyeeeeeeeeeee

And now, time for something not so different:
