Wow, lots of great information! So, I guess I have two choices. One, take a guess and go with the mercon and cross my fingers hoping type F is not in the converter. Two, drain the converter if I can find that plug. Looking at my truck this morning I saw the inspection plate which is about 3-4 inches long and about 2-3 inches tall. Is this the dust plate? Or is the plate the larger piece which covers the entire flywheel? Sorry for all the questions guys but I truly appreciate the input.
