I have a small leak on my C-6 where the trans kick down /shifter linkage/ Neutral safety switch come though. Was told it was an O ring . Anyone have a part number or size so I can get a replacement ? Anyone have picture or a diagram? Thanks
These are the two part #'s you need:
D5AZ-7B498-A Oil seal (manual control lever) 73-up F100-500 C-6 6&8 cyl.
3/4" ID x 1 11/16" OD x 7/32" thick
386078-S Seal (throttle control oil) 73-up F100-500 C-6 6 & 8 cyl.
3/8" ID x 15/32" OD x 3/32" thick
The first one is a seal, the second one looks like it's just a standard o-ring (that's why it's just an standard hardware p/n ending in "s" rather than a normal Ford style p/n).
From looking at the parts diagram it looks like you have to drop the pan, remove the valve body then remove the neutral start switch and the inner and outer shafts.
