Noisy NP435 shifter
I replaced the shift fork pads hoping that would address this. No bueno.
My shifter still vibrates/rattles at highway speeds. It's loud and obnoxious.
The transmission shifts smoothly, and there doesn't appear to be any excessive play in anything. Any other ideas for cause/fix? Hoping to not have to tear into the trans. Doing the shift fork pads is about the extent of my capability right now.

NP435 shift lever retainer cap (B8T-7220-D) has two notches, is retained to the shift tower with two pins.
To remove this cap (trans in neutral), it must be pressed down by hand and held down while turning it counterclockwise to remove it.
People unaware use pliers or channel locks to remove it, which tears out one or both of the notches. Not pleasant!

Any pictures or diagrams that show this? Hope you're on to something!

I've known about this problemo since the early 1960's, been typing the info on FTE since day one, as this was the first part number I listed.
An FTE members truck had broken down on a NorCal freeway near Vallejo, his NP435 shift lever had popped out of the tower.
I told him what the problem was, found one a these caps at a local dealer. He bought it, then the dealer delivered it to him.
He installed it and away he went, happy as a clam.

Searching for it now. It's an obsolete part, and the places I'm finding that do list it show it's for HD trucks from the 60s, but I assume it would fit any NP435?
Now I just need to find it....

Carpenter has the largest quantity, most of the other sources only have one or two.
CARPENTER NOS OBSOLETE PARTS in Concord NC has 35 = 800-476-9653.
At one time, NAPA and indie auto parts stores also had this puppy.
---------------------------------------------------------------------------
B8T-7220-A =
MCDONALD OBSOLETE PARTS in Rockport IN has 4 = 812-359-4965.
No one else has this original part number, because it was replaced in 1988.
1988: FoMoCo changed the package quantity of a gazillion parts.
When the IDIOTS did this, they changed the part numbers suffixes, rendering all the previous part numbers obsolete.
