Awesome write up, some good points made hereI'm going out on a limb here, but I suspect Steeda's assembly order / instructions may just be based on mimicking the standard setup (and not allowing for the change in shaft diameter as highlighted).
I've been looking at the standard setup including the lock out collar, in an attempt to get rid of my high RPM (7k+) shifter buzz.
From what I can tell (and if Ford would have assembled mine correctly), that white spacer is held down by the o ring, and the o ring is held down by the standard reverse lockout collar when it's in its lower / home position i.e. even if the spacer and o ring move up a little when the collar is lifted and reverse is selected, they will get pulled back down the shaft by the collar when it returns to its home position. The o ring also acts as a buffer / isolator between the white spacer and the lock out collar.
Note that the standard collar does not have the upper internal o ring like the Steeda collar.
I think that my rattle was coming from the incorrect assembly i.e. my shift collar sitting directly on top of the white spacer, coupled with the following :
- No internal o ring in the top of the standard collar.
- My change of shift knob to the Ford Performance version (no leather wrapped up inside the internal bore to act as a buffer / sound deadener to the standard shift collar).
The replacement Steeda collar appears to be designed to operate in exactly the same way as the original (with regards to keeping the o ring and spacer down in position), but has the added benefit of having a second internal upper o ring to keep the top of the aluminium collar from contacting the shaft, therefore adding additional sound deadening / metal part isolation In that area.
Now if you change any of the components in that area, and those changes affect anything to do with the shaft diameter and / or the relationship of where the collar upper internal diameter sits on the shaft in relation to the roll pin hole, something else needs to change to accommodate the new / modified parts ...
Some random pictures to help with understanding the above, and to brighten up what might have just been the most boring post I have ever written on this forum ...
Standard and Steeda components - note that the bottom of the standard shift collar has been removed as it gets broken during removal of the standard shift boot :
Standard (MT82) shifter :
Standard assembly order (I think) :
Spacer and o ring position after fitting the standard collar in the home / bottom position (same position with the Steeda collar) :
Not the easiest thing to remove, it needed a bit of glue afterwards ... :
A right pair of knobs :
All done (and my 7k buzz has gone) :
As I’ve seen a few posts in the past asking - mine takes 11 full turns (approx 14mm of thread engagement) to sit in a nice position that still allows easy engagement of reverse. 12 turns still worked, but the ridge on the collar was right up to the underside of the knob.
11 turns, and reverse :
The only problem I have now the buzz is gone, is the loss of my audible 'shift now' warning ...
Note for anyone doing this mod on the standard shifter : ensure the roll pin is centered in the shaft :
If that pin is not centered, there is a chance it will cut into the inner bore of the Steeda collar (possibly adding NVH ?) :
Those marks aren’t from my assembly. I bought the collar from another forum member who was selling up, and tidied the finish up a little before fitment :

I have to admit that now everything is working properly on mine, I’ve fallen in love with the shifter all over again, it’s one of the best things about the car so props to the Steeda engineers
I also love how much lower the knob sits compared to stock
