Is the kickdown linkage set up right?
Whether you beleive (or not) that it makes any significant difference in the transmission's throttle pressure, is another story. I'll go by my experiences and you can go by yours as far as that goes.
Let's look at the geometry and then anyone who is interested can see how changes in position can effect the relative distances moved.
Here's a sketch of three links with first and third horizontal, connected by two bell cranks.
We can call position 1 closed throttle, and the other two half throttle and full throttle respectively.
If everything was drawn perfect (its not) the distance travelled by the the first pin would be the same as the distance travelled at the last pin.
Now what happens when the geometries are changed?
Here's one example to illustrate.
Here's an extremely shortened intermediate rod.
Yes, extreme - because its easier to see.
The throttle rod is kept the same, and the lower rod has been rotated with the bellcrank.
Not really. Bellcranks are sensitive to geometry.
