need help! throttle binding-sticking / E40D hard shifting

[texasstroker]

Need a little help, looked for some post for this info but no luck yet.
Just bought another toy. 1993 FORD F-350 single wheel crew cab, 7.3L IDI non turbo, E4OD auto tranny with a 190-k miles.

Truck runs GREAT with plenty of power for a non turbo truck, and has a new injector pump. The transmission shift great and at the right time but it shifts hard in every gear including overdrive. Seems like when I put it in D or R it goes into gear hard also. Drove to a local tranny shop and they test drove it and said it seems as if some install a shift kit in the tranny. So I went to another shop just for a 2nd opinion and was told the same but also told I could adjust the shift a little by moving a part on the side of the injector pump. So I tried this adjustment and now the throttle is sticking or like it is binding up on something. I moved the adjustment back to the original location and still have a binding/sticking throttle.

So did I mess something up or what? Is there really away to smooth out the shifting on these trucks?

Ok, I fixed he binding or sticking issues and did get a little change out of the hard shifting.

How much adjustment can I actually get? Or is there any way to put it on a scanner to make the right adjustments?
