727 2-3 upshift VERY harsh
They (PTC) had it apart in about 10 minutes, but it took about 4 hours to get it back together. They installed a bolt-in sprag, and had to turn a couple of parts (drums, etc.) clean it up, and run it through their "dyno", a 6 cylinder engine with a couple of pressure hook ups and a drum attached to the tailshaft.
The valve body is the one that was in the tranny when I took it in. The tech mentioned it was pretty filthy inside, and took a good cleaning to get it in shape.
As far as I know, they used the lever that was in the tranny, which I assumed was stock, but I don't know for sure.
For the money and time I spent to drive it up there, 3 hours each way, I am not very happy at all. I will call them 1 more time, and adjust the kickdown band 1 more time, back off another 1/2 turn, but I am afraid this will affect the 1-2 shift quality at some point. FWIW, it did not do this before I took it in for service, but the convertor was slipping and leaking at the cracked hub pretty bad.
