I think that's the same tranny -- mine's a 722.30-- and same kick-down solenoid. But the EPC shows two versions of the solenoid for your car, and a number of versions of the solenoid for my car with a host of footnotes and options I cant' make heads nor tales of.

Since my tranny was rebuilt last March, and is still under warranty, I'm going to take it back to the shop to see what they say about it.

I'm not sure if the warranty covers the kick-down. But If I'm lucky, they'll be able to tell me what the problem is and, hopefully, fix it. And if that's the case, I'll report back.
