Frank, I have the complete set of service manuals and there not cheap unless you can find them on Ebay. Go to www.helminc.com to find how to get them. One of the manuals that is very helpful is the Escape Hybrid POWERTRAIN CONTROL/EMISSIONS DIAGNOSIS. I would recommend it first if you don't want to spend alot.

And yes, the electric motors and generator are a part of the ECTV (Electronically Controled Continuously Variable Transaxle). This makes a repair, a replacement of the entire Transaxle much of the time.
