#11 of 20 Re: ELECTRIC MOTOR / TRANSMISSION [stevewa] by sarahfromsc Oct 19, 2005 (7:54 am)
Replying to: stevewa (Oct 19, 2005 12:03 am) Oh, and this is a PS:   I do like the little suv, it handles well, the interior "fits" me, and it fits my lifestyle. I just feel a little snake bit at the moment. So, I don't want anyone to think that I am bashing the hybrid, just questing for knowledge so I can go to the dealership and offer suggestions, or at least be able to ask intelligent questions!

Replying to: sarahfromsc (Oct 19, 2005 7:44 am) Given the symptoms you're reporting the tranaxle (transmission in a FWD based vehicle is referred to as a transaxle because it includes the differential) is likely the culprit. The other possibility is the PCM (computer) but it sounds like they've eliminated that possibility to their satisfaction...the PCM is much cheaper so they'd try that first if there was a chance of it being the problem.   You should NOT be seeing the behavior you describe.

Replying to: stevewa (Oct 21, 2005 10:30 pm) Thank you again for clarifying! Lordy, am I learning a lot.   I hope y'all do not mind one more question. I have the new transaxle in, now my gas mileage has dropped from 27 miles per gallon to 23.5. I know I said that 27 stunk, but 23.5 really, really stinks. Is this because this new transaxle needs to "break-in"? Replies to this message: stevewa (Oct 25, 2005 10:36 pm)

Replying to: sarahfromsc (Oct 25, 2005 4:52 am) More likely it's because they did a lot of engine idling when they were working on your car   The computer will have to re-learn fuel trim and the like so the first few tanks might be sub-par. Good luck...hope they found the problem.

#16 of 20 MPG dropped suddenly by nsupp Dec 02, 2008 (1:38 am)
As I was driving up to my home in the Virginia mountains I noticed the mpg's dropping suddenly from 27.7 to 22.5. It just tanked. I reached the top of one of the hills and coasted down and the mpg's increased, then dropped again as I drove up the hill to my house. What is happening and if I leave in the AM to go to work what should I expect? Thanks for any help you can give me. Replies to this message: bdyment (Dec 02, 2008 4:51 am)

Replying to: nsupp (Dec 02, 2008 1:38 am) The engine is using a lot more gas going up the hill. A lot more power required. Uses almost nothing going down. The read out is simply stating that fact.

Replying to: stevewa (Oct 21, 2005 10:30 pm) I have a 2005 Escape Hybrid with nearly 150,000 miles. It drives great and I am averaging 30 + MPG but sometimes when I am going up a steep hill the transmission will rev to 6k or more. It never seems to "slip" but I'm concerned because I don't know if that is normal or not. Should it rev that high under a heavy load uphill?
#19 of 20 Programming New eCVT ??? by escape6 Aug 26, 2009 (5:43 pm)
My 2006 FEH required a new transmission according to the local Ford dealer, however none are available through the Ford factory channel. I was told I would have to have one custom built in Japan at a cost of $14,000 and delivery would be uncertain. My dealer said try and find one out of a wreck. After internet searches, I bought a new one from a surplus dealer who bought 3 from Ford factory surplus... The Ford dealer cannot get this transmission to talk to the car. The tech spent 2 hours playing with it and got nowhere. Anyone else had this problem? The parts guy says there were 4 different transmissions and not all are compatible... However this was a "new" transmission so it had no previous "connection" to any other vehicle. The issue seems to be a computer looking for "as built codes"... However since my new transmission has never been installed, there is no VIN associated with it. When I see the hassles with FEH, I wonder how much time the factory spends with a new FEH programming all of the stuff to work together. This critter is worse than Windows 95 with a homemade computer. and plug & play cards...   I need help...   Rocky
#20 of 20 Need Help hacking 2006 FEH Transaxle/repair by escape6 Sep 06, 2009 (8:56 am)
Dear Listers,   We have a 2006 Ford Escape Hybrid with 37,000 miles which spends most of its time in the shop or riding around on the back of a tow truck. Our Escape was an insurance write off at 2300 miles and we bought it at 3,000 miles total time running and repaired without warranty. I need to talk to someone who is an expert on the Japanese transaxles used in both the Escape and Prius vehicles. My Escape transmission is gone south (supposedly) and we bought a replacement transmission (brand new surplus) which won't talk to our car properly. The issue relates around the computer security system (PATS). It seems our old transmission was PATS and the new one I bought is non PATS. PATS has to do with the encoded key systems. The FEH has been at two dealers for 5 weeks now and we are no closer to solving the problem(s). The dealer is advising against ordering a factory transmission at this time.   The issues with these Ford Toyoda aisin yes I mean aisin not Asian ECVT transaxles is that 1. they are not dealer serviceable, or transmission shop serviceable, 2. they are not depot serviceable 3. there don't seem to be any service manuals out there for them, 4. new ones cost $14,000 Canadian and have to be custom built in Japan, 5. neither the dealer nor I are sure the real problem was the transaxle in the first place.   Since I did not have to return my original ECVT transaxle, the question is if we remove the "New non communicating non PATS transaxle" can we rebuilt the old one that has PATS incorporated in it? in other words take two transaxles apart and build one working one. or is there any on this list who can hack the toyoda code on the ford transaxle? I assume these codes are some kind of machine language rather than Japanese commands?   From the fleeting glances I have made at some of the edmunds messages I suspect there are guys and gals and mechanics, engineers, and programmers on this list who know this stuff or know people who know how to do what I am talking about. Anyone who has taken apart a ford escape hybrid or toyota prius transaxle and found what caused it fail please respond as well. If this is a hopeless project these comments would also be welcome. We deliberately have not messed with any of the Ford transaxle guts. It is unbolted and sitting in the dealer shop on a bench and looks just fine. The output shaft looks new...   Please respond directly to Rocky at Tya24-fly.net   Rocky near Edmonton, Alberta
