2008 Prius with new 12 V battery won't shift; lots of warning lights

she's not a member, afaik.

 

Thanks for sharing!!

Had never heard of this before (is it posted/stickied elsewhere?), so I went out and plugged in my elm237 and fired up Torque.. then felt good about MG1 being higher

 

I think what Bob was meaning, was that if (when) you need to do a transaxle swap there will be plenty of choice from the pool of write-off flooded Prius in Texas and Florida.

 

That is what Bob is saying.

 

The transaxle is well sealed so after cleaning the exterior, it should be perfectly fine. A/C compressors too. But the engine and exhaust assembly, not so much. Electronics would also be suspect, not impossible, but not something high on my list. No seats, interior, or body parts would be trusted.

The expected database errors are making it hard to render the images but this is an excellent outline:

Windings shorted are a lot more than likely to have a different amount of resistance. And
I thought I explained why there’s shaking in my last post.

I was quoting your post where you said you had a dead shorted winding to ground and you drove 25 miles
With no issues. That is very hard to believe.

I would imagine if the winding is not shorted directly to ground as you state it could be leaking slightly by pinhole in winding coating and intermittently flashing/conducting to ground but most wind8ng failure in a g2 almost instantly becomes catastrophic as it will flash over and burn the whole winding pack. The windings are tightly packed together and as you know at hundreds of volts ac per winding and very high current.

But if extremely intermittent I would imagine you could then cause it to fail by driving the car extremely hard for a moment. Floor the car from a stop really hard. That would cause maximum current and load applied to the trans.
Any flaw in high volt isolation in the trans will immediately occur.

Drive it like you stole it. See if it logs an iso fault.

 

I like them but then I'm not the 'average bear.' They changed the transmission fluid and gave me a good sample. They didn't deflate my tires but let me know they were high. They also looked at the plastic quarter panel and explained why it didn't 'snap back in' (cosmetic for now but I may try to solve another day.) Their labor rates may seem high but we're also paying for competence.

I recommend making an appointment and take hardcopy of the significant posts and references in a folder. Ask them to confirm the diagnosis and give you an estimate. Make sure the car has P0AA6 on the controller when you drive there. Then you'll have something to compare with Bill Penny.

For a third estimate, I'd call AutoBeYours and see if that makes sense. With AutoBeYours, there would be adventure of getting the car there; leaving it long enough for a repair; getting back to pick it up and; the adventure of the return drive. I suspect the car can get there but would have a second one following to handle any issues on the way up. Drop off the car and return. It would be an adventure and I've not visited Steve before and both of my cars have receiver hitches. However, a U-haul rental might work too.

Suzy do as I suggested go drive the car hard. Floor it at a light a few times and keep if floored for a while.
That will provide maximum voltage and current to the trans and will expose any hi voltage issue suspected.

Note how it drives if it throws a code on the dash.any minor drivability issue will quickly show itself.

You cannot hurt the car doing this. Make a video.

 

I also monitored MG1 and MG2 temps on my 2004 with 289K. My car runs fine with no leak codes. I drive it hundreds of miles in a week. MG2 temp ran consistently higher than MG1. The largest spread I saw was 77 to 93 degrees.

So either Bob's test is invalid or I also need to replace the transmission in my car.

 

Posts like this one of the reasons I refrain from posting about a car not on my driveway. My hands-on experience is with Gen-1, Gen-3, and Prius Prime. I also have experience with failed Gen-1 transaxle. But I don’t hang in Gen-2 forums because I have no way to replicate other observations.

If your car is within a hundred miles of Huntsville AL, I would enjoy documenting your experience. Perhaps some photos or screen shots?

Please can you explain how you were able to interprete the H141T as Jan14, 2016? Would love to learn that.

 

Y not invest in a tech stream software to help with the diagnosis? That would help forum members contribute more.

 

If you read all 200+ comments, you'll notice she already did that.
