2013 ECVT Replacement Options

I am getting a whine out of the tranny, mostly in EV mode that seems to be getting louder. I am at 122,000 miles. I spoke to dealer, if I replace tranny at some point, it is $7,000. I found this used tranny, but the vendor says it won’t fit: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F312556789027

It is from a 2017 which I thought would fit and work in my 2013?

I don’t know that I will even need a tranny, just weighing options. Funny, this vehicle has basically zero value ($1,500 offered on a trade in). It has been one of the best cars I’ve ever owned, but have to face the problem of this tranny possibly going out. Any help or pointers to tell me if I can put in a later model HF35 into my 2013 SEL Hybrid is appreciated.

Thanks

As an update, the howl is the same howl that this car had when new when on hard regenerative braking, except much more pronounced. I only get the ‘whirring’ on EV mode and Regen. Maybe this bearing is just wearing in? As I mentioned, the ATF looked pristine, and IDK if the drain plug is magnetic but it had nothing on it. Maybe I have some time, car functions fine in all driving parameters.

Your symptoms do sound like mine were but, of course, I can't say if its the same problem.  Here's more detail on my scenario:

  • My first set of tires became very noisy and were changed at about 72k miles.  IIRC, it was after that change that we could again hear a faint whine during regen.  At the time I assumed it was normal (do other folks have this whine during regen?) but perhaps I already had a problem.
  • Sometime after, maybe around 110k miles, one could also hear a whirring sound during EV that came and went with load - sound present when pressing accelerator.
  • Changed ATF at 155k miles and was surprised to see it was rather black and had a few specks of metal(?) in it.
  • Sounds continued and transmission failed at 176k miles with serious leak while driving (it didn't drip while just sitting).

At all times the sound was not very loud - I expect some folks wouldn't even notice.  If your fluid looks good (clear with that red tint), then you may have quite a bit of time (??).  I would suggest checking the color at least every 10k miles.  I don't know about the drain plug either but there is an internal filter - but it won't stop a change in color.  Once a leak starts its all over.

SnowStorm,

What route did you take on R&R the transmission, Dealer and New? I agree with your diagnosis, I may have many many more miles. At least a year. My ATF was very clear red tint. My thoughts are a salvage HF35 from a newer model C-Max or Fusion and have the dealer do the swap.

Salvage on Ebay’s are $1,500 including freight. Dealer New with labor is $7,000...

I have so loved most everything about this car, I just can hardly stomach $7,000 for tranny and labor for a car that is barely worth that amount down here in Texas.

Thanks for the input, let me know how you went and how it’s acting after the replacement tranny.

R&R?  Please follow link in post #2 above.

Oh yes, thanks for the reminder. I had already read it... But slept since I suppose, very good data and just what I need.

My big question, and I may start another thread to cover this, but it seems as if Toyota’s hybrid drives seem to run for quite a long time. In covering their blog sites when looking for towing info, they don’t talk much about the hybrid drives (ecvts) going out.

The C-Max and Fusion do have more power, but certainly Ford prepped the HF35 for that.

Just thinking out loud in light of my situation...
