Hey everyone,

I have just had my trans replaced with a used one at a genuine Subaru dealership.
I have a 2012 2.5i Premium EJ25 with a TR690JHBBA, however they replaced it with a TR690JHABA.
From my research the JHABA seems to be for the 2010 model only and the JHBBA for the 2011-12 models (Subaru's own website says this)
Does anybody know if its possible to put a JHABA in a 12 model??

The car seems to drive alright, we got it back yesterday afternoon (Friday) and I only looked at it this morning (Saturday) so service is closed and I'll have to wait until Monday to ask them about it.
My feeling is that my car was built with a JHBBA so that's what they should have replaced it with.

Thanks

Remember that your 'new' transmission went thru a rebuilding process before it came to you.

I did some research on differences between the early years for someone else, and the biggest delta was in the torque converters.

2010 H4 engine = 31100AB170 for TR690 CVT 31000AH630 TR690JHABA

2011 – 2012 H4 engine = 31100AB170, 171 or 172 for the TR690 CVT 310000AH780 TR690JHBBA

Chances are you received an older case that was updated with the latest, best possible components. They would then have applied a 'calibration file' to the TCU to make it all mesh up.

If it works and feels right, I'd say you likely have nothing to worry about.

Thanks For the reply,

I ended up calling a subaru transmission specialist and they said the same thing, also the valve body may not have been updated.
This isn't a rebuilt trans (which i would be fine with) it's from a wrecker so definitely an older model.

Any way, subaru acknowledged it's the wrong part and are sourcing the correct model for me without me even having to argue or anything so that's good.

where were you able to find this subaru transmission specialist? I have a 2013 OB with the TR580-KHDBA transmission, and I'm trying to figure out which other TR580 variants would fit in my car. There's a 30k mile transmission in a 2014 Legacy in my town for $1000. But I don't know if it would work, and I have not been able to find anyone to confirm if this would work. I'm not above swapping the valve body from my? current one to the slightly different one if that would do it.

Hey mate,
They are from Sydney... "All drive subaroo".
They were super knowledgeable, I had talked with nearly ten other mechanics and even ones that said they specialize in Subaru's but none of them knew as much as these guys did. They spoke with me at length over the phone, even without me trying to make a booking or anything. Just give them a call and ask them this question and they should know.

Good luck

There is also "Subaru Gearbox Australia" (In Peakhurst) however I couldn't get through to them and "All Drive" answered my question anyway so I didn't bother.
