2007 GT auto transmission question

[Stifull]

This car doesn't get driven much but I was using it today and noticed on 2 occasions when i had it in SS mode that there was a shudder when it went from 1st to 2nd.. I checked the transmission fluid level in park when hot with the engine idling and the fluid was about 6-7 mm below the 'LOW' hot mark.. I forgot to smell it but the color was good. I'l smell it tomorrow.. What oil does it take, is it a big internal, make a huge mess type panel filter in behind a dozen screws and gasket or a normal easy to swap engine type oil filter.. If it is a panel filter type I am tempted to top it up via the dip stick tube.. I did use search but I got mostly posts about power steering stuff or Yowie's Forester which is probably different. I am quickly getting to the stage where I am tired of working on cars. We have 14 cars here and 4 of them are project or dead cars belonging to my sons who also have bikes or company cars as well so there is no incentive for them to do anything with the dead ones. Thanks for reading..

I take our cars to Western Suburbs Automatics (Rocklea) for services (incl power flush) - which are reasonably priced.

There are probably options closer to your place.

Letting the auto trans people do their thing might be more fun that crawling around under the car & tinkering with that stuff.

Thanks mate. I have no intention of messing with 5eat ! If I knew what fluid brand grade etc etc I would top it up but as I do not know that I will get Subi Evo to do it. Their prices and expertise are very good.

An update about this issue, I had the oil in the 5eat changed as well as the diff oils as the transmission has, during winter, been very jerky for the first 1-2 klm then once warm it is smooth and if it wasn't for the engine noise you wouldn't notice the changing. The morning after the trans oil was changed last week I started the car for the first time, I only got about 500 meters and several lights on the dash came on, cruise, traction control, CEL and oil temp light .. I drove it over to Subievolution and Russel put the MUT on to check for issues and it said that sensor 1 which is an external sensor and sensor 2 which is an internal sensor both showed up.. Russel cleared the codes , turned it off and then restarted the car and within a couple of seconds the lights were again flashing and it was the external sensor again. He again cleared the codes and the lights haven't come back on despite several 6-10 klm trips. The jerking gear changes are still there for the first few minutes and then it is perfect again. I have found that as I am allowing the engine to warm up I put the transmission in Neutral the trans warms up a little and the jerking is not as bad but is still there. I am not keen on buying a new external sensor if it turns out to be the internal or visa versa .. If anybody has a known good external one they can supply to help with diagnosis and potentially sell me I would much appreciate it. We have to go down to Sydney for a wedding on the 4th of next month and I would much prefer to drive down in the Liberty than my WRX which just had it's timing belt kit replaced today as it was due and I didn't want to start out on a 2500klm round trip with an overdue timing belt but I still have 12 days to get the Liberty sorted. I hope someone here is familiar with this issue and knows the fix..

Depends exactly which sensors you’re talking about, the specific codes will describe which.
If it’s turbine speed sensor, the parts are generic and available affordably on eBay, iirc this also applies to the transmission solenoids.
Related info in the links below, bear in mind they’re Jatco transmissions made for a range of makes, Subaru, Nissan etc.
Some insight can help avoid a massive gouge from some transmission specialists…
You might also perform a transmission relearn, either now or after any repairs.

I’ll paste what resources I’ve saved in notes:

Reset relearn

What year model?

Generally:
5eat models around mid 2000’s onward, use FreeSSM PC app with Tactrix or Vag-Com KKL 409.1 OBDII vehicle pass through interface to initiate TCU reset:
with the car on a hoist and the wheels in the air, engine idling, run through all gears then reverse.

5eat transmission power flush: viewtopic.php?f=17&t=26562

4eat models: use the FreeSSM reset then immediately drive using various gears, loads and rpm.

Update the first generation 5eat software:

The pak file can also help with P0771 and P1798 DTC codes:

CVT: Matt (throttlehappy) fuzzy logic reset…
Disconnect battery.
Put foot on brake for 10 seconds (drain electrical system).
Reconnect battery.
Turn ignition to "ON" position.
Turn ignition "OFF".
Turn ignition to "ON" position.
Turn ignition "OFF".
Wait 15 seconds.
Start car.
Idle for 60 seconds.
Drive for 30 minutes on light/moderate throttle.

For idle relearn, DBW engines, reset the ecu with a cold engine, idle until fully warmed up with no haptic control input eg no throttle, no steer etc, all accessories including AC off.

For fuel and knock/timing correction *relearning*, take the car for an off boost drive for 20 minutes or 20 miles, then drive normally if idle total fuel trim is within +/-10%, ideally less than +/-5%.
Ideally the process will be data logged, meaning fuel trim range, feedback knock and knock correction can be seen in context with load boost and rpm.

Be sure to follow the Diagnostic Trouble Code (DTC) procedures which you can find in your year model Factory Service Manual (FSM): viewtopic.php?f=6&t=34980

Turbine speed sensor more info:

Turbine speed sensor

You might be using a generic OBDII interface and app or scan tool to read engine DTC codes and if Auto transmission get P0700 etc.

Bear in mind this is a generic OBDII Diagnostic Trouble Code (DTC), meaning Subaru specific codes might be stored in the ECU.

So you might find a mechanic, tuner or enthusiast with a Subaru SSM level scanner or display your engine codes on the odometer.

From memory the fault is associated with the transmission turbine speed sensor which is located in the valve body.
This part is a few hundreds dollars via eg eBay and can be diy replaced.
But obviously lookup your DTC codes n the FSM and do your own research.
