Secondary speed sensor

Call Subaru with the last eight of your VIN number to get a part number.

Thank you! I started following you as I am doing most of my own work on this car. We are at 400k miles and counting!! Right now I am getting P0700 and P2750 codes with dashlights on... but the transmission shifts fine. Paddles do not work. Cruise does not come on and it is basically front drive only. There is a shudder but i did not do a relearn on it when i put the rebuilt VB in. I am doing the relearn this afternoon. I'll let you know if any progress. Any other thoughts at this time?

 

Wow! Let’s observe the fact that we have an FB and 580 at 400k miles! Congrats!

 

Why are you surprised? It's a Subaru.

 

Update: Found a new Error code with the new XTool D7 OBD2 scanner in the Transmission module. It shows a P0971 which is the Pressure Sensor solenoid in the Valve Body from what i have read. I replaced the TC Solenoid already and it is still doing fine. Guess I should have done them all while I was in there last time like others have suggested on here. I'll replace all remaining Solenoids, reinstall the VB and do a relearn over the next couple days. I'll update on status once i finish.

 

Update on the "rumble" issue on acceleration that I have been working on the past few months... So after having tested and replaced two bad solenoids in the Valve Body and then doing a full relearn, some nice gains were made and the rumble issue has been reduced by about 75% but is not yet eliminated. So this weekend on the advice of a local backyard mechanic i went ahead and replaced my driver side CV Axles which had started making a little noise... and voila! the rumble has now 99% disappeared!!

 

So it seemed like replacing the solenoids was the fix for the p2750 code? Currently trying to track this down - it's not yet bad enough, and kind of intermittent, so it's really difficult to diagnose. I was looking at the secondary pulley speed sensor, but I find it highly unlikely that's bad and more than likely it is working correctly and just telling me there's an expected pulley speed mismatch.

Currently having what seems like slipping at random times when cold/slow speed. I had it happen once at highway speed. And the previous owner sold it to me for almost nothing because Subaru said it needed a new trans...43k miles ago.

So far diagnostics haven't shown a bad solenoid and the only indicator I have at this point is the sensor after following diag procedure for the code.

 

Look at the Primary Pulley speed. When the belt slips, that's the one it slips on. Any slip is rebuild or replace.

 

Ugh, I don't have anything to diagnose with as it's been driving fine for the last 2 days/~200 miles...I hate intermittent problems. Thanks for the feedback though.
