I have done quite a bit of research on my two problems, will try to be brief but for me, it's hard, I have keyboard diarehea ROFL!
Please note that both issues started at the same time and both continue as of today.
Car: 07 2.5i wagon with 4eat, 42K, well maintained, complete UEL catless exhaust sytem, all other mods are suspension and appearance related.
#1 P0719 SUBARU - Torque Converter Brake Switch B Circuit Low:
After doing my homework, I'm gonna replace the brake switch, as of the past few days, the brake lights regardless of gear, only work when they feel like it. Most of the times, they don't work at all. Found this out fromt the wife when driving behind me from or to work, etc. So this seems to be the easy issue, if my diagnosis is correct. If I want to put the new brake switch in myself, how does one go about adjusting it correctly?
#2 "OIL AT TEMP" light flashes while driving:
Comes on randomly. If the car sits a bit and I go back out, it only comes back on when driving for about 15-20 minutes. Driving conditions are various.
Fluid changed at 30K, now at 42K, level is good, color is good, odor is good.
Coolant level good, car does not run hot at all (only say this cause on another board someone mentioned transmission cooler and coolant)
My thoery is this based on info I found in an inquiry by someone who had something similar on ask.com or one of those sites.
Theory: my brake switch is obviously toast, I have read that a faulty or bad brake switch can cause the tranny to act differently or shift differently as it's not sensing the brake pedal being depressed while slowing down.
Is it possible that the bad brake switch is causing the blinking "OIL AT TEMP" light while driving?
The coincidence of both starting at the same time, makes me think yes, but by no means am I an expert on these things.
So, I'm picking up a brake switch tomorrow and hope it's a simple 1 2 3 thing to replace eventhough I am not sure at what height to put it.
With regards to the OIL AT TEMP flashing light, which now happens every day, a few times a day, if I get lucky and it goes away, great, if not:
How do I proceed as the car still is under the 5 year 60K powertrain portion of the warranty.
The crazy thing, I call up my dealer and he say "$115" to diagnose the blinking light. I tell him and he agrees, that it's most likely tranny related and that if it is, I am under warranty for that. He says $115 and we'll go from their. What the hell is that all about???
So, I tried to keep my ramblings brief, what ya think, will I get lucky and the brake switch will solve the other issue, or do I have more serious concerns with the blinking "OIL AT TEMP" light?
I can honestly say, the car feels as good as day one, the only thing worth mentioning is that I think I can feel the car engine braking more than normal, if that makes any sense, which I thought as of tonight was related to the brake switch futzing up the tranny shifting a little.
Thanks for taking the time to read all this.
ps - if I am totally off of anything please let me know, I always help others on my local suby forum in NY and if someone else should run into these issues, I would love to be able to help them correctly
