[quote name=NorthWet Nipper: Do we KNOW that the TCU looks for an EMF buck when it actuates, as opposed to just looking for a certain impedance? If so, that would be nice to know. [/quote] We know from two sources. One is from people experimenting with a switch to force AWD. The other (and not so clear) is from all the 4eat literiture from Subaru. They state the ecu for the tranny will flash the light for an open or shorted solenoid, solenoid failure to move (stuck), and the solenoid bieng stuck fully closed or fully open. nipper

this is why you need somone who knows suabrus. That noise they heard was probably regular subaru engine noises. Change the knock sensor. Do not take the trannies shop word for if they say you need a new tranny. if the tranny is not slipping its working fine. nipper

re read what i said, the solenoid can be in the process of failing too, an intermittent electrical problem. You will get a tranny temp light if the puter sends power to the solenoid, and does not see the voltage spike that tells the puter the solenoid valve has moved. you wont get a FWD light for the same reason. You wont get the light if the solenoid is burned out or stuck in the closed position. nipper

thats why i pay the big bucks to get the magazine

Well technically it is reverse flow. The thermostat is on the botom of the engine. The coolant flows out of the bottom of the engine, across the radiator into the top. That hole in the the tstat is important and you need to use an oe tstat, radiator cap can be anyones. nipper

your fogetting a few things. Electrical problems can be intermittenet. ALso just because the solenoid is receiving power does not mean the valve part of the solenoid is moving, it can be stuck. and yes they are wired backwards, why that was done i have no idea, usually you have to power a solenoid to turn something on, not the other way around. nipper

where you mounting the gauge sensor? nipper

no its not that simple, you need bigger injectors, a scrubbed fuel system, and a reprogramed ecu to name a few. Also while e85 seems cheaper it gets 30-40% less mpg so its a wash. nipper

water pump will go with age. Sounds like you have an air buble in the cooling system. nipper

you need to know where this is. If you ever put the spare on the car you need to put the FWD fuse in the holder. It disables the AWD by holding the duty c solenoid fully open. nipper

headgasket i dont know what came first, but thats a headgasket. nipper

ok if you have heat we can rule out an air bubble, and i almost want to rule out the HG. Usually a blown HG you have no heat. Where did this radiator come from, and have you done a flow test on it, or at the very least felt the radiator hoses. Does the car overheat with the cap off. If the car pushes out fluid with cap off (after the tsat opens) then you have a hg issue. tsat should be an oe tstat. The thing is, its possible the HG did not cause the first overheat, but if the car got so hot for it to stall, chances are now you have a blown HG. nipper

no. Once the duty c solenoid fails the damage happens quickly. You may be lucky, as i have seen a few dealers just replace the solenoid, hard to tell with your low mileage. Ask them how they determined its both. nipper

when was the raditor changed? what was the reason for the engine swap? DOnt jump to conclusions just yet, any boil over can cause water to come out of the cooling system. Also when the tstat was repalced, are you sure the air bubbles were removed from the cooling system. Usually you get no heat with a bad HG, and you said you had heat. nipper

sheesh there is a universal joint on either side of the bearing. The bearing is located in a rubber mount, then is in a barcket that bolts to the car. i dont remeber the3 original post, but be prepared for the ever popular torque bind nipper

go by belt tension. 1/4" of play is perfect. this is the only good way to tighten a belt. nipper

ah grasshopper, everyone is quick to apply heat, but no one applies cold. Try sticking it in the freezer first and see what happens. nipper

the clutch pack is designed to tolerate some slip. there is no viscous coupling. The amount of torque split is controled by the cycling of the solenoid and an internal spool valve. ive been here done this wrote the 950.00 check. good luck nipper

fluid change and a cooler. Modern trannies arent like older ones, they arent affected by sudden work after a life of leasure. But with trailer towing do change your fluid every year. nipper

Subaru trannies the torque converter locks in all gears. Did you ever have the knock sensor replaced. The knock sensor adjusts timing and can do ver wierd things. Those weird things can translate into a confused tranny and poor shifting. knock and piston slap are two toally differnt things. Some things can not be ignored, this is one of them. Pay attention to your cel. Also you can shift the tranny on the fly on any automatic car. There is no need to pull over (read any owners manual, they have been like that since the dawn of the auto tranny). You need ot learn how to use the tranny properly, its part of being a smart driver (especially in hilly areas). If there are a lot of hills ill put my car in drive 3 to give the car a break. This stops the hunting. nipper

First thing to do is not go back to that dealer (unless its under warrenty). Sounds like they didnt bother pulling the codes. Go to an autozine and let them pull the codes. Modern cars dont have many fuel system issues, so this is going to be electrical. It can be the coil, the ignitor, or bad cam/crank sesnors... or a few other possabilities. SInce it doesnt do it when cold, im betting on an eletrical issue. We need the codes. nipper

Autozone will pull codes for free. You dont say the mileage (GRRRRRRRRR) or if the waterpump was ever replaced. Possabilities: Water pump impeller failure due to mechanical failure or erosion of the blades Clogged radiator (simple flow test with a gardehose will confirm) Bad timing belt tensioner (allowing the belt to just pull over the waterpump and not turn it and the ever popular (but rare on a 2.2) head gasket. You can get a Hydrocarbon test kit from an autoparts store to test for exhaust gasses in the coolant. The fact that the car was hot enough to stall means you need to do an oilchange asap. The oil has gotten cooked and the last connecting rod bearing will fail under these circumstances. SO the 10.00 question, when was the last timing belt change, and what was done when it was changed. nipper

cool give me an email nipper

this is why im completly stupid, if somone can do that for me ild gladly email the articles (btw it also sasy they are dedicated to building a deisel) nipper

This si from SAE mag, dont know how well it will post, but it explains what Sooby is up to (i am never sure if i do this picture thing right)
