  1. well they have too. The FWD fuse sends a signal to the TCU to power the duty c (hold it open) so the AWD is disabled. In order to get AWD on demand, you need to interupt that circuit between the TCU and the solenoid. The rest of your argument is valid. nipper
  2. your close. Not only does the duty c regulate the application, but the spool valve regulates how much force is applied to the clutch pack. Example: The duty C (easy numbers) pulses 30 times in 60 seocnds to give you 50/50 split. The spool vlave regulates how much force is applied to those clutches depending upon line pressure. I am not sure if this is an inverse relationship. This would be a function of engine RPM, as the engine drives the pump. The digram ive seen is not really clear on this function. This function mechnaical (hydraulic) and not electrical. It operates in cunjunction with the Duty C. There may ebven be a balancing act, since the duty C is more directly related to this spool valve then the clutch pack itself. The bleed off of the Duty C is probably the magic potion thats missing to make a switch work. The FWD fuse is just a signal to the ECU. nipper
  3. SHameless plug .... hehehe but i buy from Jamie when i need an OE part nipper
  4. word to the wise, almost everyone that seems to put this switch in within a year blows thier clutchpack. There is more to the AWD unit aside from the duty C solenoid. There is also an internal spool valve that plays a part in this. That is controled by the duty c and internal tranny pressure. i strongly dont recomend this switch. The switch will trigger the tranny temp light on the next start. Why do you want this switch anyway? the TCU does a very good job at operating the awd. nipper
  5. Get a haynes manual, it explains it fully. The VSS sensor is a hall effect type. It pulses on and off as the square tooth gear passes it. Without the VSS sensor you have no AWD, poor performance, along with a bunch of other things. The dummying of the VSS has me very worried. There is no reason in the world why that other mechanic should not have replaced the sensor. It takes longer to dummy it then to replace it. i hope he didnt damage anything. The VSS sensor doesnt trigger anything on the AWD. It gives a speed signal to the tranny puter, and along with other inputs, the TCU decides what to do. This is also true for shift points. Some people (pm) should not be allowed near tools. i bet the car has a few other issues too, as the bad VSS should throw a CEL. Does your CEL come on when you turn the car on? nipper
  6. They are all overe here in oregon and washington. In Montanna vehical of choice was a full sized p'up. nipper
  7. Low mileage cars are NOT the dreams they portend to be. Especially if somone changed the oil by mileage and not by calender. i would trust a car with close to normal mileag way before i would trust one with low mileage. i am not surprised you lost a conn rod bearing. nipper
  8. First off AMACO is full of BS. They are the biggest rip off this side of the spray on hair commercials. First qyestion is how did they determine there was metal in the pan? did they drop the pan? Did they test drive the car with pressure gauges on it. Second, if the cars only problem was TB and it was shifting fine then there is nothing worng with the tranny. Get a flush at a jiffy lube, or do it yourself. Its a 99.00 gamble vs a rebuilt tranny. MAN AMMACO PISSES ME OFF i dont even know where to start, so ill try to calm down. i have a poor connection so cant read what everyone else said. make sure the tires match. Material in the bottom of the pan is NORMAL. If the car is shifting fine, then you may just need a clutchpack at 800-1000 bucks. Take the car to a dealer and let them look at it. Used tranies you run a gamble on them having TB also, but the awd section of the tranny can be replaced all on its own. nipper
  9. look it up and open a case of beer and read. That and Head gaskets can go on for pages nipper
  10. 30 minutes will do it, though most will let it go overnight. i hope your not like me where you have to spend 20 minutes resetting the stero grrrrr nipper
  11. GRRR 10-15% of production does not make it notorious. As with any aluminum engine regularly change coolant and dont let it over heat. Change the trany fluid if an automatic to avoid torque bind. not alot you can do for perfomance or mileage. They are reliable cars but a bit boring, though i like my 2.5L nipper
  12. do a search. The gas gauges get contaminated over the years and become innacurate. Techron or Chevron ( i think) has an additive that cleans the gauge. nipper
  13. lowest 1.99, highest 2.99 avg 2.40. Gas got higher as i got west. 2.99 was black hills/Mt Rushmore (avg 25 mpg) nipper
  14. gee i already did the nickle tour of Montana (dont you guys have any roads that DONT lead to Alberta?), Glacier Nat Park nipper
  15. replace the sensor first and see what happens. a bad sensor will give you a bad cat fault, and may not be true. nipper
  16. thats not how it works. There is no shifting of power, just sharing it. You get between 90/10 to 50/50 split. The 50/50 is in low and reverse. The newer versions plays with the brakes to transfer more power to the non slipping wheel, basically you can do the same thing in an older one by slightly applying the brake (or on a manual by applying the hand brake). It doesnt decide to dissconnect power fropm the front and send it to the rear, or visa versa. The front wheels basically propel the car. If the front wheels spin faster then rear, then power is applied to the rear. There is almost no way for the rear wheels to spin since the car is biased toward the front. Now if if the car was biased towards the rear, then if the rears spun, power would be applied to the fron untill everything was spinning the same speed. nipper
  17. sorry thats TWO beers and a shot. The thought did cross my mind, but my lawyer called today and i have to be home the end of october. nipper
  18. nope just ol Blu, 193,000 miles on her now, and next will either be seattle or SF nipper
  19. Check the busings, motor mounts, frame and wheel bearings along with calipers. nipper
  20. Back when i was a kid we didnt have no fancy zip ties, it was bumper stickers and chicken wire hehehe nipper
  21. so subarus use yorque converters and american junk use troque converters... yuppin yimmity nipper
