Question about 2000 Oldsmobile Silhouette

Open Question

Transmission line flow direction for adding a cooler on a 2000 olds silhouette. I need to know which line is the one flowing to the transmission, or the return line to the transmission after it has already been cooled from the radiator. is it the top or bottom line? I have to install the cooler on the line that is going back to the transmission. Thanks in advance.

the light bulbs are not replacable unless you can solder, you have to replace the complete instrument cluster, get one from a junk yard 100 bucks.

Could easliy be your water pump. The coolant in the radiator isn't being forced through the engine by the water pump causing the coolant to be cool and motor overheating. A thermostat can also cause this problem, but I belive it's the water pump.

SOURCE: OBD inspection: 1 trouble code reported:P0401 EGR

Yes and know,it all depends on your experience with tools but you can do it if your follow instructions and take your time. I'll try to help you save some money and let you know that you can fix thins your self. 
A code P0401 most likely means one or more of the following has happened:

  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
  • There is a blockage in the egr (tube), most likely carbon buildup
  • The egr valve is faulty
  • The egr valve may not be opening due to a lack of vaccuum
So we are going to remove the egr valve and clean it out with Carb cleaner, remove all the carbon build up that is binding the valve. If that doesn't not work or you thing there is too much carbon or the valve it self is still binding once it's cleaned, then just replace it. The other thing to is to replace the DPFE sensor but were just going to worry about the egr first since that is what is most common and a good cleaning will always almost fix the problem. 
There is one bolt that holds the egr tube to it and two bolts that hold it to the intake manifold take them out, unplug the electrical connector and its off.  Once the egr is off, Spray it clean with Carb cleaner and make sure that there are no moving parts are binding and re-install. If needed replace the old gasket with a new one. Good luck and hope this helps and if your not sure where the egr valve is, it's just behind the throttle body. Good luck and hope this helps, Auto Zone can also give you the step by step instructions to getting the job done and you can also buy the replacement egr valve. But start with the cleaning first.

What is flow direction of transmission fluid adding a cooler

normally external coolers dont have a flow direction on them that I have ever seen.. you just mount it up front and attatch the lines and go...if there is a flow indicator(tho I cant imagine why) then I would see which line bleeds monentarily on startup and shutdown, and connect it accordingly...

Need to know which line goes where on tha radiatior comeing from transmission, need diagram showing hook-ups

They should only fit one way. Since this system is flow through they can hook up either way. If you have an external cooler the routing is simple. One line from trans to radiator, out of radiator to cooler, out of cooler back to trans. If no cooler, to rad and back to trams. As I said there is no specific direction.

I need to know which is the input flow and which is the output flow for transmission fluid


If you remove the lines off the transmission cooler and turn the engine over you will see which hose the fluid comes out of.
Then the other hose is your return hose to the transmission.

My 1999 Olds Intrigue, 3.5 motor, auto trans, heats up when going uphill. Going downhill, or on a flat road, with the same number of RPMs, it does not. Recently had the engine cooling system flushed, and...

could be a good candidate for the overheating problem
it is probably the oil line that goes to the oil cooler in the radiator and if it doesn't have sufficient flow then the oil in the transmission gets progressively hotter
before replacing it consider this
transmission oil coolers that are in the radiator tank keep the oil at coolant temps which is around 95 C
if you spend a bit of cash and fit an air to air transmission cooler , it brings the operating temp of the oil down to 1/2 ambient temp
besides the fact that your are now removing an added heat source from the coolant of the engine the results are --cooler running engine and cooler running transmission
worth talking to an accredited transmission specialist shop

My van is shifting hard at times and we changed the fluid and filter about 2 weeks ago and it was fine until this morning and it started again what could be the problem?

Check the fluid level first clarck the transmisson line loose at the radiator and make sure oil is flowing thru the cooler if it is then you have a problem that will have to be tested at a transmisson shop, there are to many thigs to list that would cause hard shifting but have it checked before you damage any interal parts because if you damage hard parts the fix gets more expensive.

How do i install a transmission oil cooler.

Can't give specific instructions for yours, but here are the general instructions: Connect the cooler to the line coming out (back to the transmission) from the radiator this way, the cooler does not have to do all the work. Use double clamps (ones made for fuel systems are best) on each end of the hoses, with the screws 180 degrees apart to avoid leaks. Hoses should be high pressure ones (about twice the thickness of fuel line) The cooler can be mounted in front of the A/C condenser...they sell mount brackets or you can use plastic pins that attach directly through the condenser fins. Make sure that lines are secure to avoid damage from vibration, and anywhere they must pass through a bulkhead, use a rubber grommet to avoid having the line becoming damaged from cut through by sharp metal. Don't allow lines to hang down underneath where they can snag on objects in the road. Likely the most difficult part is finding a good place for mounting, and getting to it.
Most coolers come with instructions. Good Luck!!

Transmission over heating

sounds like a plugged trans cooler.have it checked for proper flow should be less than 10-15psi if so it needs to be replaced. check to see if the trans cooler lines go into the radiator. if so you will either have to replace the radiator (trans cooler is part of radiator) or buy and install an aftermarket cooler
