You need to have a pressure/flow test done on the system first, you may only have a certain area which is causing the problem. It sounds like the incorrect fluid has cause a seal to loose pressure in the steering rack.
Get it tested then you can have a better pin point on what is causing the problem.
Let me know if you need more information.

I have a 2006 chevy silverado with a 6.6 litre diesle that has what i think is a power steering fluid leak up at the master cylander or break booster on the fire wall the hoses run from the power steering...

The Duramax trucks by Chevy and GMC use Hydro-Boost brakes, meaning that they use a hydrolic pump for the brakes and the steering. GM has had real trouble with leaky Hydrlic hoses on all their trucks for a few years (like my truck) for leaking coolant lines from the trans and as I found out today during my oil change, coming from the hydro-boost. These are replacable, but not under warrenty for you or me.

Power steering went out on my 2005 chevy cobolt

NO FLUID. It's all electric, no hydrolics at all, do not try and find a place to put fluid into. You will need to get the codes out of the system to have an accuret diagnosis of what need's to be replace. The most common thing is the steering motor, but that may not be the case for your car. Report back with the codes in the system.

Both ATF and Power Steering Fluid are Hydrolic Fluids. They have different anti-wear and anti-foam qualities but it shouldn't damage the trans immediatly. I would definitly drop the fluid a few times and change the filter for peace of mind!!

2001 Chevrolet Tracker Steering Issues

i would check the power steering fluid level. if thats ok. then i would bet its your power steering pump. other possibilities although rare are :
if its power assisted rack and pinion, rack may need to be replaced if its damaged or corroded on the inside. or could be a pinched hose in the power steering hose routing. Wrong fluid in the power steering pump (causing the valves to swell shut) this happens when quick lube places put the wrong fluids in the wrong places. ( i went to one and they put the wrong fluid in my brakes and had to have my master cylinder replaced and brake system flushed... yes they denied it still cost me 350.00) also could be damaged suspension parts causing the resistance to your steering. hope this gives you some leads to find out whats up.

Loss of power steering in my 1996 Grand AM

What you've said is possible but likely there was some pump damage when you originally had the hose leak. Manufacturers have always said to use P/S fluid in steering pumps but within the past ten years this has become more critical to the point that I now would never "cheat" and use trans oil.
If you remove the return hose and drain system (running), then re-fill with p/s oil you MAY regain function, but it's not a 100% chance.
If you do this, make sure you bleed air out by turning wheels all the way left, then all way right and checking fluid level each time till oil level stablizes. If some performance is restored, repeat in about one week. If not, replace the pump.

1993 accord leaking a large quantitly of some fluid

Did u just get an oil change, or did they do anything else? Keep checking all the fluid levels, something has to get low enough to notice sooner or later. I noticed u didn't mention power steering, I assume your accord has it, did u check it? Also the radiator level. It could also be from a oil drain plug that is loose, or was put on too tight (which would strip the threads and leak) or a loose oil filter that wasn't properly tightened. So keep checking those fluids. There is a chain fast oil change place next door to where I work, and I am aware of some nightmare stories. So be careful where u go, there are good and bad garages, dealers, and oil change places. Check your local Better Business Bureau for a listing of complaints. A co-worker had the 4x4 transfer case cracked by over tightening the drain bolt. It was leaking pretty bad, and they were told to 'bring it in once a week, and we'll top it off'. Another co-worker had an oil change, drove home, his mother took his car out and the oil filter was not tightened, all the oil leaked out, and the engine seized. The shop swore up and down it wasn't their fault, and they just turned it over to there lawyers. 6 months later, the co-worker left for another job, and he hadn't collected a dime for his new $2k motor, or 10 days to rent a car. Let me know what happens, I'm guessing the shop is responsible, and you should have some one check the drain plug and oil filter asap to see if that's where the fluid on the ground is coming from. The location u describe is where the leak would be. countrycurt0
