Does anyone know what psi the fluid comes out of an AOD for the cooler. And second i am thinking with the rack and pinion that i have being so easy to steer without a pump can i run a line from the trans into a cooler then from cooler to the pressure side of the rack and pinion out the return side through a filter then back into the trans. Seeing as auto trans fluid and power steering fluid are very similar in makeup the rack should be able to handle it. Just dont know if the psi comming out of the trans will hurt the rack. And it would eliminate using a pump. And if this works would it be a good idea to run a crossover tube from the pressure side to the return side of the rack. My thinking is this would keep fluid in the rack and keep fluid going back to the trans. Am i crazy for thinking or no let me have it.

Dont judge me, you dont know my situation.

I don't know AOD, but all the other trans I'm familiar with have nowhere near enough pressure to actuate power steering.  I don't think it is a good idea.

From memory the testing PSI for setting the TV cable on an AOD is less than 150 psi. power steering needs 1000psi to 1500psi depending on the unit. If it doesn't exist in conventional cars then don't do it.

I am not looking to get power assist i am just looking to keep fluid in the rack as the steering is about where i want it without any pump hooked up. As for "if it doesnt exist in conventional cars dont do it" alot of ideas in conventional cars didnt exist when they were invented. I am just trying to think outside the box a little.

Dont judge me, you dont know my situation.

I agree with the others and also would say I wouldn't be messing around with the AOD and it's cooling OR pressure situation. JMHO.



BUT all that said if you're are willing to risk loosing the trans over it then why not be the first to investigate it. I wouldn't risk mine.



btw, the aod potentialy increases engine & radiator temp as much as the radiator and trans cooler lower them back down. So it's a balancing act. THe AOD won't tolerate heat OR cold.

I wonder how the trans cooler works on an AOD. I know from some experience that the internal pressures are critical to proper operation and even survival. But do the cooling lines run from the same area? It would seem not. I would think the lines to and from the cooler would be a risk of pressure variation. Just wondering? Chuck

from what I understand he has added a rack and pinion from a donor. He has gone from 20:1 to 16:1 (ish) and now has steering which is too light to need power assist. Something has to be up for this reduction in mechanical assistance to reduce the effort needed to turn the wheel.

Steering geometry needs to be considered before adding just any rack, off any car. This car could be really dangerous especially if his attitude has carried over.

Steering geometry is correct. Made many many measurements and fitments. Its the same rack as the aftermarket kit just i had to make the brackets.

Dont judge me, you dont know my situation.

And no attitude here, just didnt think i was getting my question across with the responses i recieved.

Dont judge me, you dont know my situation.

Can't help on the AOD, but I've got a Cavalier power rack, the "quick one", and early style Saginaw pump, and a hydro boost brake unit (probably early Cutlass diesel). It all works fine, but in retrospect, I should have stayed with the ford pump, or gone to a later style GM or Ford pump, which operate on lower pressure. I was misinformed by an "expert". Heidt's sells a bypass valve that goes into both the pressure and return line, and lets you dial down to whatever level of boost you like. The return side is hose clamps, but the pressure side requires proper flared lines/hoses. Some of which may mix metric with SAE fittings, or different flare angles. It's main application is an old pump like mine, on an early Mustang rack. Apparently, all the later models use lower pressure. It stops the "twitchy" feel from too much boost. At least in my app.
