Trying to flush the transmission and power steering on my 92 pickup without having to pay the 40 bucks at service center
I looked at the tranny and see two different plugs. assuming ones a drain and ones a filler, but have no idea which is which. Also where is the filter located at so I can clean it out

Far as the power steering, I don't even no where to start. haha

Any advice is appreciated

Manual trans??
A power steering flush is pointless honestly imho.

bman120

no automatic

why do you think it's pointless?

Rerunn

Pretty steering components are not that picky on how clean they need to be. I mean don't put junk fluid in it but it's pretty much low maintenance.
As for "flushing" the trans I'd simply do a drain and fill. You CANNOT do a full flush without proper equipment and in more cases than a few I've seen transmission flushes do more harm than good.

Alright, wheres the filter at? I'd still be able to clean that out right?

Rerunn

I'm not 100% on those transmissions having a serviceable filter or not. But yes you would replace it.

alright. maybe i should just take it in so they can flush it.
It seems to be vibrating a lot when I'm stopped and in gear. Almost like I'm idling too low but as soon as I put it in park or neutral the rpms shoot back up. I don't have a tachometer so I can't really tell wheres its in gear, but I thought the fluid was old and maybe thats why

Hi
on my auto i did a passive flush. drain two litres of auto fluid add two litres of fresh fluid. Drain 2 litres every 1000 miles until fluid is red.used dexron 6 which has cleaning agent in it. and is alot thinner in cold temps takes more sbuse ie withstand high temps without breaking down.what a difference.

The auto tranny fills through the dipstick tube. Typically, the tranny drain plug is on the bottom of the pan. Not sure what plugs you are seeing unless it's the ones on the transfer case. Pics?

On the auto tranny, there is a metal screen filter attached to the valve body which is exposed once the tranny pan is dropped.

The screen can be cleaned brake cleaner or carb cleaner. I then rinse it with fresh ATF fluid to remove traces of solvent before re-installing.

Tried cleaning the throttle body?

I may just try the passive flush. It'll take a little more time but sounds pretty easy.

Yeah I was definitely looking at the transfer my bad. haha
as far as the screen filter, how hard is it to take off the tranny pan? as you can tell I haven't had a lot of experience with doing this stuff myself, but I am wanting to learn real bad. haha

Honestly have no idea how to clean the throttle body. haha explain please?

Get under and take the bolts off (you might need new seal) careful on taking off the pan after the bolts are off. (Clean the pan too while your at it) remove the filter two or three bolts, then bolt on new filter (or old cleaned out one). Then redo the seal and bolt the pan back up. alot of steps but really easy, just pain in the neck when putting the pan back on. Have fUn

sweet thanks. Any ideas for the vibrating/low idle issue I mentioned earlier?

You can clean the oil strainer, but they're only about $10 at RockAuto. I'd just replace it.

Cleaning the throttle body will cure that.
Pick up some throttle body cleaner at a auto store. Remove the intake tube and look in the throttle body and you'll see all kinds of black gunk. Clean that out with a rag or a toothbrush works best.

Alright thanks I'll give that a shot

Power steering fluid whether it's Dexron or regular power steering (hydraulic) fluid, needs to be changed just like any other fluid as it gets dirty from wear in the system and needs to changed out. To describe it simply, have another person with you and do this:

- empty old fluid out of reservoir and fill up with new stuff

- remove the return line (soft rubber line) from reservoir and run it to a container; you must plug the return line nipple on reservoir

- start truck and as you slowly turn the wheels back and forth, have your buddy slowly pour fluid into reservoir to replace the fluid coming out of the line into container (do not let reservoir run dry)

- when the fluid coming out of the return line into the container is clean, your system has been flushed

- reattach return line to reservoir and check fluid level.

Your system has been now flushed. Very easy job.

If you wish to add filtration, you can use this filter. I have used it before on my Ford plow truck for the steering system. They also sell them on Ebay. I rebuilt my power steering pump for my 94 and will be using one on the return line. I bought a 1/2" filter and bought brass adapters because the return line in our trucks is about 5/8". You will need 5/8" to 1/2" adapters. Hope this helps.
