Ha! That's good stuff. Looks like I need to grow a stache now! I've got enough work to do on my own vehicles to even mess with the neighbors. I wouldn't trust myself to rebuild any transmission except my own! I checked the fluids in the Sierra the other day. I've put around 1500-1800 miles on it since I've owned it. It was a quart low on oil. I climbed under it and it looks to be coming from the upper rear of the engine. It almost looks like it's coming where the tranny and engine meet. Rear main seal? If so, I figure I might as well rebuild the tranny if I have it out. I would think it would cost less than $100 since everything should be in good working order. That hard shift into 2nd bugs me. Nick mailed me a rebuild dvd for the 4L60E. The plan was to just to the shift kit that is suppose to help that shift. I planned on doing that so I wouldn't have to pull the tranny but that was before I noticed the oil leak. If you had to pull it for the rear main seal would you rebuild it?
I once thought the power steering system was a piece of cake but this one's being a pain though. It should be fine once I fix the bend in the hose and especially if I replace the new pressure line I installed with another new pressure line. I now know for a fact that it's leaking where it hooks to the steering rack. It's plenty tight too so maybe it is just faulty. I guess we'll find out tomorrow. Out of the whole job this part has given me the most grief.

Well, replaced the new pressure line with another new pressure line and that stopped the leak. I also replaced the small rubber hose on the return line. There are no leaks but it's still making the whining noise. I'm thinking I might've burned the pump up when I took it for a drive yesterday. Going to try a new pump and see what happens. I'm pretty confident it's the pump but if that doesn't do it I have no idea and will be starting a new thread on it. Have to take the wife out so going to get a pump this evening. After getting a Christmas tree tomorrow I'll swap it out and let you know.
I took it for a 5 mile drive a little bit ago and the tranny is smoooooth! Sorry, I had to mention it again!

Hmmm? We continue with this PS issue. Can't be ignored of course. Pump itself may now be bad or was bad. Now I worry if old one or new one has thrown debris? Could end up playing ping pong fixing one problem but fail if two aren't done. Not real sure of the best approach but would be checking fluid captured thru a coffee filter or something to get an idea.
Some pics of both that state OE exact?..............
Pressure one........
Return one...........
That extra loop is to cool the fluid but more often get damaged or rusts where they place them so far with ones that came my way.
Never used but see it available is a filter not used TMK for OEM. See if a pic shows.......
Has to be on return line by looks. I plead that I have no clue if it could help or be just another place to leak or make lines rub??
Bleeding instruction didn't say anything out of control. Just front wheels up and steer stop to stop many times watching fluid level basically. That info could be all wet?
I worry about the rack now if it is damaged or was failing in some way or not passing fluid thru it. Help guys - how would you test or approach that? Another whole brand of vehicle was known to me to just have those fail like clockwork probably catching too much exhaust heat? - T

A filter is a good idea. On the return line there are two spots where you have to attach a section of rubber hose. There's the spot up top by the pump which a filter wouldn't work there. There is then another spot on the right hand side by the half shaft. There's plenty of room there to put a filter.
I really think that the new pump burned up from the small section of u shaped hose being squashed flat. I replaced that hose with one that had a molded bend so it's fine now. I'm almost positive it's the pump. If not, like you said, maybe it's the steering rack. When removing the tranny it says to wire the rack out of the way. Maybe from being old and with it hanging caused some sort of damage.
I have some things to do today so will be doing the pump later on. If the new pump doesn't do it I'm going to start a new thread because I'll definitely be at a loss. I have high hopes with the new pump though.

I'm worried about the pump really being the source problem again or not. Do remans just get a wash and wrap + paint up job out there - I know so and avoid that brand again if caught. For PS how long is enough to harm one? Not sure.
Does it have power assist feeling normal even with the noise? I really don't know the best way to test for proper pressure ability and volume of return fluid to be sure of the fix.
Arggh - I think I'd see with it running and helper putting some turning force on it now if return line quickly removed could push back out fluid such that plain no return or VERY poor return flow was an issue.
Dang MG - you've come up with some real brain teasers. Can happen but what if another reman pump does the same thing? It's happened with assorted reman things but sure causes one think they have the wrong diagnosis or doing something wrong to me anyway. Gotta do something no matter what and don't know any good solid known ways to know for sure how to be sure, - T

The other day it did have the power steering assist feeling when I took it for a drive. About a mile in it got worse though.
I got the new pump on. I'm still not sure if it's quite right. It has taken awhile to get the air out. I don't think it's all out yet though. Either that or it has a very small leak somewhere. The more I turned the wheel the better it has gotten. I can turn the wheel all the way and I don't hear any whining. But, if I really crank on the wheel it will whine. It took about 20-30 minutes to get it to the point where I could turn the wheel all the way and it wouldn't whine. That's why I kind of think it's getting there. I have never had one take this long to bleed though. That's why I'm wondering if there's a tiny leak. Is it possible for air to get into the system without leaking fluid?
Since it seems like I've gotten 99% of the air out I might throw the tires on it and take it for a spin sometime tomorrow. I'll probably just go around the block a few times so I'm close to home if I notice a problem.
I did notice the radiator fans aren't coming on. Looks like something else to look into.
Also, I mentioned somewhere along the way about the oil leak on the right hand side of the engine. Replaced crankshaft seal thinking that was it but was still leaking. I then figured it was ps fluid. Well, I'm not so sure now. I can get underneath and look at the ps fittings and they are not leaking. I still have a tiny drip in that same spot. It looks like it may be coming from the head gasket. But, if it was the head gasket, wouldn't it be leaking coolant and not oil? It seems to be coming from the back right corner of the head although I guess it's possible it could be running down from somewhere. It doesn't look like it though. The thing is, when I did the intake I replaced all gaskets above the head. I know that doesn't mean anything though. I'll have to try and get a better look somehow. It's a slow enough leak I'm going to worry about that one until later.
Hopefully tomorrow the ps will end up being okay. If not, what the heck else could it be? I did have both lines off and had to reseal a plug on the bottom of the rack so I'm sure there was plenty of air in there. I wouldn't think it would take as long as it has to bleed it though. Maybe the whole issue all along was just air? Out of this whole tranny job I never though it would be the ps system giving me such grief.

Quote">>Is it possible for air to get into the system without leaking fluid?<<"
? - No in this case and IMO. PS = hydraulic pressure and return. Reservoir is just there not pressurized as they will run with a typicel set up with cap off just could splash some out.
Notes: A key property of PS fluid, hydraulic fluid and ATF is the "antifoam" properties. Shoot me if wrong but I can't think of where in a PS system there would be vacuum to make vapor. At best perhaps flow thru a restriction could make the 'Venturi' effect and vapor (air) that you wouldn't see.
*If bleeding has been a real pest there's nothing I've found out there for tricks or special ways for this. Once wheels on ground and steering you are then asking for real pump pressures to work, off ground they aren't pumping that hard. Note the harder you turn the harder it works like being in the shopping center and the idiot trying to squeeze into a spot too tight has two arms and a leg turning wheel against the stops and wonders why a hose exploded

YES! Definite chance there just never came my way and wasn't thinking the remote reservoir. Had to look so will show what it should look like for the record......
Hose and clamps not shown so if the freaking tank itself is OK do the dang hose. Guess - 10mm fuel injection/PCV hose but make sure. This is where the freaking quality of clamps counts yet again. I would hunt the earth over not to use plain cheapo clamps but ones known for a full circle grip. No goo just right stuff.
I can't know how long a pump can buzz away without trouble as I'm not in cars that do that or would scream as a passenger to tend to it. Did have a parts car still running around this joint for a couple years with a wild PS leak but had to move it now and then. Just filled it and was fine but once too many and it did fry the pump that I wasn't keeping off of the thing anyway. A Ford pretty standard pump and took quite a while before that one did ruin itself.
Back to this: Is any evidence of leaking with anything about this, that hose showing OR anywhere another leak you were having trouble finding exactly where it was from? T

I purchased a new pump. It came with the o-ring for the reservoir in a plastic package with direction on how to install it. The pump I purchased came with the reservoir attached. I didn't pull the reservoir off to put the o-ring on because I assumed that the instructions and o-ring are thrown in every box including if you only purchased a reservoir. Should I have pulled the reservoir off and installed the o-ring? I've done others in the past and have never had to do that. I'm thinking they just package all of them like that just to save time and confusion?
I just don't see them assembling the pump and reservoir and not installing the o-ring. I can see if they forgot but I'm on my second pump in two days.
I haven't messed with it yet today but am going to check it out here soon. Have to get the Christmas decorations out of the attic first.

I not sure if I missed this...but is the fluid foamy while the pump is operating?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

I checked the fluid quite a bit last night and it was not foamy at all.
It seems to be getting better the more I turn the wheel. Right when I started the van up about 10 minutes ago I could hear the power steering pump. I then turned the wheel back and forth about 10 times and it's much better. I can barely here the whining noise when I turn it all the way. I'm thinking it's not bled all the way. It sure has taken a long time though. When I pull the ps cap off I can here the pop of suction which I wouldn't think I'd be able to hear if it was leaking somewhere. Well, I guess if air is getting it and not out it could still do that, correct?
I think I may have to hold off on the ps anyways. A few minutes ago I was looking for fluid leaks. Remember me saying that it looks like there's a leak on the back right of the engine? Well, I can see slight bubbling coming from the head gasket.
When I finished up the intake there were times the temp gauge would creep a tad over halfway which it normally doesn't do. I figured it was air in the system and continued to bleed it. I then noticed the lower radiator hose had some drops coming out of it where it connects to the engine so figured that was it. It wasn't much longer the tranny went. I put the new hose on the other day. When I started the van to check fluid levels vents weren't blowing hot even though the engine was warm. I bled the air out of the cooling system and topped off the coolant. The next time I started it everything seemed fine. Last night was the first time it looked like it was going to overheat. I did notice the radiator fans weren't kicking on so figured that was the problem. I'm 100% sure I'm seeing the bubbles out of the head gasket though.
What do you guys think about this. Screw the ps for now and do the head gasket. I'll have to bleed the ps system again anyways if I do the head. After this there shouldn't be a damn thing this van needs. Well, except for a for sale sign.
Ha, and you guys though you were getting rid of me after this tranny.
