removal of the valve body

Hi,

I did build a kind of a sandwich construction consisting of two pieces of plywood. I unscrewed the 3 screws holding the cover down. Then I relieved the screws of the sandwich and I could see what is really pressing against the plate. Actually, just two springs really did press against the cover plate. Relieving the pressure on those springs I could take the cover off. Then I had a hard time to get off the gasket because the gasket was extremely stiff and sticked to the valve body. I used a carpet type of blade to remove all traces of the old gasket and using a flashlight I removed all the remnants of the gasket in the cavities. I cleaned every spot of the valve body. I also took out all the parts behind the solenoid and I cleaned them. I had the feeling that the parts behind the solenoid were kind of stuck. Thus, I took them out and cleaned them. Now they are moving easily when pushing with a screwdriver.
I cleaned all the balls and the cavities the balls were located in. I checked every part of this valve body for remnants of the old gasket. I guess I took everything out. Tomorrow I will put the cover on again and then I will put the valve body back into the car.
I have put up 2 pictures on the internet. In case you are interested in looking at them you will find them on the website www. neuro-concepts.com/Ford- Explorer/Cover.JPG and Ford-Explorer/Sandwich.JPG. The guy who is doing my website work told me that the spelling is extremely important and that especially the small font and the capital font have to be considered.

I asked a Ford specialist what kind of torque value I should use to screw the valve body back into the transmission. He didn't know. He simply said: Not too much and not to little. I guess that 30 inch pounds will be sufficient.
In case you would like to get some more pictures simply write me what you would like to get and I am going to make the pics.
Your advice was really very helpful otherwise I would not have dared to attack this task.
Greetings

removal of the valve body

Hi,

according to your table I should apply around 80 inch pounds to the screws holding the valve body to the transmission; actually, I hadn't mentioned that before; at the time I unscrewed the valve body my feeling was that most of the screws were loose. I didn't take very much force to loosen them. Maybe that played a role in this problem.

Wulf

Loose valve body bolts create problems. The gaskets start to leak, then you lose hydraulic pressure. The electronic transmissions with an EPC solenoid have more of a problem with loose bolts since the EPC resonates under 300 HZ, and causes the bolts to get loose starting in the area around the EPC. The bores wear out faster too.

removal of the valve body

Hi,

in this context; at the time I ordered the gasket the Ford guy told me that I cannot get 1 gasket. I had to order the package and the package contains 3 of the gaskets. I didn't mind because the price per gasket was just $ 6; however taking the cover off the valve I realized that I needed at least two of those gaskets. Now my question is: What s the 3rd one for?

Anyway, I guess that all those issues contributed to the malfunction of the transmission. I really hope that now the problems are gone and the transmission works fine.
By the way, how many quarts of transmiission fluid would you recommend to put into the transmission? The guy at NAPA recommended to put in 6 quarts. I guess that is too much. The last time I put in 5 quarts and even that was a little bit too much.

Greetings,
Wulf

You have a lower & upper gasket (no 3d gasket) with 2 thickness options. The regular thickness is Ok for new valve bodies, and a slightly thicker one for older valve bodies that might be slightly irregular or warped. Either way, the thicker one should last longer, and is only about a dollar more in cost. These gaskets are a few dollars each, and shouldn't cost as much as what he charged. Find out if he gave you a lower & upper gasket, and the thickness.

removal of the valve body

Hi,

I actually ordered one gasket - not knowing that I would need two gaskets. Some hours later I got a call from the guy at Ford. He told me that he can only get a set of three gaskets each running $ 6. I ordered the set. It is called E8RY-7D100-A.

replacement of the TCC solenoid

Hi,

first of all I would really like to appreciate very much your help in conducting this task. Without your support I would not have touched that valve body.

I am in a kind of a hurry as far as the repair of this car is concerned. First, I used the shop of one of our neighbors to do that and I don't want to bother them more than necessary. Second, I need the car in the upcoming week.
Therefore, I put in the gaskets delivered by Ford. I used the torque values given in your table: Valve body 80 inch pounds and 120 for the pan.

I poured 4 quarts of transmission fluid in. The mark on the fluid level indicator is above the hatched area.

Once again thanks for your help. I will start the car in the afternoon because the exit of the shop is blocked by a car of our neighbor.

Greetings,
Wulf

Let us know how it works once it's finished. Was the gasket the regular one or the thick one?

Replacing TCC solenoid in 92 Explorer XLT

Hi,

all three gaskets were of the same thickness; therefore, I took two of them to do the job.
As I mentioned before the screws holding the valve body to the base were loose and the gaskets were very brittle. Actually, I was a little bit afraid to use the torque of 80 inch pounds. Therefore, I started with 60 inch pounds. After having done that to all screws I increased the torque to 80.

It is just a couple of minutes ago that I started the car and did my first short drive. It feels OK. I was just going up to 25 m/h and there was no problem at all.
Tomorrow I will do a real test ride. Before I do that I need to check the level of the transmission fluid. I put in 4 quarts and I know from the filter exchange that I filled in more than 5 quarts relying on the info given by the NAPA guy. I guess that I have to fill in at least another quart.
I imagine that you know the exact amount of fluid to put in. Thus, I will rely on your recommendation.
Of course, I will keep you informed about the result of this repair.

And once again thanks for your help

Greetings,
Wulf

The deep 4 X 4 pan uses 3 quarts, so start with 3, then add accordingly. The upper & lower gaskets are different. I hope that you didn't use the same one for both.

Replacing TCC solenoid in 92 Explorer XLT

Hi,

I did use the same type of gasket for both sides of the cover plate.
What can go wrong?
If there is really a problem with the gaskets it will now (after having the experience) no problem in taking the valve body apart again to replace the gaskets with the correct ones.

Hi,

What will be the consequence?
Greetings

[BrooklynBay]

The lower one is missing the gasket in the servo area, so part of it won't have a piece of gasket. Are you experiencing a delay shifting into reverse or manual 1st gear?

Replacing TCC solenoid in 92 Explorer XLT

Hi,

I cannot really say anything about the performance of the car after having done this repair. The ride I did was simply too short and the speed too slow.

I will drive the car tomorrow and I will check the level of the transmoission fluid once the car is at operating temperature.
I will then write my opinion about the situation.

Greetings,
Wulf

I drove the car this morning. There was the delay you were mentioning in your thread. I drove the car for 5 miles or so and then I stopped it. I checked the transmission fluid level and it was low. Thus, I filled in some more transmission fluid. I started the car and at the instant I moved the gear lever into "D" the engine stalled. I could not get the car running anymore.
Can it be that due to the fact that I used the wrong gasket that transmission fluid got into this servo area and blocked something in that?

Greetings

Ford Explorer 92 XLT with code 629

Hi,

I am not so familiar with this forum yet. I wanted to get a hold of you but I couldn't.
What would be the procedure to contact you directly?
Anyway, in the meanwhile I got the right gaskets to mount the valve body.
I did that yesterday. However, the problem persists. I cannot get the car started anymore. I can turn on the engine and I can switch to the different gears. But as soon as I release the brake the engine stalls.
I called a Ford expert today and he told me that due to the wrong gasket I killed something in the transmission and that I have to take out the transmission to fix that.
I would like to know your opinion on that. Do you really think that the transmission has to be taken out? And if what do I have to look for?

Wulf

I've moved your post into this thread since the band adjustment chart is another subject. I don't think that anything is ruined. Did you use the regular or thick gaskets? Did you check the pressure with a 0-300 PSI gauge in all gear settings?

Ford Explore 92 XLT with a code 629

Hi,

I ordered the gaskets and I used the .15 thick ones for the lower and the upper.
I did not do any pressure reading because I did not know about that. What do I have to do and what findings will be coming out of that?
Do you think that the problem can be resolved without taking the transmission out?

Wulf

 

[BrooklynBay]

# 10 in my list of useful threads explains how to check the pressure. Each gear ratio has its own pressure range. Low pressure will prevent it from shifting correctly.

Hi,

I glanced over this series of threads but I didn't study it yet. I will do that tomorrow.
My question is: In case the pressure reading is low what will be the consequence? Do you think that the damage can be repaired in the valve body itself?
