Transmission pan bolts torque

See the attached pic. Let me know if this helps.

Hi,

I found that on Alldata. It's an excellent manual and I went under transmission torque specs. With that, it should be correct.

Please feel free to let me know if I can help. Also, I realize 9 ft/lbs seems loose, but you are placing a steel bolt into an aluminum housing. They strip easily, so be careful. Plus, you don't want the gasket to squeeze out from it's positioning.

Take care and let me know if you need anything.

Normally, when we change topics, we request a new post, but this is still related.

First, you are very welcome. I'm glad I was able to help. As far as a screen, there isn't anything like that used on this vehicle. Now, the idea that it is slipping at such a low mileage is really odd. Is the noise you hear loud enough to record and upload for me to hear? Also, has the check engine light come on at any point?

As far as the noise, if there are no codes, the first thing I would do is what you already have done. I would have done a few general inspections such as axles joints, made sure there was nothing with the torque converter or anything loose. If everything appeared good, I would then check transmission line pressure to confirm there isn't something happening to lower pressure, which can cause issues.

Tell me, are you certain the sound is from the transmission? The idea that it feels like a misfire makes me question other things. Just for the heck of it, take a rubber mallet and tap on the exhaust to see if the insides of the catalytic converter is loose and rattles. Something could be blocking exhaust flow, which will create interesting results, such as misfire, power loss and so on.

If you look at the pic below, it shows step 1 of checking for a soft shift or slipping. Note that it indicates it be scanned. There are a number of things that can cause it, but it becomes a guessing game if there are no diagnostic trouble codes. That is why I would check line pressure first.

When you say the transmission slips, do the RPM raise but there is no pull from the engine? Also, does it slip in all gears or is it one specific shift. For example, first to second slips.

Let me know.

Rapid clacking sound and slipping sounds like a failed intermediate clutch. Common failure in the 4F50N trans-axle. The clacking is from the clutch engaging enough that it takes up any slop in the gearing, then it hits the torque limit the bad clutch can handle and it slips and the gear train releases. They also have an issue with the torque converters failing and making a lot of noise. That usually sounds like a couple of steel pans banging together, the clue if that is the case would be that the noise stops with the transmission in OD and the converter clutch engaged so the internals are not moving relative to each other.
Not something that can be repaired in the vehicle though.
50,000 is an early failure unless it was run hard, but that trans-axle isn't know for reliability.
FYI if you replace or rebuild it, fluid and filter every 25,000 to 30,000 can help them live longer.

Yeah, sorry about that. Ford was investigated about the lack of reliability in the entire line up of these units starting in the mid 1980's and up. Ford changed internal parts all the time but even the new parts were failing as fast as the old ones, or they would fix one issue, another would appear. If you have a good transmission builder in your area you might talk to them and see what updates can be done. The guy I use curses at me when I show up with one, so be prepared!

That's a good price for a drop in. About what my guy gets for a re-build.

The transmission comes out the bottom. The hardest part is usually getting the car up high enough to get it out. You use an engine support to hold the engine up, then drop the cradle out from under it and then remove the trans-axle. Book time is about 8 hours to do the job.

For the same info the shops and we use you can get Alldata DIY or Mitchell for $30.00 a year. Both will show the removal and install as well as a lot of other information.

Tool wise the pictures are the special tools. Out of all of the listed pieces the only one that is really handy is the tie rode tool.
The engine support is a couple legs and a brace that set over the engine and bolt to it on the exhaust manifolds. I've used a regular engine lift, or make a simple crossbeam out of a 4X4 cut so it goes across the engine bay and on the strut towers and core support. Then a chain to a couple handy spots on the engine.

The slide hammer can be replaced with a couple short pry bars, it's used to pop the half-shafts free from the transmission.

Based on your description, it sounds like a pressure related issue. Here are directions for testing transmission line pressure. It also indicates possible causes based on results.

CAUTION: Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If the line pressure is low at stall, do not carry out the Stall Speed Test or further transaxle damage will occur. Do not maintain wide open throttle in any transaxle range for more than 5 seconds.

This test verifies that the line pressure is within specification.
1. Connect a pressure gauge to the line pressure tap.
2. Start the engine and check the line pressures. Refer to the line pressure chart to determine if the line pressure is within specification.

3. If the line pressure is not within specification, check EPC pressure.
4. Connect a pressure gauge to the EPC pressure tap.
5. Start the engine and check the EPC pressure. Refer to the line pressure chart for specifications.
6. If the EPC pressure is not within specification, GO to Pinpoint Test E to diagnose the EPC operation. If EPC operation is OK, refer to the line pressure diagnosis chart for line pressure concern causes. See: Automatic Transmission/Transaxle > Pinpoint Tests > Test E: Electronic Pressure Control (EPC) Solenoid

Let me know what you find. I hope it's a simple fix. I have to be honest, these transmission usually don't fail like this.

Take care,
Joe

You should be able to get a pressure test gauge at a parts store as a loaner tool instead of buying something as a one time purchase. Both the line pressure and the electronic pressure port are on top of the transmission. To the left of the electrical connector.
