You should have the computer scanned at a transmission shop or a dealership. If you get a code P1811, that is the 'max adapt long shift' code. That means that the Electronic Pressure Control solenoid may be going bad. Normal wear and tear on the clutch material can also cause this code. Basically, it means that the transaxle is taking longer than 0.65 seconds to shift, and the computer commands maximum line pressure to avoid burning out the clutches. I have had good success with installing a shift kit on several of these transaxles (4T65e) to remedy this problem with no further issues. Visit and look for distributors in your area. The shift kit you need is the SK 4T65e shift kit. The kit comes with very good instructions. It is not a difficult job. If you can drop the pan and change your own fluid, you can install this kit.

David dont even waste your money on the transmission no slip fluid, its money you can put towards the new transmission. Once its slipping the stuff in the bottle is a waste of time. Learned this from past experiences, hope this helps. The reason the fluid is burnt is due to either worn friction disc or a fluid leak by the seals in the clutch pack causing the fluid to heat up and turn brown. Hope this helps.

How to Diagnose Automatic Transmission Problems

My transmission has a clunk sound coming from it rite as you start to accelerate and i found metal shavings in the pan any ideas of wht this could be

metal shavings indicate mechanical failure of the internals
you don't mention the make and model of the transmission but from experience some transmission have a badly designed band servo housing the is prone to breaking at the adjustment area
this gives a clunk as the bands are engaged , band slippage and drops metal into the pan
The fix is generally in car and relatively cheap
pull the pan and check for cracks in the internal castings around the band adjustment screw area
If it is more, have it diagnosed by an accredited specialist transmission shop and get a detailed quote for repairs before you accept the " tranny is s***** answer , need a new one" answer

2003 F-250 Super Duty. Why is it noisy in drive?

I would examine the color of your transmission fluid first. Is it bright red or is it turning dark? Does it smell burnt? These are signs of wear.

Next step is to drop the pan and examine for metal shavings and excessive organic band material. If these are present, you are pretty much in need of a transmission rebuild.

2000 Mazda MPV automatic transmission won't shift into 3rd.

The trouble with automatic transmissions, in cases like these, is that you may not have a choice but to have the transmission removed and disassembled to find the problem. If all that happened was a loss of fluid, it is unlikely something as simple as an external sensor or a linkage problem is going to cause your issues. At the very least, the pans would need to be removed and inspected for large amounts of debris. Even without loud noises, it doesn't take long for internal aluminum parts to wear or break when not properly lubricated.
With the pans removed, you can also inspect (and/ or change) the fluid filter. If there are no large pieces of metal found in either or the pans, there is a small chance you may be able to bring the van back to life. I have had moderate success using Lucas Oil Products in the past and use them quite a bit in my shop.
Keep in mind, this is a gamble and could cost as must as $250 for parts and labor (if you're not doing it yourself).
With the pans removed and no large debris found, remove the filter and let all of the fluid drain for at least 15 minutes. Then use spray parts cleaner to completely removed all dirt and old fluid from all the parts you can see.
Then install a new filter and pans with new gaskets. DO NOT use silicone sealer if the pans call for a gasket. This only breaks down with fluid and plugs filters.
At any parts store, find 2 quart bottles of Lucas Transmission Stop Slip. It's a little costly, but I've seen it bring worn transmissions back from the dead. It is also important to use high-quality, name-brand fluid. Most parts stores carry a store-brand, which is made by the same company that makes Valvoline. I use them every day and have never had a problem.
Add 3 quarts of transmission fluid to begin filling. Start the engine and idle for about a minute. This will begin priming the transmission pump and filling the torque converter. Stop the engine and add the 2 quarts of Lucas additive. The additive is very thick and will drain very slowly in cold temperatures. Keep the bottles inside and warm until you are ready for them. Once they are both completely drained into the transmission, start and idle the van for about 10 minutes to get warm. While idling, apply the brake and shift to reverse, then neutral and then to drive several times. If the transmission does not engage right away, check the fluid and continue to top off with fluid until it is at the full COLD range.
Once the transmission is full and the engine is warm, test drive the vehicle. If this procedure is going to help anything, it should start to take effect within 100 miles. If it doesn't happen right away, don't panic. Just drive the van normally without any sudden acceleration or stopping (hard acceleration can cavitate the pump due to the thick additive) until you start to see a change.
I know this seems like a lot of work just to "try" and keep your van going, but I've done this on multiple vehicles in the past. Again, it is a gamble...but it may just pay off. My shop typically charges around $200 for this service, but a replacement transmission could run in the range of $4000.
Good luck!!

Transmission slipping in first gear

If you take your Foot off the GAS PEDAL, will it go into the next gear? Transmissions shift by using PRESSURE and Opening the Solenoids Passages.

You may have a Solenoid Problem or a Electrical Issue, Normally if it is shifting out of 1st and going nowhere, I would suspect a Solenoid issue.

You may has also broke the Sun Shell inside the Transmission. This is not a Troubleshooting that I can go very far with you unless I hooked up my scanner but what you need is someone to put a Scan Tool on your Expedition and see what is actually happening. Sorry to give you the Bad news but I think at the minimum, you are looking at dropping your Pan and changing out a Solenoid but you could also have a major rebuild also...

Dodge 45 RFE transmission shifting hard only from 2-3 with no DTC's

Almost everything in a automatic transmission used to operated by the fluid flow. Nowadays transmissions have electrical parts too. I'm inclined to agree with your solenoid valve diagnosis. Did you notice any metallic debris in the bottom of the pan when you changed fluid?
If there is debris (and there almost always is) some may be in the bottom of the pan and some may be in the valve assembly. Hard acceleration means more fluid pressure and more fluid flow. Which may help the valve to operate. Some valves only operate a pilot circuit and ball check valve that further controls the major fluid flow.
Do you see any fluid around the modulator? And is the modulator port & orifice clear. Next time you have the pan off, see if you can pull the modulator and look at the mounting port and the orifice inside the modulator itself. If there is a dark colored square or rectangle in the pan. Wipe it off with a finger and check for grit or metal.

it may be a bad transmission modulator valve located on the side of your transmission,vacum operated. a sudden downshift or forward shift when unexpected is sign of a bad modulator valve or a vacum leak to the to shop around for a garage w/references when it comes to transmission work though. check all the vacum lines to your transmision,you need to look on the underneath side of your truck on the side of transmission for a loose or disconnected vacum line on the side of the transmission. when you feel the vacum line,follow it to the top of engine,the vacum line is about 3/8th line,and may be disconnected or losing air. to make this short,when you drive the car,start out in low gear and shift the transmission,manually from 1st to 2nd to 3rd does it do right with no slipping? if it does this right and shifts great manually,the modulator valve on the side of the transmissions bad,or a bad vacum leak in-between.thank you for choosing

Metalic transmission granuals in transmission pan

I have the same vehicle. Is this your first Transmission oil change? If it is don't worry about the shavings. Its break in stuff that should have been flushed out at 30k,60k and 90k. But who's counting lol. If flushed regularily them what he is saying is somewhat true. Its gears that are wearing not bearings. A rebuilt tranny goes any where from 1,900 to 2,700.
