The total capacity of the transmission is twelve quarts. How much you need to add depends on how much is already in the unit. Your best guide is the indicator on the dipstick. Level should be between the "add" and "full" marks on the stick with the engine idling in park and transmission warmed up to operating temperature.

Here is a guide to help you see how to do the job:

Please let us know if you need anything else to get the problem fixed.

I recently replaced the vacuum modulator on the trans because it was sucking transmission fluid into the vacuum line. Transmission fluid is all-new Mercron III and is full. Two days after replacing the modulator the transmission suddenly would not shift into the higher gears unless I took my foot off the gas. Once in a higher gear, it would downshift as soon as I hit the gas again. The check engine light did not come on. I replaced the modulator again, but the problem remained.
What should I check next?
Is there an OBD code for this?
Could it be a problem with the solenoids?

Your modulator needs adjusted. Pull the vacuum line and you actually stick a small allen wrench in there and adjust it. In to make it hang on longer, and let it out to shift sooner. Just turn it one turn at a time though.

Are you referring to where the transmission and transfer case bolt together? If so, check something for me. Remove the fill/check bolt (not the drain) on the transfer case to see if ATF comes running out.

Let me know what you find.

Yes, where the transfer case bolts to the extension that is between the transfer-case and transmission. Is there suppose to be transmission fluid in that area? That is my question, because I need to know if its the seal on the transfer case or the transmission that needs to be replaced?

I already have removed the transfer-case and fluid is slowly dripping out of the extension. So it would it be a seal on the back end of the transmission then?

Four wheel drive automatic,

We bought this SUV in August. A couple of weeks after, we noticed that it was leaking transmission fluid. We kept an eye on the fluid, however, this past weekend while on our way to a wedding, the truck started leaked very badly, there was smoke, and the transmission started to slip.

We pulled over, and the fluid continued to drain.

We had the truck towed back to our home, and the next day the fluids was refilled. We checked for leaks, and there were no leaks visible at all.
We took the truck for a test drive around the block several times, and still no leaks.
The truck was driven to my work place and, again, there was no leakage.

Can you explain what is happening?

Thanks

Sounds as thought the transmission may be getting hot and blowing the fluid out of the vent tube. If there is an internal problem, it could get overheated on longer drives, then the fluid is pushed out of the vent tube.

Yes. It should be right at the end of the transmission's tail housing.

Let me know if you have other questions.

When I put my car in drive it just drifts backwards. Eventually I
can get it in drive but it takes a couple tries. Does it need transmission fluid? Or I am afraid to ask, a new transmission?

Check the fluid first. Beyond that, yes you may need a transmission.

There is transmission fluid in the intake manifold and it is smoking like crazy. What is it and can it be fixed?

Yes it can. Suspect a leaking vacuum modulator. It has a vacuum hose hooked to it, and the transmission fluid is getting sucked into it, then into the intake manifold. The vacuum changes according to load on the engine so it is used, along with road speed, to tell the transmission when to shift. When the unit is leaking, little vacuum can build up in that line, and low vacuum is what you get when you push hard on the accelerator to take off fast, pull a trailer, or go up a hill. Those conditions make the transmission wait longer to up-shift, and it is the vacuum modulator that is responsible for telling the transmission what the engine load is. Yours is incorrectly telling the transmission you are under hard acceleration. That is why it will not up-shift.

GM used a vacuum modulator on all of their vehicles for decades. Chrysler never used one. They used a simple mechanical linkage hooked to the throttle. Ford used half of each system, depending on year, model, and which transmission was used.

Rather than trying to describe what it looks like, buy a new one from any auto parts store, then look for that part near the rear of the transmission. A single bolt holds a forked metal bracket. Remove that, then the modulator pulls straight out.

I checked the fluid in my SUV's transmission and it is not red but sort of brown. I know this is not a good sign. My question is, if I drain the fluid and replace it will that keep me going for a while or will the transmission fail soon anyway? A transmission rebuild is out of my budget (no job). So if you think that it will fail soon (it shifts fine right now) I will just sell it to some one who can afford to have it serviced.

Just replace the fluid and filter. Most commonly if there is not a noticeable problem now there will not be in the near future either. Half of the vehicles we do fluid and filter changes on have dark fluid. It is when the fluid smells burned that you have to worry. If you really want to be thorough, have the system flushed but that is a lot more expensive. Those flush systems really came about because of the finicky nature of the newer computer-controlled transmissions that are made as cheaply as possible. They need every ounce of help they can get.

Where is it coming from?

It could be one of several places but we need more information.

Transmission fluid is getting into the oil. Sounds crazy and no one seems to believe me but the transmission fluid level drops and the oil level rises. Oil smells like transmission fluid and changes color. Where can the transmission fluid get into the oil?
