Here's How:
Before You Start: Follow these instructions carefully. Read and be sure you understand them before you begin. Gather together all of your tools and supplies before you begin. Never work on a vehicle that is only supported by a jack. Use jack stands to support the vehicle while you work. Work on a solid, level surface. Never jack a car up on dirt or grass. Remove the transmission dip stick and lay it aside for now. Jack up the vehicle and support it with jack stands. Some transmissions have a drain plug either in the transmission pan or on the case. Check to if yours has a drain plug and place your drain pan underneath it. If it does not have a drain plug, place the transmission drain pan under the transmission pan and remove every other transmission pan bolt. Leaving two pan bolts on each side, remove the rest of the pan bolts. Transmission fluid will start running out at this point. Remove the two bolts on one side carefully, allowing the transmission fluid to run out. Then loosen the other two slowly. When they are three or four threads from coming out, push the pan up, hold it with your hand and remove the last two pan bolts. Once the bolts are out, lower the pan and drain it into your drain pan. Look inside the pan. A grayish dust and some very small pieces are normal. If there are any big pieces or chunks, you have a problem. If this is the first time you have the pan down and it is a Ford product, you will see a small plastic plug. This is normal and not needed any more. Just throw it away. It is used in the building of the transmission only. Use the scrapper to remove the old gasket from the pan and the mating surface of the transmission. Don't put in any gouges or deep scratches. A wire wheel in a drill also does a very good job of removing the gasket. Most transmission pans have a magnet that collects the steel dust. Clean it off well and make sure you put it back in. I stick it on the mating surface of the transmission to be sure I don't forget to replace it. Clean the inside of the transmission pan as well.
When the pan is clean and dry, get the new pan gasket out. You did match it up before you dropped the pan to make sure it is the right one, didn't you? Take the weatherstrip cement and run a bead around the mating surface of the pan going completely around the bolt holes. Carefully lay the gasket on the pan and press it into the cement. Lift one corner at a time and let some of the solvent evaporate and stick it back on. When it is on good, turn it over and place it on a flat surface to set.
Now for the filter itself. This is where you have to be careful. Before anything, hold up the new filter and make sure it is the same as the old one. Depending on brand they may be some slight differences, but the mounting holes have to be exactly the same. Using the new filter as a guide, remove the mounting bolt(s) from the old filter. The bolts may have different lengths so make a note of the hole it came out of so you can be sure to put it back in the same hole.
When it is loose some more fluid will drain out so watch for it. Remove the filter and put it in a plastic bag so it can be disposed of properly. Climb out from under the car and let the fluid drain for an hour or so if you want. I let it go as long as I can just to get whatever I can out. Now some cars have a drain plug on the torque converter that will allow you to drain the transmission fluid from it. If your converter has one, remove it and drain the converter as well. Now, install the new filter and reinstall the drain plug into the converter, if you took one out. Take the pan and apply a layer of wheel bearing grease on the top of the pan gasket. The grease will seal the gasket and yet allow it to come off easily at the next filter change. Tighten every other pan bolt until they are properly torqued, usually 15 to 20 inch pounds. If they are over tightened the gasket will squash out and leak. When It's tight, clean the area and lower the car. Put in two quarts of transmission fluid, in Chrysler products I highly recommend using Chrysler ATF. Start the engine and let it reach normal operating temperature. Check the fluid level and add ATF until it is just below the FULL mark. With your foot on the brake shift it from reverse to drive 3 or 4 times. Recheck the fluid level and top off as needed. Drive the car for 3 or 4 miles and recheck the ATF level again and adjust as necessary. Check for leaks and you are done. If you need further assistance please let me know.

When im driving there is a loud droning noise,when it is in park the engine is fine,i just changed the transmission oil and filter,some times when you put it in drive you pull away and when it changes

Make sure the fluid level is full. The fluid level drops after shifting through all of the gears. Are you sure that you put in the proper transmission fluid?

2000 Pontiac Montana . Goes into gear hard when it shifts. Has 140000 miles on it.

It sounds like the pressure control solenoid inside the transmission. With that many miles I would suggest going ahead and rebuilding it. You need to remove the transmission from the van anyway to replace the solenoid. I have rebuild several of these, be sure to put in a shift kit, it makes a big difference. I've rebuilt them before and wasn't happy with the way it shifted, so I pull it back out, put in the kit and that did the trick. So, needless to say, I always put the kit in the first time. Although, I do know a guy that changed his filter and added some Lucus oil treatment for the transmission to the new oil, and he says he hasn't had that problem sence........makes me wonder.

You may be able to delete those codes. What repair required you to disconnect the cable? What changed? Is the transmission functioning. The solenoid is inside the pan on the valve body and controls Torque converter lockup. Did you disturb the wires while changing the trans. filter?

Jearking between shifts filter and fluid has never been changed 80000 miles

It sounds like you just need to service your transmission and request a transmission additive such as Trans X to be added to the transmission since there are high miles and low maintenance. This may help to prolong the life of your transmission.

The transmission takes a few seconds to engage. You can put it in any gear but you have to wait for it to kick in. After it is going down the road, it shifts fine, as long as you don't accelerate hard.

It's time for a trasmission fluid and filter change.

They are relatively inexpensive at most one stop auto shops, however your vehicle is extremely easy to change the transmission fluid and filter.

It is located under the front bumper on the bottom side of the engine. 10 to 16 bolts and the transmission pan is off, two to four bolts to remove the filter, and then reverse.

Please do not do this yourself if you are not positive you can do it correctly.

The good news is, if you get your transmission fluid and filter changed in the next 50 miles you drive, you are likely to avoid catastrophic transmission problems.

Yes it is hard to change. It is in the side cover of the transmission. The transmission will need to be removed to replace it.

Pontiac Montana has computer codes

Most GM it takes about 100 start cycle to clear any DTC codes that do not reoccur. As for the lack of power when accelerating could be a dirty fuel filter and needs to be changed.
As for the EGR Valve code it may be getting carboned up and need to be replaced or cleaned soon with carb cleaner. First try changing the fuel filter for your lack of power.
If you are ever going to have you Montana Rescanned and don't mind spending a few extra dollars, Have a Dirve Cycle DTC test done.
Good luck and hope this helps. Note: The program on the transmission on the Montana thanks to GM and there wisdom was made to slip when the transmission is cold to warm up the drivetrain quicker, which premature failure is common around 150,000 KM or 100,000 Miles just after the warranty. Regular transmission fluid and filter change will help exten the life of the transmission on the Montana.

Tune up

Slipping tranny can be caused by that. Rule of fixing cars is if not sure start cheap. Replace the Filter and fluid. Also it wont hurt to put in Lucas Transmission Additive with the fluid change. Change plug 2 ways if it has motor mounts on top then disconnect them and pull the engine foward. or

No need to rotate engine as I was told that sometimes this causes damage to exhaust link which is flex. First two plugs can be reached by going along the same channel as exhaust pipe from header runs. Last plug remove right side tire and you can reach up by body to change it. This one is blind, but it's possible.
