Transmission Fluid Change Questions.

I have a 2006 Commander with 4.7 V8 and 545RFE transmission. I want to ask some specific questions on how to change the fluid properly. I had some issues this weekend trying to do this.

1. How do you access the bolts alongside the exhaust pipe? The pipe blocks access to those bolts. I don't think a straight extension can work here. And how would you torque the bolts if this is in the way? I broke a Craftsman socket trying to remove a front bolt. The torque is supposed to be 105 inch pounds. That was enough for me to reverse course on this until I could get some ideas on how to R&R these bolts properly.

Once you get the pan down, how do you remove the old seal for the filter? I don't want to hack up anything in there. Is there a tool that can be used to make this go smoothly?

Are there anyother things to be aware of when doing this?

Thanks in advance...

Frank.

I changed my fluid and filters a couple weeks ago. To loosen the bolts I used a 1/4" drive socket with a Ujoint adapter and extension, the smaller drive seemed better suited to get around the pan/exhaust.
- I removed the old seal by taking a screwdriver and lightly wedging it under the seals' metal face until i was able to buckle it or slightly deform it enough to pull it out, being careful not to gouge the transmission. I had a seal puller but on the seal internally there is no place to hook on. For installing the new seal I tapped it in using a socket about the same size as the seal... Be gentle
-The pan filter has a Torx screw holding it in place, The cooler filter has plastic threads do be careful not to over tighten it, the filter should have directions on how far past tight to turn it.
- In all I refilled mine with almost 9 quarts of Mopar ATF+4 It was an easy job just messy, have lots of rags towels and gloves I did discover that if you buy the fluid in the 1 gallon jugs from Mopar its way cheaper than individual quarts. Don't forget brake cleaner, it makes that black gasket maker come off so much easier.

Had my transmission fluid/filter changed at my local garage that I do business with. He had trouble getting the pan to seal properly. Everytime he though it was good to go, it leaked--puddle on the ground. He even went to the local Jeep dealer to buy the proper seal. He did it one more time and then added a sealant inside and out for good measure. He let it sit overnight and called me that it was good to go. I picked it up and the following morning--puddle. Nothing I could do--I was headed to Virginia for a week. While in Virginia, every morning a puddle on the ground. I still get a small puddle (drips), but I suppose it's because most of the fluid has now leaked out. The Jeep ran fine all the way back to NY, and it's still running and shifting fine. Any thoughts? I've searched the forum--people keep referring to an O-ring somewhere. I checked the TSBs but saw nothing regarding an O-ring. I'm trying to arm myself with suggestions for my mechanic. Or should I just take it to the dealership? It's an 06 3.7.

I didn't use any special tools, just different types of sockets, and extensions. No u joints or anything like that, although that might make it easier.

I used an offset screwdriver to take out the seal.

Thanks for the details on changing the fluid. This is what I needed to know, and these are the types of things that can cause a project to fail if you are not aware. I didn't know the filter bolt was a torx head, and I'll make sure I have a complete set before I start. Also, I will take caution on that internal filter when I install it. It's good to know that you don't need a special tool to remove that filter seal. It seems like it's going to be the toughest part of the job; making sure not to harm anything when you remove it.

One more question, and it seems simple but....I checked my fluid yesterday, and there are two lower holes on the dipstick, and two upper holes for the hot measure. The two lower holes are 'filled' with fluid, and the two upper are not. (Trans was hot). I expected to see a solid line of fluid accross the dipstick like you would see when you check oil. But this was not the case. There was a light coating along one side of the dipstick. Seems odd that there is not a solid line. So what is the proper way to gauge if you have the correct amount of fluid in the trans? Do you go by the filled or not filled holes?

Frank.

From the Owner's Manual:

Fluid Level Check

NOTE: If equipped with a dipstick, use the following
procedure. If your vehicle has a capped dipstick tube, it
is sealed and should not be tampered with. Your authorized
dealer has the proper tools to ensure that the fluid
level is set properly.

Check the fluid level while the transmission is at normal
operating temperature. This occurs after at least 15 miles
(25 km) of driving. At normal operating temperature the
fluid cannot be held comfortably between the fingertips.

To check the automatic transmission fluid level properly,
the following procedure must be used:

1. Operate the engine at idle speed and normal operating
temperature.

2. The vehicle must be on level ground.

3. Fully apply the parking brake and press the brake
pedal.

4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).

5. Remove the dipstick, wipe it clean and reinsert it until
seated.

6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the “HOT”
(upper) reference holes on the dipstick at normal operating
temperature. The fluid level is only valid if there is a
solid coating of oil is seen on both sides of the dipstick. If
the fluid is low, add as required into the dipstick tube. Do
not overfill. After adding any quantity of oil through the
oil fill tube, wait a minimum of two (2) minutes for the oil
to fully drain into the transmission before rechecking the
fluid level.

NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at approximately 70F (21C) (room temperature).
If the fluid level is correctly established at
room temperature, it should be between the “HOT”
(upper) reference holes when the transmission reaches
180F (82C). Remember it is best to check the level at the
normal operating temperature.

CAUTION!
Be aware that if the fluid temperature is below 50F
(10C) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.

7. Check for leaks. Release parking brake.

To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.

Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks.

I read the manual this morning. But the thing is, I am not getting a defined coating on each side of the dipstick. Just a long smear on one side for several feet. The cold holes are filled and not the hot holes.

I'll recheck tonight just in case I did something wrong. If I still get the same thing, then I guess I need to go by the holes and ignore the sides of the stick.

Once again the manual does not help. It also says to use ATF+4 in my NV-245 transfer case. I can't believe my manual anymore.

If you have smears it's probably low. Just as you imagine you want a clearly defined section where the fluid is.
