Overfilled transmission - 2002 Dodge Grand Caravan

No that will not cure problem. the problem occurred by overfilling . Overfilling will result in damage to transmission. here is more info,

How Does Overfilling Cause Problems? If you overfill the transmission, you will find that the fluid may foam, and that can lead to erratic gear shifting. Other problems can include transmission damage and oil starvation.

If it's a manual transmission then there should be a check plug on the side of the transmission. It should have a 4 sided plug you can remove with eather a 15 or 16 mm open-end wrench or an adjustable (crescent) wrench. Don't overfill, but keep it within 1 inch of the bottom of the check plug hole. Carefully use an allen wrench to check. If the vehicle has an automatic transmission and it has a transmission dipstick, then you can fill it through the dipstick tube but again do not overfill. Drive after filling and with the oil warm ensure the oil level is within the warm/hot cross hatches on the dipstick. Do not overfill. If there is no transmission dipstick on the automatic, then take it to your dealership to fill.

It could, because as the fluid get warm it expands. As it expands it might not flow thru the system as it was designed too. You might check your motor mounts also. I had a mini van that i thought the transmission was shot. It would **** and bounce. After getting under it I found 2 of its motor mounts were broke. When I fixed the mounts the jerking and bouncing went away.

If your vehicle has the CVT for the transmission, you must use the proper fluid first off. (Nissan NS-2)

There should be a drain plug on the transmission. These transmissions dont have a cooler lline that runs through the radiator to cool the fluid like older vehicle, some of them have a cooler built into the transaxle assembly that actually has coolant running through it. Below i have included a list of the various transmissions used in this vehicle, be sure to use the proper fluid or this will ruin the transmission very quickly and will void any warranty (if still available). You can also check the handle on the transmission dipstick, there should be a label stating which fluid to use.

*Note: Do Not Overfill the fluid, any slight overfill will cause poor operation of the transmission. If there is a way for you to measure how much you drain out, i would strongly recommend doing so, and be sure to put that same amount back in, as to reduce the chance of overfilling.


Hope this helps...

Your transmission is not equipped with a dipstick. (At least, there is a good reason you can't find it, Huh? You really aren't blind after all...LOL!)

To check your transmission fluid level, follow this procedure:

1. Ensure that the vehicle is level, with engine running at idle and parking brake applied. The fluid temperature should be cold. (after sitting for several hours) Move the selector level through all the gear positions and end in PARK.

2. Let the engine idle for three minutes and open the OVERFILL screw on the bottom of the transmission pan. The transmission is filled through the OVERFILL screw hole. The fluid will seek the correct level and will flow out of the OVERFILL screw hole. (See picture)

P.S. take a drain pan with you under the vehicle...you will need it.

On 1996 and later models, the transmission uses an overfill screw instead od a dipstick. On the transmission pan there are 2 screws, one is the drain plag and sits lowest and to the rear, the overfill screw is to the rear on the passenger side, this is where you fill with fluid until it just starts to run out of the opening.

Transmission cap? To add fluid? If that is what you mean, there is no cap and filler tube. You use an automatic transmission fluid funnel (long and thin) and refill the fluid through the transmission's dipstick tube. Pour the fluid in slowly and check level often to avoid overfilling. Use the correct ATF specified by GM and DO NOT overfill your transmission. I hope this helps.

CAUTION: DO NOT OVERFILL.
Overfilling will cause foaming, loss of fluid, abnormal shifting and possible damage to the transmission.
1. Park the vehicle on level ground and apply the parking brake firmly.
2. Check fluid level with engine running at idle.
NOTE: Be sure that transmission fluid temperature is below 30degrees C (86degreesF).
3. Move the selector lever through all gear ranges.
4. Move the selector lever to “Park”.
5. Let engine idle for 3 minutes and open the overfill screw (1).
6. Add released transmission fluid until it flows out over the overfill screw opening.
7. Let engine idle until a fluid temperature between 32
C (90
F) and 57
C (135
F) is reached, then close the overfill screw (1).
Torque: 38 Nm (3.9 kg·m/28 lb ft)
NOTE: To prevent fluid leaks, the overfill screw and oil drain screws gasket must be replaced each time these screws are removed.

CAUTION: Do not open overfill screw with engine stopped.
CAUTION: DO NOT CHECK FLUID LEVEL UNDER THESE CONDITIONS:

Immediately after driving at sustained highway speeds.

In heavy city traffic during hot weather.

If vehicle is towing a trailer.
If the vehicle has been operated under these conditions, shut the engine off and allow the vehicle to “cool” for thirty (30) minutes. After the cool down period, restart the vehicle and continue from step 2 above.
