Your transmission is either overfilled or cooler sounds like it is plugged and not letting your fluid cool properly causing it to foam and run out the vent. I would recommend first checking your fluid with the engine running and in park to insure proper levels then if that looks good pulling the transmission lines from the radiator and blowing air through it to clear any trash that may of accumulated. You can even purchase an external cooler to help cool your fluid just be sure that when you install it to make sure you install it after the radiator or the side that your fluid returns back to the tranny and not before the radiator.

How to check tranny fluid


To check and add transmission fluid on your Ranger:
1. Drive the vehicle 20 miles (30 km) to reach normal operating temperatures.
2. If driven in hot weather or city traffic, allow transmission to cool for 30 minutes.
3. Engage parking brake, start engine.
4. Press the brake pedal and move the gearshift lever slowly through all gear ranges.
5. Shift to P (Park) and leave the engine running.
6. Remove the dipstick, wipe clean with a dry lint free rag.
7. Install and fully seat the dipstick into the filler tube.
8. Remove dipstick and inspect fluid level. It should be in the cross-hatched area.
9. If necessary, add fluid in 1/2 pint (250 ml) increments through the filler tube until the level is correct at normal operating temperatures.

How do i check my transmission fluid


Fluid Level Check

Automatic transmission dipstick marks; the proper level for a hot transmission is within the shaded area

Check the automatic transmission fluid level at least every 7500 miles (12,000 km). The dipstick can be found in the rear of the engine compartment. The fluid level should be checked only when the transmission is hot (normal operating temperature). The transmission is considered hot after about 15-20 miles (24-32 km) of highway driving.
Although the transmission should be checked while the fluid is at normal operating temperature, do not check it if it is at the extreme high end of the operating temperature range. Wait at least 30 minutes if you have just be driving the vehicle in ambient temperatures in excess of 90°F (32°C), at highway speeds for a long time, in heavy traffic (especially in hot weather) or have been pulling a trailer.
  1. Park the truck on a level surface with the engine idling, then shift the transmission into Park and firmly set the parking brake.
  2. With your foot on the brake pedal, move the selector through each gear range (pausing for about 3 seconds in each gear), then place it in Park. Allow the engine to run at idle about 3 more minutes.
When moving the selector through each range, DO NOT race the engine.
  1. With the engine running at a low idle, remove the dipstick, wipe it clean and then reinsert it firmly. Be sure that it has been pushed all the way in, then pause 3 seconds. Remove the dipstick again and check the fluid level while holding it horizontally. The fluid level should be between the upper notch and the FULL HOT line. If the fluid must be checked when it is cool, the level should be between the lower 2 notches.
Most of the transmissions for the 4.3L engine are equipped with a flip-top handle on the dipstick. To withdraw these, flip the handle upward, then pull the dipstick from the guide.
  1. If the fluid level is low add DEXRON®III automatic transmission fluid. The fluid must be added through the transmission dipstick tube, which is easily accomplished using a funnel. Add fluid gradually, checking the level often as you are filling the transmission. Be extremely careful not to overfill the transmission, as this will cause slippage, seal damage and overheating. Approximately one pint of ATF will raise the fluid level from one notch/line to the other.
WARNING Always use DEXRON®III ATF. The use of ATF Type F or any other fluid will cause severe damage to the transmission.

The fluid on the dipstick should always be a bright red color. If it is discolored (brown or black), or smells burnt, serious transmission troubles, probably due to overheating, should be suspected. The transmission should be inspected by a qualified technician to locate the cause of the burnt fluid.

I have 60K miles. When is recommended transmission fluid change?


It should be done between 30,000 to 60,000 miles. 30,000 miles if you do lots of stop and go traffic like in rush hour and up to 60,000 miles if your out on the highway most of the time. (less gear change) As long as you service your transmission on a regular schedule, it should last you the life of the car. $100.00 service every 3 years is a good investment since a transmission replacement is around $2,300. Hope this helps and good luck.

Need to add tranny fluid to '99 Rodeo, but where??


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 32C (90F) and 57C (135F) 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.

I recommend a trans fluid and filter change first. It definately sounds like the problem is in the trans. If it was any sort of engine component you would have had a check engine light on.
