thats water under the bridge now.
sure wrong ATF is wrong, what is the point there/?
the correct fuild is clearly stated in the oper guide and fsm.
ill quote the FSM

MoparT ATF +4, Automatic Transmission Fluid is the recommended fluid for DaimlerChrysler automatic transmissions.
Dexron II fluid IS NOT recommended. Clutch chatter can result from the use of improper fluid.
MoparT ATF +4, Automatic Transmission Fluid when new is red in color. The ATF is dyed red so it can be identified
from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an
indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually
become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and
color cannot be used to indicate the fluid condition or the need for a fluid change.
DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic
transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid

when you buy AFT, it says on rear,
ATF +4
ok for chryrler and jeeps. in clear English, if not do not buy it.

mixing brands can be an issue, that is risky
best is full flush, with one brand, nothing is better,
here is one random example of those words.

Urgent - Stuck at a Campsite and Won't Hold Transmission Fluid???

Smoke may indicate a transmission leak, with fluid getting on the exhaust system. Puddling underneath when adding fluid seems to confirm that.
We can only hope that it didn't burn up any internal parts.

A few questions that might help you to get an answer:
1) Does the dipstick indicate full, or close to it?
2) Can your son be more specific as to where the fluid is leaking, and how much? Whether it is from the front or back part of the transmission, or elsewhere. Also, is it leaking out a LOT of fluid when he adds some?
3) Is the pickup parked on level ground? If not, which end is pointed up?
4) We are talking about a rear wheel drive P/U, not a 4x4, right?
5) Has he tried to put it in L1 if the pickup has it?
6) He knows to add the fluid while the pickup is running, right? Just making sure.

Sorry for all of the questions. Hopefully it will narrow down the possibilities.

I have a Volvo s40 2003 and I need to add a little power steering fluid. It looks like the o-ring on the cap is a little worn and the top of the cannister is "damp" when I check it, haven't seen...

1. Power steering fluid DOES need changing because it deteriorates with time and use.

2. You use exactly the fluid type and spec which is specified in the owner's manual . The type of PS fluid to be used depends on the type of PS system fitted to your particular car. These systems can be and are changed during a model run .

3. The fluid you have in the car is red because it is Automatic Transmission Fluid (ATF). Only use the type of ATF specified in the manual. For example if it states use ATF Dexron III or if it states Mobil ATF 3309 or another type only use that spec ATF. (I believe you will have Dexron III product in the car now and it will be the non-synthetic type).

4. You can refresh the PS fluid over time yourself by sucking out some fluid from the reservoir and adding fresh fluid. It is easy to pump out fluid using the pump fitting removed from a plastic trigger spray bottle. Just unscrew the spray nozzle from the tip of the trigger unit before you use it to pump out fluid. Remove and add fluid to the reservoir 5 or 6 times or more over a couple of weeks and you will eventually renew most of the PS fluid. Do not remove fluid once it drops to the level of the top of the top hose connected to the reservoir and then just top up each time to the correct level in the reservoir. It's really that easy.

I am seeing a small amount of transmission fluid under my 2003 jeep liberty. what could be causing this?

A loose drain plug in the transmission pan, a loose bolt in the pan, a bad gasket. It could be coming from the power steering as well. Check the resevoir and hoses.

Transmission fluid leaking

Bars leak is ok, but if it is a seal, you'll need to drop the tranny pan and replace it. I don't know about Mercedes, but usually you have to remove the exaust pipes to take the pan off.

Automatic transmission

Fluid can leak out of the driveshaft seals, the input shaft seal, the transmission pan gasket, the torque converter or the ATF cooler and line connections. If the fluid level gets low, the transmission may be slow to engage when it is shifted into drive. Gear shifts may be sloppy or delayed, or the transmission may slip between shifts. If the fluid level is really low, the transmission may cause the vehicle to not go at all.fluid level should be checked when the fluid is hot with the engine idling, the parking brake set and the transmission in Park. If fluid is needed, add only enough ATF to bring the level up to the full mark. Do not overfill because doing so can cause the fluid to become aerated, which may affect transmission operation. If the dipstick reads low, the transmission is probably leaking. So look underneath to see where the fluid is going. If there are no visible leaks, check the radiator for ATF in the coolant. The ATF cooler inside the radiator may be leaking and cross-contaminating the fluids.
You should also check the condition of the fluid. Some discoloration and darkening is normal as the fluid ages, but if the ATF is brown or has a burnt smell, it is badly oxidized and needs to be changed. Varnish on the dipstick is another indication of worn out fluid.
You can also do a "blotter test" to check for worn fluid. Place a few drops of ATF on a paper towel and wait 30 seconds. If the spot is widely dispersed and red or light brown in color, the fluid is in satisfactory condition. But if the spot does not spread out and is dark in color, the ATF is oxidized and should be changed.
Many transmission experts say most transmission problems can be prevented by changing the ATF and filter regularly for preventive maintenance. How often depends on how the vehicle is driven. For some vehicles, this might be every 30,000 miles or two years.
The harder the transmission works, the hotter the fluid runs. The life of the fluid drops quickly once its temperature gets up above about 200 degres F. Installing an aftermarket auxiliary ATF cooler that is parallel to the OEM ATF cooler is recommended to keep fluid temperatures down on vehicles that are used for towing or are driven hard.
ATF also becomes contaminated with normal wear particles from the clutch plates, bushings and gears. The filter will trap most of this debris before it can cause problems. But many older Asian transmissions only have a plastic or metal screen that does little to protect the transmission against internal contaminants and nothing to keep the fluid clean. On these vehicles, changing the fluid is the only way to get rid of these contaminants.
When adding or replacing ATF, use the type specified by the vehicle manufacturer. GM, Ford, Chrysler, Honda, Mercedes and others all have their own specs for ATF. There is no such thing as a "universal" ATF that works in all transmissions. Some fluids meet a variety of specifications, but cannot meet them all because of the different friction additives that are required.
Ford has three automatic transmission fluid specifications: Type F (a non-friction modified formula for most 1964-81 transmissions), Mercon (a friction modified ATF similar to Dexron II for 1988-97 transmissions), and Mercon V (Fords latest friction-modified formula, introduced in 1997).
