I have a 1994 Ford F150 with Manual AOD Transmission Overdrive.
The transmission runs hot when towing or under strain.
Transmission fluid comes out of dipstick when hot and towing in 2WD, not in 4WD.
Does not do it when not towing. Does not do it when the engine or transmission is cold.
Any ideas what is causing this issue.

Thank you;
David

 

The first thing is to identify which transmission that your truck has, it seems as if you do not know. Second, make sure that it has the correct fluid in it. Third, if you are towing you should be running a large transmission cooler in front of the radiator, in case that you are not.

 

I don't believe the AOD was put into 94"s. The last year was 1993.

 

Come on guys so he's misidentifying the trucks automatic transmission but the question is straight forward, why does it heat up when towing. The first culprit would likely be the fan clutch followed by the radiator, antifreeze and the general condition of the cooling system. But the op should hear the fan clutch roaring when towing. So that's my answer fix the cooling system fix the problem.

 

If it's so straight forward, why are you so wrapped up with his cooling system when his engine is doing just fine? I know the tranny cooler is in the radiator. I would buy into your analysis if the engine was running hot too. He said his transmission is running hot and spewing fluid out the dipstick when towing, the engine is unaffected from his description.

I would make sure he is not dealing with an overfilled transmission. Maybe fluid is foaming up causing slippage and generating excess heat. If all that checks ok, might be time for an external cooler for that "AOD" but my money is on an over filled tranny.

 

Relevant information. Spewing hot fluid could be foaming fluid or overfilled.
An auxiliary transmission cooler is always recommended when towing.
You're right, the fan clutch / radiator / thermostat should be the first things checked for proper operation when there are cooling issues.

 

Well see there you go trying to give an actual solution not telling him he doesn't have an AOD or he needs to fill in his signature.

I don't think your solution would differ if the trans was AOD, 4R70W or E40D. Not a bad idea to clarify the transmission but then why not give input about the problem at the same time. At least you didn't break his post into small sections with a snappy reply to each one.

 

Trying to be helpful in my own way Sir. I was asking for clarification not because I didn't know that he didn't have an AOD, but because in the process he would learn what he does have. In my view this teaches something without being negative. Perhaps your way is better.

Sorry that you feel the need to be critical of others and that you have had a bad day. Hope that it gets better for you.

Cheers

 

Proper communication is paramount in solving a problem. There can be TSB's pertaining to certain models which can be helpful in solving an issue. If you do not like when someone asks for more information, ignore it. Hip shootin without needed information solves nothing and it appears you did not fully comprehend is question entirely.
