Transmission cooler

I know this might wrong spot but I hang out here and I figured someone here would know the answer.

I'm heading back home to MI for a baby dedication and while there want to help my son install a trans cooler. I will see him about 5-6 hours.

Vehicle..94 F150 4x4 with the E4OD. How long should it take to install this cooler. I'm a pretty good wrench and he is learning. Just I have never done a trans cooler.

Do I have to find a transmission temp gauge specific for transmissions? How do I find the HOT line compared to the return line?

Thanks for the help.

The hot line from the transmission comes out of the front of the transmission. It is routed to the radiator cooler. DO NOT REMOVE THE RADIATOR COOLER. The out from the radiator cooler goes to an air to oil cooler. From that cooler it goes to the rear of the trans. Are you planning on replacing the air to oil cooler? And why?

There are transmission specific temperature gauges. You need a gauge that has a sensor with a 1/8" NPT thread. Install the sensor in the test port on the driver's side of the transmission.

Hiw much time should we alot to complete the project? Yes we will keep the rad cooler but it did not come with an auxiliary cooler. He needs to an aftermarket unit because he is towing a camper and wants to be safe.

Not knowing your level of expertise, I'll take a SWAG and say a couple hours.

Temp gauge

Does the temp gauge HAVE to be mounted on the trans or can it be in the cooler line?

It can be put inline with the cooler line.Best to put it inline with the hot side line.

Thankyou for the answer. What I meant was does the temp gauge have to be mounted on the transmission itself OR can it be mounted in the transmission steel line? If mounted inline, does it take a different type of gauge to be mounted in line?

I found a coolent temp gauge that would read the correct temps but the probe was waaaaaaay to long.

You can mount it anywhere you like. It's your truck.

How high does that gauge read? If you put the sensor in the line to the cooler you'll need a gauge that reads up to 320°F or you'll just have the gauge pegged whenever the truck is working hard.

I recommend putting the sensor in the test port because that is a good indication of the actual temperature of the transmission. The line to the cooler is hot enough that you'll scare yourself quite often.

Thank you

To Mark and the others.

Thank you for the help and insight. I'm heading to my sons tomorrow (Monday) and it is suppose to rain all day. I think tomorrow is out because he does not have a garage or lento to work under. I still learned stuff so that is a good thing.

Thanks again to all fir tge help.

Cooler installed. All went well. Took him and me just over a hour. Most was him deciding to go vertical or horizontal.

Thanks again to everyone for the help.

Agreed with the temp sender location. I have one in-line with my hot line on the C6. It consistently reads 210F, and pegs to 250F if driving it really hard. The gauge doesn't go passed 250F.
