changing front tranny seal

[strker]

I have a little experience with auto transmissions...i have pulled many for others to repair. now i need to put a front seal in mine it drips after pullin a load then it is okay without the load.does anyone disagree with going ahead and changing the front seal and if i change the seal is there more than one i should change also? i ve read many post where people have done the work just never much detail as to what they changed..the thing leaks only after pulled a 16' trailer 10 miles or so stop and go traffic..otherwise(without load) it does not leak..truck is a f 250 auto tranny no o/d light blinking and does have bigger cooler...

The torque converter seal is the only one you need to change. The hardest part is getting it kn ocked in without bending it. The best thing to have is a round pipe the same size as the outside of the seal and long enough to clear the input shaft.

The leaking seal is usually the symptom not the cause.
The seal usually leaks when the converter gets too hot and stops when it cools down.
The fix is to prevent it from getting too hot, additional cooler ect...
If it continues to get too hot it will continue too leak no matter how many seals you replace.
