What are some causes of the E4OD tranny blowing the front pump seal after rebuilding? Pump bushing, seal and torque converter were all replaced...
YOU COULD HAVE A BAD SEAT WERE THE SEAL GOES INTO MAKE SURE THERE IS NO GROOVES OR CRACKS THERE

SOURCE: 95 ford escort transmission leak
Dont waste your time and money trying to use a transmission stop leak product, they don't work on large leaks, you say the leak is excessive in this case the you must remove the transmission to access and remove the torque converter, after you have removed the torque converter carefully inspect the torque convert imput shaft for wear and also you will need to visually inspect the transmission front pump bushing for wear also, I have seen it all to often people just replace the seal thinking it was just a seal failure, well more times than not there is a reason for seal more than just the age of the seal, excessive wear on trans pump bushing and torque converter imput shaft is usaully the cause, check and repair those as good practice during this repair unless you just like to do the repair over again for free... also check the torque converter run out, sometime when they are repaired they are welded back together somewhat crooked which will cause it to spin off of a true center, this will cause immediate damage to transmission. Check also your engines crankshaft end play for looseness this can cause wobble which will transfer to transmission causing this problem as well... do the repair thouroughly and who ever does it for you have them check all that I listed and you should get a good repair which will last without issues.... please rate my help thanks...

it might have just run low on fluid while driving,the front seal may not have been installed correctly,or the cooler lines or cooler might be plugged causing the trans to overheat which will cause it to leak a steady stream...for example,my 94 bronco with a e40d acted like that too when i worked it really hard pulling stumps out in the summer last year,it leaked out really bad until it cooled down,i put 20,000 miles on it since and it doesnt leak not even a drop.so mine was just overheated really bad.As for if it is the same between vehicles it is only if both trucks are a big block,and if both are 2wd.

for it to blow the front crankcase seal you must be building up pressure in the sump.therefore you must have blowby,does it use much oil? i think you should talk to whoever rebuilt it ,i wont point the finger but this should not happen at 20 k

the E4Od does not have a bypass cooler line on the case. The 4R100 has the bypass cooler it is located on the passenger side if the trans. it goes from the rear cooler line follows the case to the front cooler line, and is attached with 7/8" banjo bolts. the bypass cooler was designed to keep the fluid in the transmission until it reached operating temp it "bypasses the cooler at the radiator until trans fluid needs to b cooled

Yes, I would definiately replace both, especially with what all that is involved in removing the transmission. I would also replace the transmission fluid in the torque converter and transmission. Refill the fluid in the torque converter before reinstalling, and make sure you have the torque converter fully seated into the transmission when reinstalling.
