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.

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.

I have transmission oil leaking between the engine and transmission what could be the cause?


front pump gasket or front pump seal either way tranny will have to come out to rectify and would need to figure out what caused leakage like cracked flywheel causing torque convertor wobble could be loose torque convertor bolts but you should be able to tell that it would cause a rapping noise

Car transmission leak


May need a new bushing in the pump that supports
the converter hub
The new or rebuilt converters don't have very good tolerance
on the hub,they run out
May have to take converter to a shop that does
their own rebuilds on converters, to have hub checked
for run out.They do much better work then say Daco
or other big names in the converter rebuild arena

Transmissions on a Ford F250 with a 460


You more than likely have the E4OD tranny in the truck. These transmissions are very prone to failure and problems. They are very expensive to rebuild and or replace if only using an exchange unit already rebuilt. I have rebuilt many E4OD trannys and would not recomend that particular tranny. Average exchange rate for a rebuilt is anywhere form $ 2800.00 to $3500.00. If you are considering buying this truck look for a manual tranny version instead.

E4OD starts in 2nd or 3rd when cold


The E4OD is a complicated tranny and unfortunately prone to many problems. There are three shift controlling solenoids inside the tranny mounted to the valve body. Without being able to actually drive to evaluate it makes it very hard to give you a starting point for trouble shooting. I have rebuilt many of the E4OD transmissions over the years and found them prone to many problems. That's why Ford quit using them. A tranny shop can hook up to two different line pressure ports to evaluate the problem. But, be warned they are going to recomend a rebuilt be installed. You will be looking at around $ 3300.00 dollars for the rebuilt unit.

Transmision


That is a lot of miles on the tranny. Being a Ford it probably has the E4OD tranny. The E4OD has several clutch packs in side. Sounds as though your direct drive clutch pack has gone out. Also the torque converter has a lock up mechanisim in side which may have given up the ghost . This tranny has improved over the years from the origional version. But, this tranny needs frequent service if towing a heavy trailer. Once the fluid gets burned it needs to be changed immediately or problems will result if you let it go and try to change later. Just to purchase a rebuilt if it is a E4OD will be around $3400.00. If you want to rebuild it the parts cost for just a basic kit will be around $900.00 to do it correctly. There are many hard parts to check for tolerances internally. By hard parts I am referring to sun and planetary gears and what not. I hope this has helped. I have rebuilt many Ford trannys over the years and the E4OD can be problematic at times. The newer versions are more reliable.
