That the fuel pump. Common problem that they start to leak from the weep hole before they go. Here's a link to replacement instructions. Did mine about a 4 hour job if your goofing off, maybe 2 hours if you just dedicated to wrenchin'

cool. Thanks alot man. This is a main reason my transmission went out. Ford and another place told me the fuel running down the back of my block and on top my tranny would heat up. Making the trans 2x hotter then it should be. Keep running like that and it just gave out. It will prob take me 5 hours. Im not that dedicated to that wrench. Thanks alot.
ps. Love the truck. wish i had extra money for it.
Thanks again.

Dont know who told you that fuel on top of it was the problem, they arent too bright. The main problem with these trucks is the TOTALLY WORTHLESS tranny cooler. First thing to do is fix the leak, cost is about 70 bucks from advanced auot parts. If the instructions tell you to take the turbo out, STOP THERE AND CONSULT THIS FORUM. the turbo does NOT have to be removed unless you have a cali truck, which you do NOT. Even if you arent that handy, 2 hours MAX for your first time. Then drive your truck to a local hotrod shop, and get the 26k tranny cooler. Cost here at my shop is about 45 bucks. Takes your tranny rom running 180 plus empty and 200 plus loaded to running 150 empty, and 170 loaded. WORTH ITS WEIGHT IN GOLD. WILL SAVE YOU A TRANNY REBUILD IN THE FUTURE. I promise.

i already have the 26k tranny cooler. Also just had the transmission rebuilt. I would run around 150 for a while then out of no where i would look down and it starts creeping its way past 180 and so far all the way up to 220 before i pull over. Whipped the diesel off the sides of the tranny. Wait awhile and fire it back up and it would cool back down to about 150 and then creep back up. It is the fuel on it. I have had 3 different people look, drive and check it out and they all agree. Im on my lunch break of fixing it right now though so thanks again for all the help. I guess we will find out if its really the fuel or not after i fix it. I would of never guessed it would be that till ford said it.
Thanks again

O.K.. I dont think thats what it is and here is why. Does your tranny heat up faster in the rain??? Of coarse not, the water has a cooling efect. I dont think that your fuel heater is working so well that its heating your fuel to 200 plus degrees and dropping it onto your motor while it runs of the back correct? So what this really means is that the diesel fuel is either
A) Getting so hot from the fuel heater AND NOT BURNING OFF that it is falling onto the tranny and heating it, literally like a boiling pot of water
B) Picking up the engine heat and tracking its way down to your temp probe for your tranny,
C) They put a junk tc in, with this stupid stall your talking about in an above post, and since your motor is designed to operate below that stall your generating WAY MORE heat than normal.
I opt for a modified C choice that whoever put that tc in and rebuilt your tranny has no clue what they are doing creating a driveable BUILT diesel truck. Just my .02

The fuel wouldnt have to be over 200*, just over the temp of the tranny case, which might be 120-130... then it would add to the heating, i think...

Fuel on the case won't cause the trans to over heat. Trans slipping could cause that heat. Something wrong with the rebuild could cause the heat. also perhaps the fuel is doing something to the sender for your temp gauge.

Correct you are TJ, but there isnt a way for the fuel to penetrate the top of the bell housing. there are no weep holes, and the motor would burn the fuel away before it seped thru the mating surface. So as I said, and you posted above, its either the fuel messing with the sender, which would also be on the wrong side but still possible as the sender usualy gets mounted on the drivers side, and the fuel runoff hole in the valley is the passenger side, OR (and I REALLY believe this is the one since the guy put a stall converter in a diesel over its peak operating range) the guy that did the tranny doesnt know a 700R4 from an e40d. Unless this was a BUILT pulling truck, it should have never had a stall converter in it, CORRECT?
