Tranny Problem Help!!!!
When backing my trailer into its spot after towing it home, it lost all the tranny fluid , it came out right between where the motor and the tranny come together! And it just boom lost tons of fluid. What could have caused this. It is a 1993 F 250 with a 460 in it! 4x4. Thanks for all of your help

Could be the front pump seal.It is behind the torque converter.Seal is inexpensive and not that hard to replace , but if that's the problem it looks like the tranny has to come out to get at it.Or if the torque converter has a drain plug on it it may have come loose and started to leak.If there is an access plate you can check that with the tranny in the vehicle.Remove the inspection plate and put a breaker bar on the harmonic balancer snout nut to turn the engine by hand until the plug comes into view.With the plate off you may be able to get an idea where the leak is.It is a little tight down there.Information is based on my experience with a 88-f150 AOD tranny 2-wheel drive.

so
You think it might be something fairly easy to fix, about how much do you think to take it in to a tranny shop as I really dont have to the proper knowledge or space to do that kind of work!
And anyone from Oregon have a reccomended tranny shop!@

If it is the seal it is not hard to replace. The work is in the removal of the tranny.I am not familiar with 4 wheel drive but it must envolve more work. A lot of other little things have to be removed and on a older truck things can break do to rust and age. Until someone has a look at it at this point it is all speculation. All I can offer is have someone who you trust , that can do the diagnostics,and knows how to do these types of repairs should look at it. It could be something quite simple.You need to be carefull.

Well I talked to a local tranny shop today, and they told me that this was a common problem on these and that if I filled it up and started it back up, now that it has cooled down that it would not leak, they were right on this theory, now my question is , is it ok to drive this way or do I need to take it in and have this seal replaced just to be safe!

I don,t have any experience with this problem, but on page 3 of this section there is a post regarding 1987 ranger a4ld that overheats and spills fluid. This may be of interest to you.Some of the posts are talking about tranny coolers to solve this problem.Good to hear that you are back in business.

One last question, I have got mixed reviews from people, and tranny shops that I have talked to. Most shops have said that with the circumstances my seal failed simply because it got hot and tranny fluid expands when hot and forces itself out, and as long as I shut it down right away no damage would of been done! And that all I need to have done is a new front seal and the bushing and o ring to the pump and everything would be fine.
One of the shops that I have talked to says it had to be caused by something else in the tranny being week and needing some work! And that they would need to look at the tranny and go from there!
Question is do you guys think I would be fine just replacing the seal and pump bushing , or do I need to look further into this tranny!

My best guess is you are fine just replacing the seal and pump bushing though I have no hands on experience with your trans. Letting lord knows who mess with the guts of your unit can sometimes lead to even more problems. How many miles on it?

Often when the tranny overheats for a short time it will spit fluid out the front seal.
Backing up with a trailer is one of the best ways to overheat the tranny. No airflow thrru the cooler, slow speeds, a heavy load etc. I have had this problem with my 8000# trailer backing up a slight incline for about 600 feet after a long hot drive. The fluid temp spiked from 200 to over 230 if I recall and then it leaked.
Usually after cooling down the seal will be back like normal. So check for fluid color and smell to make sure it isn't burnt, top up and drive a round and see if it leaks. If not then you are OK for now.
I usually try to make backing up time as short as possible to prevent a repeat of spilling fluid.
Good Luck,
