Correct trans. replace proceedure???
1994 F350 turbodiesel 7.3idi e4od trans.
How should flush the lines? What sensors do I need to replace? Should I replace the trans cooler, or have it cleaned? What other thinks am I overlooking. Failed transmission was VERY hot when failure occured. Please advise.

As a transmission tech for many years first I need to know what transmission you had. Was it an overdrive or a 3-speed. As to the lines most good auto parts stores sell an aerosol line flushing spray kit. To the cooler I would take the factory one out of the mix and install the biggest stacked-plate style cooler you can find. The factory coolers in the radiator tend to clog and reduce fluid flow. Two of my personal trucks are automatics and they have 70,000 gvw coolers mounted in front of the radiator and they handle all my transmission cooling quite nicely.

Okay I would definitely have a reputable shop go through it. At the bare minimum you should have them do a shift kit along with all new electronics. An option would also be to get a heavy-duty converter instead of a stock replacement. I would personally go with a converter that has a multi-disc lock-up clutch and a billet cover to prevent slippage and converter ballooning. The closest place I can suggest would be Gilleece transmission in Large, Pa. They build all the converter I use and they know what they are doing. I will warn you in advance that you are going to spend a chunk of change if you decide to build this strong. If I remember right most shops are getting 2000 or better to build them now and that is for just a basic rebuild. To build this so it will live behind a strong diesel you will probably be in the very 2000 dollar range and possibly into the low 3000s. The last I heard a multi-disc converter was over 700 dollars for a cheap one and they may have went up. Hope this helps.

cooler and convertor key to e40d life
Get the best low pressure drop cooler you can buy the coolong sytem in theis trans supplies all hte lube oil to your planets bypass your radiator due to the problems that the other tech described.
Get the best convertor you can this is the other weak point and make sure that you have the updated pcm or you may get tcc codes there is a ford tsb that gives you the pcm part numbers.
AS far as the internals of the trans make sure it si at least up to 95 specs with updated center support and od sprag replace the electronics(solenoid body and range sensor), the Pump is a also a good upgrade at least check the boost valve for wear. and you can't go wrong with a shift kit but that would be the last thing I would spend money on
Good Luck

Also make sure when they do the rebuild they replace all the checkballs in the unit. I always suggest the shift kit as it is inexpensive and it comes with checkballs made of a synthetic rubber that is far superior to the original.

Brimmstone is right about the stock TC, they can not only fail in less than 80K, but when they do, they will often take the rest of the tranny with it by sending shrapnel through everything.
If you want to build up your engine at all in the future, you may want to consider a steel geartrain upgrade.

The best way to clean the radiator cooler and lines if with a hot flush tank(Ford
dealer should have one,was required for warranty labor claims about 3yrs. ago).
the oil to air(ota) cooler should be replaced,due to the internal ribs in the tubes hold
debri and release it later.Also install a cooler line filter in the return line,this comes with all the ford reman units as insurrance that you did not just waist 2k on overhaul.
