Its the transmission control model. it is malfunctioning and it will need to be replaced.

This module initiates the shifting signal that is then carried out by the shift solenoids in the transmission case. replacing the module will fix the issue.

    If possible, i will need your complete engine specs so that i may gather the information you will need.

    Whats the liter in the engine?

    Ok, this device will cost $303.99. if you are not familiar with your transmission set up, this can be quite hard but, if you know a bit about the layout, its not that hard.

This sounds like clutch packs in the transmission. Unforutunately that means a remove and rebuild. The plat you are talking about is a dust cover. You need seals too.

Do you mean upshifting starts way early? Going from 2nd to 3rd in other words?
Ireally don't know your transmission,but the alternator problem might've possibly spiked and hurt your shifting solenoids in the ******. don-ohio (:^)

Got a 1995 F350 dually and the overdrive light flash sometime. When it does it make the transmission shift hard. If you stop and cut truck off the light go off. So what is the problem?

sounds as though the wiring harness to the trans may need to be inspected to be sure it is in good order and the connections are seated firmly.
I am assuming the transmission is not the issue.
I am thinking maybe a branch or something snagged a wire harness and jiggled it loose maybe?

My f350 w/v10 has a serious loss of power from a standstill. The engine will bog down when in forward gear. In reverse, I can spin the duallys. In park or neutral the engine seems to have plenty of hp. ...

You can spin the duallys in reverse because reverse is a MUCH lower gear. NO, there is no kickdown cable for your transmission. Your transmission is controlled electronically.
If the engine is bogging down or if the transmission is trying to start up in the wrong gear, either the check engine light should be on or the O/D OFF light should be flashing. The best course of action in diagnosing a problem with a computer controlled engine and transmission is to scan the computers that control them to check for fault codes.

Changing the fluild ( all of it) might fix it if your lucky. Something overheating sounds possible. Any cooling system problem can cause this and cleaning the cooling system and flushing out the transmission cooler in the raditor may go a long way towards fixing your problem. dity raditor and or coolant will cause this problem. I you clean everything real good and then go and drive it and it goes longer but still does it your in for another rebuild. this time put in a new raditor to make sure the transmission lasted as long as it's supposed to. It's possible the throttle pressure was'nt set right and the trans upshifts too early and therefore the transmission gets too hot cause the engine is going too slow to make good transmission pressure and the slipping transmission overheats. again even after corrected it'll still do it as the transmission internal seals are adamaged by heat and it'll need to be rebuilt again.

Leaks gear 90 oil by the throw out bearing on my 1999 ford f350 2 wheel drive dually diesel

The only gear oil near the throw-out bearing would be in the transmission and the only way to the throw-out bearing is out the transmission front bearing retainer. I would check the vent first. It's on the transmission top. If that's free you'll have to remove the transmission and front bearing retainer to check the front bearing and seal.

Have you changed your transmission oil and filter in a while? Would be a good idea to do so, hopefully you have caught this in time before it is a costly repair to you.
