Ford Tranny woes

[FORD FLARESIDE]

...need help, I have an E04d in my F150, and for some reason in low range it will not shift through the gears. I can manually shift 1st to second, but when I shift to Drive it goes right back to first.

The wierd thing is that it works fine in high range............any suggestions?

bump,...........does anybody know Fords, Or do I need to sell it and buy a Jeep?

I will check the books. It may be a faulty EPC in high range it has enough umf to switch the gears. But when in low and it calls for it quicker the solenoid may not be able to keep up with the quick upshifts.

That makes sense.......................
I probably should have mentioned that I put about 3 grand into this tranny about 10,000 miles ago. It does have a shift kit and lock up torque covertor now. (if they could be part of the problem)
Supposedly the solenoid pack was replaced last year, but I cant verify it because I did not get the old one back from the transmission shop.

I will get the meter out tomorrow and start checking things.

wow, for $3000 you should have bought a box from http://www.brianstruckshop.com/

Only thing I can think of it low line pressures through the VB.

.....the cost was in the Planetary gears. I didn't put the aluminum ones back in. I paid extra and put the steel ones in with the 6 outer gears vs. 3 outer gears stock. I didn't want to have to mess with the tranny again, go figure..........

I took the Flareside across the gravel pit today in Low Range, seems to shift through all the gears now. All I did was unplug the wiring harness at the tranny, spray some cleaner in it, and plug it back in.

Could just corrosion on the terminals cause this situation?

If this is the case, I think I'm going to shrink-rap all of my connections.

Yes, pull it back off and put di-electric grease in ther and make sure it snaps together when plugged in.
