Erratic decisions with tranny

[skeetdawg03]

brand new stock re-manufactured Tranny E4OD straight from ford... two months later i get a code for the sensor on the side of the tranny so i go to swap it out.. I ask for 97 f350 psd auto tranny even gave them the vin number .. the part they gave me didn't fit the plug in... took the old part in they told it was for a 95 model e40d... anyways change the part didn't fix anything...
Now tranny shifts crazy in lower speed less than 40mph... when i pull up to a stop sign it won't unlock it still keeps trying to go boggin down real hard... when i start the truck about every other time motors rpm's lope like from 500 rpms up to 1500 just jumpin till i rev it up for a sec or two the it clears up...
sometimes as soon as i put it in gear no matter forward or reverse it'll die... won't let me start it with the key doesn't recognize that its in park or neutral so i had to bypass with a starter button to the starter solenoid.....
Problem is My only truck for now and the Ford Dealerships are running three to 4 weeks behind ... can't wait that long any ideas what i can check or do .... thanks in advance for any help

Sounds like TC is locking up.....

try disconnecting the batteries for a while to reset the computer maybe that might work i had a similar problem. Do you have a programmer or chip ? turn any thing back to stock .

basically what danielkehlenbeck said............ i had a similar problem.... i tuned my TS tuner to stock position and kept acting up. disconnected it and problem fixed... I do remember being in a hurry to hook up my new chip (thus not cleaning out all that wax stuff on the pcm) .... let us know what happens...

Hey guys it ended up being a wiring problem ... i traced the wiring harness coming off the range sensor on the side of the tranny... it goes back to the transfer case splits off to another plug then it jumps across the front driveshaft .... (problem) it was hanging down on the yoke of the front drive shaft ... 3 broken wires 2 skinned out and shorted and i believe one was fine... i believe there are only 6 wires in this loom... i can't believe the thing ran at all with that many severed wires but spliced em back together taped em up tied em up out of the way haven't had a problem since... fixed the loping of the RPM's the torque converter lock up problem... the starting with the key ... the temperature problem.... seriously check the wiring start at the range sensor and work your way back to the pcm if you have too... i drove it for a year with it actin up that way took me 15 mins to fix ...

Skeet glad you found the problem! I had a 92 that did it in the rain only and it turned out the trans wiring harness went bad.
