update: i got the 97 trans into my expedition last night and took it for a test drive and it does the same thing as the one that came out . It goes to shift into third and just revs out. The trans i took out had a damaged ring on the 2-3 accumulator piston as well as the sprink broken into...
So i was having issues with my trans like it was going into neutral when shifting from second into third and just revving out. I changed all the electronics inside fluid and filter and nothing changed so yesterday i took my expedition to my buddys house because he said i could have a trans out...
this is the print out i got when i had the code read at autozone:
P0743 it says the ECM energized the TCC solenoid and detected no voltage drop on the circuit
I dont know where i got the P0740 code from
thank you for the info so far today i unhooked the tps msensor to see if it made a difference and it just made it shift harder between 1st and 2nd still no 3rd or 4th. i also tried running a jumper wire from the harness connector uptop down to the connector on the trans for the tcc solenoid the...
the truck has 152,000 miles but i'm not sure if its the original trans. there is a light blue sticker on the side of the pan reffering to service exchange. the fluid don't look bad and it doesnt smell burnt. before it quit shifting into third altogether when third engaged it would shift into O/D...

i have to drive around in 2nd gear because when it goes to shift into 3rd it revs out like neutral and i have to push the O/D button to keep it in 2nd. it started out where i had to let off the throttle when it would go to shift into 3rd and let the rpms come down and then it would engage and...
Ive been reading through some of the posts on here trying to diagnose a couple problems. I just recently purchased my expedition and im very happy with it so far
i know this is a long shot but my 01 expedition is having the same exact problems and im not convinced that the tran is toast...
it started off by shifting hard into 3rd and got worse to the point where you would have to let your foot off the gas and let the rpms come down to get it to shift...
