replacing "93 E4OD
HI Everyone!
I bought a 93 F250XL 4X4 5.8L E4OD with 133K miles last fall. Last month While towing my Wrangler, the Tranny blew front seals and pewked out all the fluid 100 miles from home.
I am installing a remanufactured E4OD that is upgraded to 1997 specs. I remember reading somewhere that I should replace the MLPS and PCM.
The MLPS replacement makes since,going to new style with gaskets. My major concern with the replacement is how to align it. The only thing I have been able to find was a forum blurb that told me to start raised truck and place tranny in reverse. Then I should adjust sensor to center of range that causes the backuip lights to come on. Is this correct?
The PCM replacement confuses me. Can't I just have it reprogrammed? Remember my F250 is a '93. Please help me fill in the blanks so that I have a better understanding of the problems that require an updated PCM.
Thanks for your help!

I don't know about the sensor, but few people are able to reflash the EEC-IV PCMs. The Prom is not electronically eraseable and should be replaced with an EEPROM or you need to use a hard chip attached to the J3 port. Which is why it's commonly suggested to replace it.
