I have a 98 Expedition 5.4 4x4 with 4R100 Transmission About 200K miles.
Problem is unit wont shift out of 2nd into 3rd or 4th. Started as an intermittent problem where it would erratically shift from 2-3 to OD, then it would work fine at speeds below 55 mph, then it would not shift out of 2 at all, but when I went over manhole cover bump, it would shift out of 2, only for a short period of time.
I have a 750 code and a 741 code.
Mechanic wants to sell me a new transmission. Says there is a short in solenoid pack. I have also heard that 2-3 upshift valve gets stuck.
Anyone had this problem, or can make a recommendation other than a new or rebuilt tranny?
