I am the second owner of a 1999 Ranger XLT 4 cyl with 28,600 miles and Ford factory rebuilt 4R44E transmission (about 8000 miles) with 1-2 shift problem. Original transmission failed after time warranty expired and original owner had it replaced. Local dealership will not honor transmission warranty since I am the second owner.
Under very light acceleration at low speed the 1-2 shift does nor occur until 20-28 mph. After it shifts, many times it immediately downshifts to 1st and may stay in 1st to over 30 mph; other times it may shift 1-2 hard at about 25 mph and then immediately shift 2-3. Under normal acceleration it seems to shift ok or slightly hard at about 15-17 mph.
Fluid, filter, and 1-2 shift solenoid have been replaced by Lincoln-Mercury dealer technician who says "everything checks out ok" but I just don't belive it's right. Fluid level is correct to "hot mark"; speed sensor must be ok since ABS, cruise, and speedometer work normally; No "Check engine lights"; and no unusual transmission vibrations or sounds--just the annoying 1-2 shift. My Taurus and '83 F350 shift much better. Has anybody else had this situation or have any ideas about the cause or a fix?
Thanks,
Ken
