Please fill out the following to ask a question. MAKE:ford MODEL:E150 YEAR:1997 MILES:200000 ENGINE:5.4 DESCRIBE ISSUE....trans shifts to OD to quick. I usually drive with OD button set to off. If driving around town trans shifts to early and with just a 1/4 throttle if I accelerate the van shudders badly sometimes even at freeway speeds and I either push the button to turn off OD or hit the throttle a lot more and it downshifts. I'm not sure if the trans is seeing throttle position, I can on my Determinator aka genisys. I have new coils, new plugs, new fuel filter, new air filter, trans oil is red and clear not burnt smelling. Any thoughts? Can these transmissions be programmed?
