Okay this will be long but hope detail helps. 1995 E350 with 446 eng. Couple weeks ago the starter went, had van towed home. Installed new starter and suddenly van would not run once shifted into gear. Starts right up but as soon as shifted into rev or fwd in sputters and dies. Gets worse as warms up. Un related changed battery and alt when changed starter as they were shot. Took it to Ford dealer and for tne sum of $185 they said tranny was bad. I knew tnanny was going as it has 200 thou miles on it. Put in new tranny and now it shakes when starting out and still stalls at lights and when shifting into gear unless you rev it up. Took it to tranny place that sold tranny to me and they said was eng problem in ign as couple cyl misfires, and tranny was a quart low on fluid so that was problem. Not. Changed plugs, wires, cap, rotor and still has problem. Any ideas oh ya new fuel pump and filter three months ago.
