ORIGINAL: FASTBLACK&lt\\;br&gt\\;&lt\\;br&gt\\;The vehicle in question is a 93 F-250 with a 351 and E4OD tranny. When i put truck in gear it wants to stall. If i am at a stop light and i start to go it wants to stall. CEL will come on occasionally but doe’s not stay on. I checked for vacuum leaks under hood and cleaned the IAC. No vac leaks and cleaning iac didnt help. I dont know if this can be related, but when it starting acting up so did my speedo (jumping around) These tranny’s are known for &quot\\;rumbling&quot\\; normally a tranny fluid change or flush will fix it. I changed tranny fluid but did not flush the whole system. The rumbling is gone but the other problems are still present. I had a shop try and pull codes. The scanner came up with nothing and none stored either. Any suggestions, i dont want to start throwing parts at it.&lt\\;br&gt\\;
