i have a 89 f250 with a 7.5 engine and a E4OD Trans. after towing a travel trailer this weekend it started to miss? it's like there is no power. Now when you step on the gas when it is in drive it spudders up to speed the higher the gear the worst it gets. It leaked alittle trans fluid but has since stop. i changed the fluid and filter but it still happens. is it the trans and if so is there anything else that i can do other than rebuild or swap out?
