hi i have a e250 2007 with 73,000 miles and when the van its running and shift to 2 give a very hard hit i don't know if its the tranny or something else when the engine its at normal temp when its cold no hit when shift

 

A few questions first,
When was fluid level last checked ?
When was the trans serviced last, fluid and filter ?
Is the overdrive lite on the shift lever on or blinking?

 

the last time i check the level at 72000 miles

im buy that van at 71000 miles and i never change the filter.

it not blinking but when i press the accelerator to overdrive give a very hard hit in the tranny
