what would transmission not to shift in to overdrive
the overdrive sencer
My 1984 corvette transmission is not shifting into overdrive. It shifts first thru third fine.
Your transmission might automatically shift out of overdrive while driving on the interstate because of low transmission fluid. This issue might also occur because of a bad transmission sensor or overdrive sensor.
will the transmission causes my 1999 ford expedition to bog down & sputter when accelerating the 4.6liter engine.
Yes, it sure can.
If the transmission is healthy and any/all adjustments are done properly there should be no slippage.
Linkage adjust
Friction in the transmission system may cause whining noise when a car is accelerating. A poor engine or clutch assembly may cause the excess friction in the transmission system.
The Overdrive Light flashing indicates an internal transmission problem which could be caused by anthiny inside the transmission. Most likely the transmission would have to be removed and taken apart to find the problem.
Your transmission is slipping, due to either your trans. is bad or your low on fluid and there maybe a leak.
Check for a broken motor mount or transmission could be going bad.
