figured id start a post with just the tranny issues and not a swap.
okay,it dont seem to slip in reverse.slips in all gears.when i step down on it the truck will jump.I unplugged the connector on the pass. side of the tranny and when I did there was a noise that stopped and I tried it out,slipped even worse,would barly move.I plugged it back in and when i did I heard a click then the noise was back,almost sounded like,well its hard to describe.a slight wining,not very loud...could it maybe be a bad solenoid?

 

Do you have a E40D or a AOD?

Fluid Level:
Full?
Low?
Overfilled? (This is just as bad as low)

Has the Fluid & Filter been changed recently?

The forward Clutch Bands in the transmission may be worn
or
The Torque Converter could be bad.

-----------------------------------------------------------------------------------

Are the Throttle Cables hooked up as they should be?
The reason I'm asking;
On AOD transmissions, there are two cables connected to the throttle body,
one of the cables enables the transmission to downshift properly,
it's called TV Control Cable (TV = Throttle Valve)
and if not hooked up or adjusted correctly, the forward clutch bands will wear-out rapidly and the transmission will have to be rebuild or replaced.

-----------------------------------------------------------------------------------

The E40D transmission is electronically controlled by the EEC computer.
There are Five Solenoids which control Gear Selection, Gear Change Harshness and Torque Converter Lockup or Coast operation.

All I got!

 

i have the e4od,i changed the filter and fluid,put 6 quarts in let it warm up,stick was a quart low,put the 7th one in was fine.now it shows about a quart over full

 

scan your codes since you got an E4OD it'll give you a bit more information that symptoms and i got a book i can reference if you pull the codes(i have a trans manual for e4od's)
