I got a transmission put in my truck but the transmission came out of a 2004 mustang is that compatible with my old transmissions. My truck wants pick up speed seems like it hesitating and skipping every time I smash on the gas want go over 30mph.
( 5R55E ) automatic transmission with the 4.0 liter - V6 ( OHV and SOHC )
Which is same as V-6 Mustang.
( 4R70W ) automatic transmission with the 5.0 liter - V8
Which is the same as 4.6 Liter Vb Mustang.
The only change came in 2005 when the, "Sportmatic" semi-manual shiftstick transmission changed the configuration. So, from 1996-2004 the transmissions are the same.

You should use the torque converter and flexplate that comes with the mustang transmission. Don't use the old one as it is contaminaited with particles from failed parts. Also the parts are broken in together so I would reccomend using the whole mustng flexplate converter and tranny together.
