How do I change the transmission oil on my 2005 Freestar

This is probably the result of a belt / loose linkage. Linkage is the system of mechanical rods, cables, etc. that connect the gear shifter inside the car to the transmission itself. This is usually an inexpensive repair.

have the fault codes read . Check oil level in transmission (in D and hot)

Here's a link to the oil pan bolt specs.

T45 holds the rotor in place. Today was just reconnaissance on that , so i am good to go AM on my 2005 Freestar

It is under recall for problems with the torque converter in the transmission. Take it to your local Ford dealer and they will replace the torque converter and transmission fluid at no cost to you.

try topping it up with fluid first most auto's slip when low on oil

will take 5l of oil does this help make sure to put a bit of oil around oil filter gaskey hope this helps

Check the transmission fluid level. if there is none, or it is low, the car won't move. Use caution when buying transmission fluid. there are different types for different cars.

try replacing the plugs, either one is not functioning properly, or has got clogged up.
maybe a full air,oil and fuel filter change

if you want one from ford you have to go to your local ford dealership and order one in the parts department you can also try downloading one for your car try www.edmunds.com to see if you can if it was me i would go to your local napa and they be able to tell you how much oil and the type you will need wish you the best of luck Michigan Man.
