Customer Question

I just bought a 2006 ford freestar. The transmission with new converter was installed.
The problem is that the first 2 times it shifts they are hard. The next shift is smooth. It downshifts
Fine. Will this come out of this by driving this.
What could be the problem?

There are two things that can cause this problem, the ect "engine coolant temp sensor" or the mass air flow meter. If the ect is telling the computer that the engine is colder then it really is, then the line pressure in the transmission will be to high. If the mass air flow meter is telling the pcm that it is getting more air flow then it really is, this two can case the line pressure to be to high.

I have no error code or engine light

If this was in my shop I could hook my scanner up to it after it had sat over night and see what the ect is reading. Most often the ect is the problem. The ect is not that much around $20.00 and is easy to replace.

Expert:  kalamykid replied 18 days ago.

Neither of these two problem will cause a check engine light to come on.

If I drive slow and easy it does not shift too bad, but if I give it gas it really jerks you bad
Expert:  kalamykid replied 18 days ago.

I would replace the ect and see if it fixes the problem. 90% of the time the ect is the cause.

Customer: replied 18 days ago.
Can I get back to you in a day or 2
Expert:  kalamykid replied 18 days ago.

That will be fine. If the ect does not fix this problem, let me know before you go replacing anything more.

On this ford is it called a cylinder head temperature sensor CHT
Expert:  kalamykid replied 16 days ago.

That is correct on this engine. Some parts stores still have them listed as an ect and not a cht.

Customer: replied 15 days ago.
I ordered the cht for the ford will let you know today.
I also have a 1989 corvette that went you try to start it, you have to crank a long time
Maybe use either, and the fan runs when it's cold. Could this be same problem.
After you get it running it sputters it it warms up, like the choke is off?
Expert:  kalamykid replied 15 days ago.

On your vet, try turning the ignition switch on wait 10 seconds, then urn it back off. Do this three times and then see how it starts.

Customer: replied 15 days ago.
I changed the cht and the ford freestar still shifts hard, it did not fix problem.
Expert:  kalamykid replied 15 days ago.

Do you have the 2.7 or the 3.9 in this suv?

Customer: replied 15 days ago.
Expert:  kalamykid replied 15 days ago.
