I took a 4R70w trans out of a 1998 F150 4x4 with a 4.6 , I put it in a 2003 F150 4x4 with a 5.4 that had the same trans now truck will not shift. trans worked great before swapping can anyone help with my problem thanks
The trannies are the same but the electronic is different. I know you have to repin the wiring harness. I'm going threw the same swap but cant find a write up on it anywhere
been my experience that with Ford to stay within 2 years......Ford likes to change every 2 years....for example on a 1997, 98 should work, but 99 has a lot of different stuff....
If you have both trucks take a look at the data tag in the driver's door opening. There is a TR shown, and under that either a U or an E. If the same letter is on both trucks the trans should work fine.
I have 1997 4.2 v6 automatic with a bad trans. I also have a 1998 5.4v8 with a good automatic transmission. Both have the letter "U" on the data tag on the drivers door post. Will the v8 trans work in the v6 truck?
