Has anybody had any experiences changing gears from 3.55 to 4.10 on a new f-150, mostly curious about any computer problems.

 

fordman#2,
Welcome to the F-150 family! Be prepared to start adding accessories to your truck, the msg boards are informative and also very "addictive".
I had mine changed and experienced no computer problems. Check out the msg board archives on gear changes and such, lots of good info there. Good luck.

Franksnbeans- Did you test your truck out for computer problems. My truck ran just fine until I tested it with overdrive off. started from a slow roll went to WOT and will either hit the rev limiter before it can shift to second or it trys to shift to second but real slow,soft or sloppy. Run same test with overdrive on and it shifts just fine. Mike says he can fix it with custom program....Capt.
