Question about passing gear down shift

'02 XLT 4X4 4.0L
2002 Ford Explorer XLT 4.0L 4X4 auto tranny with the brown wire mod on the auto 4X4.

I had my tranny rebuilt about 4 months ago and have about 9000 miles on it, the shop that done it gave me an 18,000 mile warranty.

When I floor the gas the tranny feels like it shifts and goes up about 1000 to 1500 RPM which I am assuming is the torque converter lock up kicking out then there is a pause for a second or so and it will finally down shift into passing gear. It makes no difference if the brown wire mod is on or off.

Before the rebuild when you floored the gas at highway speeds it would go straight in to passing gear.

At lower speeds it will kick down into passing gear but at highway speeds it does what I decribed above.

He said he updated my tranny to where it was like an 05 when he rebuilt it???

He told me to bring it in so he could check it out but I just want to make sure that it is in fact a problem before I take it to him.

Did the 05's shift like this?
