4.6 is transmission problems

[colin1892]

Long time lurker on here, but first post.
Apologies first off if this has been covered elsewhere but I couldn't find an answer.

I have a 2003 4.6 is.
My transmission totally shit itself and I've just paid an independent firm £3200 to have the transmission and torque converter reconditioned.

Prior to the problems, if I was driving in manual mode and slowed down at a junction, the gears would only shift down as far as 3rd and stay there.
This problem still exists after the overhaul.

When driving in auto (not sports mode), when I approach a junction there is a very annoying and sometimes violent jolt when the box kicks down to 2nd and 1st gears.
This was a problem before and now after the overhaul.

Anyone with similar experiences?
Any advice would be greatly appreciated.
