6 Speed Torqshift?

OK, I found this:http://home.austin.rr.com/sbv1/Procedures/TorqushiftShiftRelearningStrategy.htm

Why would Ford advertise the TorqShift as a 5 speed if it's really a 6 speed?

they will probably re-use the same transmission in the 2007 models, and extricate that extra gear and call it a 6-speed. the torqshift only uses 5 gears ALL THE TIME, therefore it is a 5 speed, and only a 6- speed on deceleration if ia can remember correctly

It was explained in a previous thread that "PSD 60L Fx4" replied to.

In OD mode, 6th gear is your "OD" gear and in Tow/Haul mode, 5th is your "OD" gear.

I have to find the thread - but I believe it has 2 4th gears - that differ slightly in ratio.
Depending on whether the trans is cold or not, depends on which 4th gear is used.

Actually, I just looked at that link you posted - it explains it better in there than what I can.

Exactly.

When cold, instead of using the direct drive clutch (the weakest of the clutch packs) for 4th gear, it utilizes the intermediate and overdrive clutches to obtain the1.090 drive ratio mentioned in the link(instead of a 1.000) to reduce wear on the direct drive pack. If you'll notice even when warm, the 3-5 upshift is certainly the sloppiest- thanks to both the smallest clutch pack, and an inversely proportional shift solenoid.

Intersting... I actually counted shifts today and I counted 5 gear changes from a stop. And yes this occurred when running at normal operating temp.

The slow "shift" between 4th (5th) and 5th (6th) is converter lockup.
