Trans Question
this is about to bug the heck out of me and i check it about 5 times a day when at a comlpete stop and accelerate at a regular speed so you can hear every shift with the OD off it will shift 4 times 1st,2nd,3rd,od then push the OD button and it will shift again i got a 2003 F250 CC LB 2wd and it is shifting 5 times is there a auto that has 5 speeds theat a previos owner could have installed
thanks

no, some of the "shifts" you hear is actually not due to the transmission shifting, but rather the Torque converter locking up, in the same gear. i believe the transmission follows this shift pattern.
start out in 1st, unlocked
shift to 2nd, unlocked
lock TC in 2nd
shift to 3rd, TC locked
shift to OD, unlocked or locked depending on the load and throttle position.
i know on my truck with the aftermarket tuning, it will go from 1st unlocked and shift into 2nd with the TC locked all the way. that is only on a moderate to heavy throttle input. light throttle, it acts normal.

Once I get the money I will be calling Jody and getting the chip that locks it up sooner, I figure it will be less wear on the tc that way as well.

my truck is so much more fun to drive now that i have full control of my torque converter. since i have added the lockup switch, i basically have an automatically shifting manual transmission. next on my list is a 6.0 converter, so i will have less of that CVT feeling in 1st and 2nd gear when the TC is unlocked during normal operation.
