weird shifting
Hello all,
So new guy here. Been lurking on this site for awhile reading. So here goes my problem. I recntly got a 2001 f250 7.3 I love it, been waiting years to get one. ive had it for about a month and have noticed that the truck seems to not shift into 4 gear. I can get it up to around 45-50 and it feels like it never shifts to another gear I get the rpms to around 2500. I can get it past that but iam afraid to push cause I dont want something to break unto I know what it is. When I let off the acceleration the rpms drop and almost feels like Iam in another gear.
The od button doesnt work on it I need to replace the whole shifter column cause its so lose so I figured id replace it all at once.
So is this normal lol? Is it going from 1-2-3- to od ? Or am I missing it shift intp 4th?
I know this seems hard tp understand so I want to make a video of it to show you guys What I mean.
Thanks in advance

Fourth gear IS overdrive. They are not two separate things. There is also a torque converter lockup in there. You are not going to hurt anything pushing it past 2500 RPM. The computer has a rev limiter that will prevent you from over revving the engine no matter how hard you try to.

Ohhh okay thanks for getting back to me.
Shoud i be able to feel it shift into overdrive ? So it should always go 1, 2, 3 into od? I just dont want to be constantly worring about it lol.
Can you explain to me whet exactly the torque converter locking up means? I have seen that alot and am a little hazy on what exactly it means.

A torque converter is a fluid coupling. It transmits torque through the transmission fluid. There is slip involved with this. At low speeds there is high slip and the torque converter will converter this slip into more torque than the engine puts into the converter. At higher speeds this torque multiplication is lost, but there is still slip. When the multiplication is lost a clutch in the torque converter engages, locking the input to the output so there is no wasted energy.
Normally your transmission will shift 1,2,3,4. Depending on the throttle opening the torque converter will lock in third gear, fourth gear, or during the 3-4 shift.
