Exclamation Trans Issue! Help please...

Ok so this issue happens often. As I am driving it feels as if the trans is hesitant to shift up, its almost like i have to lift my foot off the throttle for it to shift, and not in all gears, more noticable in the 3-4 shift. Im not sure why. I checked my fluid and its pink and at the proper level, no burning smells or any texture in it. It feels fine. I was told to check the TPS but not sure what to check it for... I really dont know where to start looking. I was thinking a valve body would fix it but not sure if Im right either and i dont want to start throwing $$$ at it. All input would be great.

Thanks

BTW its a 4r100 in a 2003 7.3L CCLB 4x4 if that helps.

I've got the same problem. When merging onto the freeway, especially when the engine is not fully warmed up the engine will run past 2000 and fail to grab the next gear until I almost completely let off the fuel pedal. Most days it shifts quick and barks right up through the gears when I hold the throttle at a constant level.

It's not so bad that I think there is a problem but changing the filter and flushing the fluid did not make a difference.

Do you have a chip?

PHP's tunes really cleaned up my tranny shifts, it wasn''t shifting as bad as you describe, but it does shift better with the tunes.

I'm not saying thats the answer.... just that is made my shifts cleaner and quicker.... drives much better now.

I'm curious if it could be related to your gear ratio/tire size. Do you have your speedo adjusted, with AE or anything like that? Curious if your registered "speed" is messing with your shift points.
