2000 7.3L Auto Wont Shift into 2nd

[njk4o5]

Having some trouble with my truck. I have a 4 inch turbo back, riffraff intake, and dp chip. the other day i had my truck in 80econ mode and i ripped on it from stop. when it wnet to shift into 2nd, it kind of missed and then finally caught.

Now the truck will rev out to redline before it will shift into 2nd. Whats wrong with my tranny?

you need a new one lol

i suggest if your going to "beat" on it get a built trans..

Could be a TC failure.

mine did this... pretty sure it was the TC

dont make the same mistake i did though and put in a PI Stallion TC... it completely killed the tranny, BTS on its way

I had a similar failure but mine was a messed up spring in the valve body for the shift to second gear.

any idea how much that spring would be to fix? could i do it myself?

i was reading up on howto change the valve body and it seems i would be able to do that myself. anybody know if that spring would be easy to swap out? truck shifts nice and smooth from 2nd to 3rd and so on. its just that first shift from 1 to 2 that it needs to redline before shifting

Well, when the spring ****ed itself on an angle I decided to buy a valvebody that was modified and throw it in.

I found out the spring was bad by pulling the valvebody. Drain the pain, drop the pan, remove the filter, unbolt the valvebody. It is messy, but very straightforward.

how you like your VB? does it get rid of the shift/tq lock indecision around 35 or 40mph?
