99 cummins overspeed
 

My buddy has a 00 cummins and it threw a P0219 CKP sensor overspeed signal. i found out why.

It has a built HTS trans in it, drag comp, FBD 240hp injectors, and a II silver 66. It pulls hard 1-2-3 but right as it feels as tho it is about to shift to O/D it falls flat on its face and i seen the tach go to 4K.

I have no clue why it is doing it. it only does it 3/4 throttle or higher.

Any asistance will be appreciated.

If you have questions and dont want to type, give me a call 484-880-0999.

Thanks guys

:humm::humm:

confusing isnt it. me and him raced last night on the way to montana west, and he had to keep lifting when at WOT so it wouldnt red line...


hopefully someone has some idea....

thanks

Sounds like the converter is slipping.
