Conversation Between jk080 and jdog771

The fact that it shifted into neutral tell us the shift solenoids worked but the internal components can't hold. The loss of third and forth would indicate a failure with the direct drum inside the transmission, the loss of just forth would indicate a problem with the band.

i had the code read and its p0740. i went and got a new tcc solenoid and checked the harness that runs along the passenger side of the truck and it wasnt burnt nor did it have any damage so yesterday i replaced the shift solenoids and the hard plastic wire harness and it still does the same thing. there was no metal shavings or debris in the pan when i took the pan off and the fluid is not burnt. i dont know if a seal or o-ring in the valve body might be bad but im not convinced that the trans is toast

hi im hoping im not bothering you but ive been researching for 2 days and im not sure where to go next. when my truck shifts into 3rd it hits neutral and i have to push the O/D button to turn the O/D off and i can drive in 2nd. it started off when it would go to shift to 3rd i would have to let off the throttle and let the rpms come down and then it would engage and be fine until i stopped and then i would have to do it over again until one day i left a stop light and it quit going into 3rd all together. the O/D light does not come on or flash only the service engine light does.
