1748 is a" pressure control solenoid A" Im assuming thats with the tranny. How does it shift right now?

Here is another bump for ya, a tech should be along soon, sorry to hear that bud, hope you get things worked out....

[strokinford]

the line pressure in the tranny jumps from 5 to 128 at idle. and it throws this code. driving the truck really aint that good. shifts hard, early or soft and late. the line pressure is contantly going up and down. shift in and out of od. its like it has a mind of its own

[strokinford]

bump for you!

ok here is an update. i have replaced the pcm, i have continuity between the plug that plugs into the tranny( solenoid pack) and the harness that hooks up to the pcm. and the truck is still doing it. has anyone ever heard of and input sensor messing with the epc. like a throttle position sensor, cam position sensor, mlp(multiple lever position,,,i think) sensor. any input would be greatly appreciated
