4L65E problems. please help

[maggs6288]

i have an 05 silverado 5.3l with 4l65e. i just had the transmission rebuilt for the second time in 3k miles. the first time it was built the junk monster transmissions converter came apart and took out the tranny. i got my new tranny and converter. got it all together. drove for about 20 miles and all of a sudden its stuck in first. i have tried everything i can think of. i check all electrical. its getting voltage to all pink wires for all solenoids. changed the filter and the manual pressure switch. any help or advice would be great. also hasd my tranny guy speak to transgo and they only said to check power to tranny. i have hpt so anything i can try i will. thanks for any help in advance

start out by checking your tail lights, if the brake lights are always on then you have no power to the transmission. Check your fuses to make sure none are blown. Make sure your grounds are good and tight on the back of the engine and tug on the wires, pulling away from the ring terminal to be sure the ground wires are not broken internally inside the sheathing. Verify that your fluid level is full with engine idling on level ground.
