05 neon. Drives fine till warmed up then goes into limp mode.drives fine after restarting for about five minutes then back into limp. Shows code p1776. If anyone can help I would appreciate it. Replaced range sensor and both speed sensors, filter and trans fluid before it threw the code.

 

Go back and check your work if it only started after you worked on it.

 

Fluid level is good (you're checking it using the proper procedure)?
