If anything it's high, and yeah it's gonna be something deeper im guessing, cause whatever it is is making it stay in limp mode.

do any of these point towards my problem? im not too versed in mechanics/ could you point my in any direction?

i am having troubles with my truck shifting, it started when one morning once my trany warmed up, dropping into neutral, then when i released the accelerator, stepped on the gas again it would start accelerating again. the transmission would work fine until heated up and then start going crazy...
