Trying to diagnose transmission problem. Went on a 800 mile trip, couple days after, have to press gas to engage gear. Same for all gears, does not move until i start pressing the gas, increasing RPM's.
Do you guys think this is a computer problem or mechanical??

Any help is very appreciated!

EDIT:
Just got the evil Neutral blinking, after i went to the gears manually while driving. Also got a check engine light, i went to get the codes read, PO760 and PO755 shift solenoid B and C

I did a bit more reading, the sensors seem to be under the valve body cover(is this just the pan?), anybody know how to and where i can find it??
