hey im new to the forum purchased my 2001 dodge ram 1500 4x4 about 4 months ago it has almost 40000 miles on it and everyonce an awhile when i accelerate right after i start it it seems to get stuck in 1st gear and wont move with the check engine light blinking on and off id appreciate if neone had any info on wat it might be i already had the transmission governorpressure sensor replaced

 

Could be Torque Convert Clutch solenoid, haven't heard of it messing up in 1st gear usually 3rd and overdrive. Take it out of overdrive and try it, might be the issue
