P0700 only causing the car hardly move but when restart it works OK even Check engine

Question

when the car is running suddenly check engine comes on screen. and after once stop it moves hardly on high rpm.
when check engine sign is there the car takes jerk on chaging gear position on "D" and on "R" but not on "N" and On "P"
when i restarts the car then although check engine sign dont disappear but car runs OK and no jerk on changing the gear position.
i already get changed the switch or sensor outside the gear box for p0705 and it runs fine for some days but again same problem
it takes little jerk while running then check engine sign comes and same code p0700 only.
this signs goes itself after one day and then comes again.
i am very upset because the mechnic is unable to understand why it is happening so. some times he scans and clear it with computer and says it will be OK but again it happens.

HI there,

This code only means there is a code stored for the transmission in the transmission control module.The code means the transmission module is asking for the check engine lght to be turned on. You need a good scan tool to read the transmission control module and check for codes.
