First check under-dash Fuse No. 25 (7.5A).

If it is blown, there should be a spare 7.5A fuse in slot no. 35.

i checked the fuse and it intact.

Check the battery cables and terminals to ensure no corrosion, cable wires frays, and tight connections. If necessary, remove battery cables, clean cable terminal with a wire brush or something, and reconnect. Generally, negative battery cable should be removed first and re-installed last.

ok i will do that thank you... after that is done my transmission will unlock?

If the cause is due to a poor ground (-) connection, then the issues may go away. Otherwise, no.

if that is not the problem what could i do to fix this problem?

You would need testing tools like a multi-meter to do some diagnosis; checking voltage and continuity at wires, fuses, components, etc.

Alternative is to have someone with some testing tools and automotive knowledge to check for you.

ok thank you...so i just have to keep unlocking the gearshift manually until i can get a reading done.

Check the battery connections (visually, etc.). Make sure the cable connector is pushed down all the way on the battery terminal and properly tightened. If that is the cause, the issues will go away.

A 10mm wrench or adjustable wrench is all that is needed for the battery cable connectors.
