Problem with my renault megane

l Change the speed box that was automatic to a chisronica and now do not turn the vehicle and show the anti -boot system on the screen of the tacometer that I can do help

The car needs the point signal or parking of automatic change to start it, if you have changed the gearbox for a manual, I do not know what you will have done with the cables.

Anyway, I don't think I can be much more help, you will have to examine the hoses and determine which cable you have to bridge to start the engine. O Reprogram the switchboard with manual change software.

All the best.
