[shamzil]

just need one clarification.if we change the gearbox of a gp1 does it need to be computer programed for it to work.i recently met with an accident and the garrage they were repairing had the gearbox changed and now they are telling after replacing gerabox have to computer programme it for it to work.

Should come to factory settings/programming even if the battery was dis connected.

Ask your grease monkey to shut it and drive into the sun set.

The transmission that comes on the GP1 is probably a unit that's shared across many Honda (and maybe even other makes) models. Although the hardware (the physical transmission) is the same, the software (transmission map) is different between cars because the engine, weight and performance of the cars varies. Therefore the same transmission is used with different maps. So programming (or remapping the TCU) might be necessary. 

Note that if the replacement transmission is from a GP1, then the factory map matches with the car, so remapping isn't required.

So your garage is doing one of two things here:

1. They really know their stuff and have used a compatible transmission and intend to give it to you with the factory map for a GP1. 

2. They have messed it up and buying more time by telling you stories.
