Hi I have a 04 civic and recently had the transmission acting weird it started making this jump when you slow down at a red light only but when drive a little faster its normal another thing is the little colourd lights (which are the N, D, & D3) on top of the odometer are all on at the same time and the D light blinks plus when all this happened the engine light came on so if any one knows about this problem I would appreciate if he told me is it worth to fix or sale and if worth to fix up to how much would it cost , and how to fix it thanks

Check for codes by attaching a code reader to the data link connector under the dash.

It's worth fixing since the Civic is not very old. These cars will go 350,000 miles, if taken care of. Start changing the transmission fluid every 24,000 miles or 2 years, as Honda recommends. This link may help:
