Replacing your transmission is up to you. I tell my customers who are short on cash when something major is wrong with there vehicle to think of it this way, you can spend a few thousand, and have a great running vehicle after you get a new trans or motor, or you can spend $15,000 + to get a new vehicle. But when it comes down to it, you are the only one who can make that decision on whether to keep your car or sell it. Honda's are great vehicles and have great motors, my personal opinion would be to just replace the trans, and then either keep the car or sell it for a higher price now that you have the new trans.
