2000 honda preludeautomatic transmission
Sorry that I don't have the exact number, but transmission repairs and replacements are always expensive. Expect mulit-thousand dollars, or even a whole transmission swap. It might be worth it to just get a new car.
It's probably not so much the cost of a rebuilt transmission , anywhere from $800 to $1500 , but I've been out of the scene for a while - But the labor that a garage will charge you , It's an all day project , at least 5-6 hours at whatever the garage charges an hour ( $70 - 120 per hour) Call around parts stores , call a Honda dealer also , it might be discontinued but maybe there's an interchange between years . I would not trust a junkyard or used one that much, unless you have it looked at by a mechanic .
The most important question then becomes - do you like the car and plan on keeping it for several more years? or are you ready to trade it in? If trade in within next two years is the plan then find a junkyard transmission, get it installed and cross your fingers :) If you intend to keep the car for longer then the expense of having the transmission either replaced or reconditioned by a highly qualified transmission service facility makes financial sense. Get Estimates! On any major repair I recommend that you get 3 or 4 estimates from local service facilities unless you are lucky enough to have a shop with an absolutely stellar reputation available. Compare the estimates and choose one of the middle estimates. My reasoning for this is the low estimate either left something out or worse is deliberately giving a low ball estimate to get you in and then when your car is all torn apart they find all sorts of critically important things wrong with it which run your bill through the roof. Do the leg work and be an informed car owner. No reliable technician or shop will give an estimate for repair site unseen except as a budgetary estimate which will be a range from the middle average to the unusual high end possible.
