What would it cost to replace the engine and tranny in a 2002 chevrolet Silverado 1500?

If you are going to sell it, consider the cost of a new/rebuilt/crate engine and transmission against what you'd get for it selling after the expense. You can pick up a rebuilt engine for around $1500 to $2,500. Rebuild on the transmission if needed is in the area of $800.00. So assume if the work is done, it will run between $3,000 and top of $5,000 depending on what the labor is. Will that increase the selling price of the truck? See what other trucks that are high mileage are going for. If the body is near showroom condition, it may bring on the middle high end. Are brakes needed or shocks or front end geometry replacement need? High mileage trucks are always suspect due to wear of parts that will fail. Since it's a "gift" you may just want to take the money without putting anything in it. Have a good mechanic look at it, test the engine and transmission. Maybe just a tune up or slight adjustment in needed. With good care, there is at least another 100,000 miles in it.

My 2000 Chevy 1500 died last year in 2018, on the interstate heading to Douglas. It has over 350,000 miles on it. How much would it cost to find a used tranny or a new tranny.

IF YOU'RE CONSIDERING SELLING THE TRUCK, I WOULD GLADLY BUY IT FROM YOU. I AM ALWAYS LOOKING FOR A DECENT RUNNING TRUCK, FOR MY COMPANY.. I HAVE A FEW OF THE SAME VEHICLES AND I CAN HONESTLY SAY THAT THEY ARE WORTH PUTTING OUT MONEY FOR, BUT ONLY IF THEY ARE GOING TO BE USED TO BRING INCOME IN.. I AM A FIRM BELIEVER IN A TRUCK IS FOR A PURPOSE ,TO EARN MONEY AND PAY FOR ITSELF ALONG THE WAY!!!

Do anyone think 1,400 is to much for a transmisson to be put in
