Just had cooling system flushed, new radiator cap, new thermostat, pressure tested (OK), new trans fluid with pan dropped and filter cleaned, new synthetic valvoline oil. No leakage from water pump, 50/50 mix, and cooling system is circulating. Car overheats in 3 miles and can't be driven. Runs great, starts immediately, good gas mileage (24-25 on hwy).
Any ideas.
