Ford F-150 Screeching Noise After Engine Replacement

Vehicle: 2008 Ford F-150, 2WD, V8-5.4L, Automatic Transmission/Transaxle

Mileage: 172,556

Problem: This F-150 was originally brought to the shop because the engine was producing excessive vibration and internal noises. The shop installed a remanufactured engine. Soon after starting the replacement engine, it began making a screeching noise from the bell housing/torque converter area. After running for 10-15 minutes the noise stopped. Upon restarting, the noise returned and lasted for about 10-15 minutes, then stopped. It didn’t matter if the engine was hot or cold.

The technician was just about to remove the transmission to diagnose the noise but decided to call ALLDATA Tech-Assist first for some advice.
