What type of noises that seem to emanate from the converter, but do not change, could indicate transmission front pump problems?

• A. Clicking
• B. Whining
• C. Grinding
• D. Hissing

Answer: (B)

A constant whining sound coming from near the converter area points to the front pump inside the transmission. The front pump is continually running to generate hydraulic pressure, so when its bearings or gears wear, it often produces a high-pitched whine that stays the same regardless of engine speed or gear selection. That steady tone fits a pump problem because it isn’t tied to shifting or valve actuation. Other noises fit different issues: a clicking sound usually comes from valve-body actuation or detents, not the pump; grinding indicates metal-on-metal contact in gears or clutches during engagement; and hissing suggests a pressure leak or vent noise. So the persistent whine best matches front pump wear or failure.
