studders when downshifting

My car has 77000 miles.
My car has an automatic transmission.

Hi there. If by stutter you are indicating that the engine RPM seems rough or while downshifting the transmission seems to slip in and out of a gear, there could be multiple reasons. Generally speaking, when a transmission has difficulty downshifting, it’s caused by an obstruction of debris inside the hydraulic lines in the transmission. Since the automatic transmission is a hydraulic system, it depends on smooth and efficiently flowing fluid to operate correctly. If the engine itself if rising and lowering in RPM during the downshifting, it could be due to a faulty torque converter, or fuel system components. It’s probably best to have a professional mechanic come to your location and complete a car is hard to shift inspection, so they can isolate the symptoms and recommend the right repairs.
