My G/F purchased a 2000 legacy from my dad (he bought it new and he's retired- 85,000 miles, cherry condition always dealer serviced). Anyway, she started complaing that it sometimes hesitates, then says it shudders as she's stopping (I haven't driven it, sounded like the torque converter isn't unlocking). Anyway, she has seen the A/T temp light a few times lately, and it seems like the under hood temperatures are high as hell, although the engine isn't overheating. I did a vacuum test to see if the cat is clogged (dealer replaced recently) and it passed the test. Everything else seems normal, the tranny fluid is clean and full and no obvious problems. Any ideas?
