Hey guys, I'm trying to figure out what Sonata V6 5-speed auto
tranny's are doing. Quite a few people (on another forum) notice that
the tranny feels like it's dragging, almost like it drops into gear
when you coast. Mind you, it's subtle, not a harsh deceleration like
an aggressive downshift.
On my car, with A/C on (dunno about off!) when I coast down from
~60mph, at first I feel no deceleration. Then, when the car finally
coasts down to ~40mph, I start feeling deceleration like the torque
converter has locked. The car then slows pretty quickly from ~40-0.
Does anyone have knowledge of how the tranny is programmed WRT the
lockup torque converter? At what speeds and gears is it supposed to
lock and unlock?
Also, the Sonata has a tricky A/C compressor that is supposed to
disengage under certain conditions. Could that be causing the slow
Here's my reasoning for that question:
*When the A/C compressor is engaged, the engine idles higher.
*When you are driving and release the accelerator, at some point the
A/C compressor may be kicking off, in turn causing the engine idle to
reduce by 100-200 RPM. That would feel like a "drag", that could be
misinterpreted to be the tranny dragging. Make any sense?
Any knowledge as to whether the draggy feeling is normal or abnormal,
and the cause?
