1990 Honda Accord EX
Automatic transmission
195,000 miles

I'm getting clattering/chattering/whirring from the transmission only when it's in PARK OR NEUTRAL. It quiets down when in gear. It shifts through all the gears fine.

It does jerk a little when in gear and I've got my foot on the brake. It feels like something is slipping or grabbing.

I just had the fluid drained and filled.

Would this be a symptom of faulty or dirty solenoids, TCU, NM or NC sensors?

Any ideas?

Thanks

 

If this has already been covered can someone point me in the right direction on the forum. Thank you
