I hav.e an 1.5L i4 engine with 6-speed transmission. On a cold start when placing the transmission in to drive, there is a hard "clunk". This doesn't occur again after driving for a while. When the car sits for a few hours or more it re-occurs.
I had engine mounts replaced with little improvement. Now I'm suspecting the transmission. I'm told this is a sealed transmission so can't check fluid level. However, someone else suggested there are plugs on the unit for drain, fill, and level check.
Does anyone have suggestions on what's causing the symptom? If it is the trans, is there a way to check fluid level or pursue other optionss.
