I have a 2001 Accord EX V6.
When the trans shifts into 2nd gear its very rough.
When from a standstill I move the shifter from N to d2 it jerks the engine.

What's the problem?
Any help would be appreciated...

 

The Trans is the problem; they had extended warranty that has now expired.
2 ways I used to test them at the auto auctions. drive along at just above idle speed and lightly step on and off the gas; Listen for a differential growl.
Next put the trans in neutral, hold the brake, bring the RPM up to 1500 then quickly shift to low; Trans will KABLAM into gear.
