1998 Honda Accord Q&A

1998 Honda Accord Question: What causes the transmission to down-shift roughly on stopping?

Car drives ok. Up-shifts smoothly but jerks when you come to a halt and it shifts into 1st. Mounts are ok. Replaced "lock-up" sensor but problem persists. -
Answer 1
Mounts are ok? Any engine movement when shifting from reverse to drive and viseversa? Upshift puts a different torque load on mounts as opposed to downshift! Engine will react differently. Have a mechanic test drive it. -
Comment 1
The engine and transmission mounts were replaced with genuine Honda mounts. The jerking occurs only when you come to a complete stop, not when it down-shifts while in motion. -
Comment 2
Check engine light on? Does it feel like an engine skip or misfire while stopped in gear? -
Comment 3
No check engine light. Engine runs smoothly all the time. -

Answer 2
What is the idle speed at in park and in drive? Honda ATF in it? Check level with trans warmed up and engine shut off , on LEVEL surface. Next step would be to have trans monitored while test driving. How many miles on it & is it original trans? -
Answer 3
My check engine light is on when this happens -
