Hello great guys,this is my first time here and i need d experts in the house to help me on this:
I just noticed recently that my Honda EOD 2004 jacks and enters gear 2 abruptly,especially when i am on speed.
This occurrence has become frequent and its always when transmitting frm gear 1 to 2.
Any explanation/suggestion as to wot could be wrong will be well appreciated.

I recommend you run a scan on the transmission but before that check the transmission fluid condition

Ist thing to check is always the gear oil.
1. Is the oil low?
2. Is the oil high?
3. What is the nature of the oil?
4. Is the transmission honda recommended?

Change your gear sensor, dat is de problem

all d above is a good way to go.
u could also check ur engine mounts espesially d big one at d rear of d engine. most honda transmission issues start with failed engine mounts.
u cld check them urself, open d engine bay, engage the parking brake then engage the reverse gear then check d mounts if they are broken u cant miss it. another way is to ask some one to look if the engine moves while u engage d drive or reverse gears.
if ur mounts are ok den definately u've got a tranny issue otherwise the mounts may be d culprit.

dail this code :436HVBDS656 and see on ur fone becos u feel good

OP, 1-2 shift does not happen when you are speeding. Scan the car.
