Transmission slips- Honda accord 2001

Hi Guyz,

I too have same Problem, first let me brief about my car

It Honda accord - v4, 2002. 112000 Km

I bought the car at 75k ,at that time the car not even had the transmission changed, when i went to get my oil change done in Mr Lube, The guy advised, since it is over 6 year and 7O k, need to change the transmission oil. So i got it done/

After 104000, I started to Observe **** a bit(slipping from 1st to 2nd ) so i spoke to Mr lube guy , adviced to get the transmission oil changed, So got it done, To my Surprise, the jerking immediately stopped. I thought , I saved big bucks.

During the first time in the morning when the engine is cold, It will be soo good to drive and once i am on drive on highway and local around 30 minutes roughly, the gears starts to slip from 1st - 2nd (when the Speed is around 20- 30 km), when i apply the brakes, the car jerks( like rebound)

I went to one independent mech to get his view, He said, It might be a problem with a solenoid, which might be creating, so it can be fixed by aroung 250 -300 , so i asked him to check for colour of my transmission oil and level, he said, its good not to worry,

So, I dont know what to do ? should i try to change the transmission oil again, as i have already done around 10 k back.. or it might be problem with my transmission.

Sorry for long Letter.
My Mechanic advised to first start with 'Lucas Transmission Fix' , It might fix for smaller issues other wise better to get the Transmission fixed....
Any advice will be great help .

Thanks in advance
Dare. My 2001 Honda Accord is have a problem shifting from a dead stop. I notice that I have to rev the engine a lot higher than normal to get it in gear. The (D4) Light is blinking when I am Driving and the Check engine light is on. The auto parts store person has suggested "lucas slip and leak" juice. I am waiting to find out more. I do not want to hurt her any more than she already is. I am hoping it is not mechanical.
