i think when it shifts quickly it should be ok. Unless when it shifts too slowly.. then u might have a problem. Cos i had the problem of the gears shifting too slowly in my D16 previously. Besides that it was having problems reversing when the engine is cold. In the end i opted for a B16 half cut. Now its shifting normally. :)

what engine u use now b16 auto/manual

 

[VanGogh]

I'm using a B16 auto now . By the way, I'm just curious. Are you using a B18C Type R engine mated to a auto tranny? Is it possible? I thought Type R comes in manual. Would the ECU match the gear ratios in the auto tranmission? I hope someone else can also enlightened me :)

i'm using b18c gsr blacktop auto not type r taken from db8 halfcut.
u not hear this engine before?

 

[VanGogh]

Oh I see, but if you're using the same gearbox that came with the B18C its should be normal. But what does your mechanic say about this? Its rather odd when u say it changes too quickly. Maybe some other forumers can advice us on this?

 

[civic18c]

using b18c auto gearbox also same problem that why i change to ek4 auto gearbox to soft this problem but wrong they got same problem.

 

[VanGogh]

Hmm.. maybe you can try driving a fren's or anyone's car with a similar set up to see if this quick transmission change is an 'isolated problem' you're facing or if its normal? :) Just my 2 cents...

bro..its not advisable la to flushh to frequent....ATF chg normally evry 20K max according to the manual, flush if possible evry 3 time chg ATF (60K) according to what i've read la...correct me if im wrong....use only Honda ATF other brand dont know how cos never tried...:D:shades_smile:
