My Honda Civic (Automatic) appears to have trouble shiftong into 4th gear
When it is on the highway it revs at a high RPM and when the foot is taken off the accelerator pedal the car slows down a lot. Has anyone had similar problems with the transmission or is this a normal occurence
Thank you

 

this may be a stupid answer, but make sure that the overdrive button on the shifter is on. Also, i thought all civic si's were manual transmissions.

 

no not all i think he is from canada our si models where (usa)EX and our SIR's where (usa) Si's

i dont know my Canadian Si is manual i wouldnt know anything about automatics .... but still even if the car wasnt in OD it sould still shift to 4th gear

 

Yep.. that's the most logical answer.
I've added a footnote to the thread title, so this doesn't get moved in error.

 

unless canada was really that special, I don't think the civics up there have an overdrive button. thats why there's d3 and d4 on the gears.

how many miles are on the car?
whens the last time you changed the tranny fluid?
are you sure you're not driving in d3? (I'd hope not, but you never know)
