My 2007 Fit Sport (auto, 82,500mi on the odo) just had the (D) light start blinking and the check engine light go on solid.

Drove it home on the highway and it won't pop into 5th gear even when in S mode. It just hovers around 3k rpms.

Any ideas on what this could mean?

This thing has run like a top until this point...

 

Blinking D light gives me the chills. Been there man.

It's a warning light from the PCM when there is trouble with the tranny. Usually it gets a CEL to accompany the light show, but sometimes it doesn't (those are the real troublesome problems, broken wires in the harness and such). It repeats an identity then trouble code. I once had a list to decode older versions but I don't know where it went.

Check tranny fluid. Typical honda is get it warm, then shut engine off, then check between 30 and 90 seconds after ignition off. (do an initial safety check before starting, to see if it is even on the stick.)

How many changes have you done thus far? Only Z1, not dexron or mercon or t-TIV that tend to cause bad problems?

If that's all perfect... ick. A bad lockup solenoid could cause that... or a myriad of other things.

 

lets hope the fit's auto trannies are not as bad as the

97-01 autos preludes
the second gen auto acura CLs and the early 2000-2005 TLs.

but i have a feeling the fit's trannies will be a bad one (auto)..because honda sucks in making the "shift it yourself" paddle/trannies.

 

I actually just had the tranny fluid changed by Browns Honda here in Maryland about a week ago. They did a drain and refill only, as that seems to be what Honda recommends. That was my first tranny fluid change as the fluid was starting to turn a bit darker in color.

Today, on the way to the dealer that tranny was shifting fine...going into 5th with no problem. Blinking D did not come on.

Check engine light still on.

 

get the OBD2 scanned and see wat the error is. you can read it without clearing it so the dealer can see it too.

probably something to do with the tranny fluid. could be that it's leaking or they did not use the right fluid.

 

Diagnosed by dealer as P0847 code.
Trans fluid pressure switch "B" (3rd clutch) failure.
Special order part, $54.00 plus labor.

 

so they broke the sensor and now they want you to pay for it?

 

Far be it from me to defend the dealer, but we've had a pretty nasty 2 weeks here in Maryland. I did go through part of an unavoidable large body of standing water the other day. I suspect that it is possible that water managed to get into areas they do not typically do and caused the fault.

I have no proof either way though.

I doubt that their changing the ATF a week or so ago had anything to do with my issue. I do log over 600 mi per week driving. Parts fail sometimes.

 

Glad to hear they had a direction to go in. Hope it all works out.

Yup you're correct, honda atf changes are drain (via plug with 3/8" square hole) then refill. Dunno what they say on the fit but it always used to be at 60k then every 30k thereafter (because each change only drains and replaces about a third of the system's capacity).

It's nice tho that the pan doesn't have to come off like *ahem* some cars.

 

i have the same problem..did you see where the trans fluid sensor is located sir?thanks!

 

I had a problem with a dead battery and got a boost from a neighbour who inadvertently put positive on negative terminal and blew main fuse on a 09 Honda Fit auto import from Japan. When central locking fuse was also blown - the mechanic changed fuses to correct central locking - only for flashing D to start.
