A couple hours ago when I started up my car my D5 light kept flashing and won't remain a solid green light. My check engine light has been on for a couple weeks for a P1457 code which is the Evap Emissions Control System leak. My question is why is my green D5 light flashing? Even when it is in park the light still flashes. Am I low on transmission fluid or is this a serious problem? Thank you.
1.- Trans is on LOW ATF
2.- Trans is HOT (High Temperature)
3.- Trans has detected an issue in itself which would send an OBDII Code too.
Check your Computer if there is No Trans related code then your trans Temp is rising which could be because of low ATF or high load.
Since you are asking if you are LOW on transmission fluid it must means you don't know how to check your ATF Level.. You should check this ASAP! Because LOW ATF = Burn Trans = In most cases insurance totaled car.
do you see any atf on the ground where you park?
does it shift funny?
Do you have an owner book? it has the exact directions for your year
Level needs to be BETWEEN the 2 dots, not at either when ck- in between
Many things on the TL are not like other cars~
NOTE!!!!!!! USE ONLY Honda DW-1 fluid,,some atf will kill the trans- dextron is one
Some that say compatible with Honda may be used in an emergency- then get it on the dw-1 fully with the simple drain and refill called a 3x3
we have diy's on that
trans leaks usually come from bad seals where the axles go in
and welcome to the forum, this is the right place for answers, We have millions of miles in the TL between us,,one moderator has over 650,000 Miles on his 00TL
how many miles? history of trans fluid changes? driving symptoms?
any clutch slipping = rpm revs without additional forward speed- when shifts from 2 to 3 on full throttle-- like getting on the freeway?
stop by a parts store for a free code reading, we can get the correct fix,
codes are CLUES not a diagnosis in themselves
You can clear the codes and reset the ecu- see if new info comes up, by removing the CLOCK fuse on passenger end of dash for 1 minute, then reinsert, Its the secret backup power for the ecu = engine control unit

I have plenty transmission fluid in my trans so that's not a problem. My engine does not overheat. My car has around 134k miles.

134k miles, I have an automatic but my trans runs completely smooth.
so you have NO slippage on hard automatic shifts from 2nd to 3rd? that's good!
take a 3 ounce sample of the drained atf and send to blackstone labs with 20 bucks for a mass spectrograph analysis of the fluid and its contaminants
That will tell whats going on inside the trans
Have you ever changed the fluid?
WE all have an automatic TL, unless you pulled trans and dropped in a CL-S engine and trans with 6 speed !
Plenty of fluid,,does that mean it reads correctly between the dots= when ckd per owner book instructions on fluid temp, cold or slightly warm with specific drive instructions?
too little and too much are really bad,,have you added fluid to it, what type exactly?

There is too much transmission fluid; it is above the two holes that the level of fluid should be at. How do I fix this problem?
ATF When the engine is HOT:
Dipstick will show Level between Mid and Upper Dots
ATF When the engine is COLD:
Dipstick will show Level on the Upper Dot.
If you have too much you will need to drain a bit when Cold until the Dipstick show at the upper dot.

My car was sitting for about 5 hours before I checked the transmission fluid. I did not turn the car on before I checked the fluid so my engine was cold. So I should drain the fluid until it sits between the two dots at the bottom of the dip stick? Is there a valve or some way I could drain it?
You should drain when cold until the dipstick shows at the TOP DOT! Use the trans ATF Drain bolt, just open it slowly and allow some ATF to drain.
Imagine a glass with 1/2 of oil, If you spin the glass the oil will raise with the centrifuge force and stick to the walls of the glass making the apparent oil level lower than 1/2 (HOT ENGINE) when you shut down the car the oil can slowly go back to the base and the level of oil will stabilize again making it 1/2 again (COLD ENGINE).
This is what happens in your trans too! When the Trans Spins it splashes the walls of the trans effectively lowering the level to between the upper and lower dot of the dipstick. When the car is cold the ATF is leveled and the dipstick will show its full in the upper dot.
go by your owner book spec for cking the level
If its too high someone has added fluid!
remove by simply unscrewing the plug with ATF stamped above it, under trans
takes a 3/8th inch breaker bar/ratchet the square fitting goes into it
May need a leverage/breaker bar since its been there a long time!
29 foot pounds is spec torque, same as oil drain plug

So when you say "the dipstick will show its full in the upper dot" you mean the upper dot at the bottom of the stick, not the dot all the way up at the top?
Yes the upper of the two that are toward the bottom of the stick. The difference between the upper and lower dot is about .5 Qt if I remember correctly - this transmission is sensitive to the amount of ATF in it. Make sure you get the right amount in!
Check the ground strap attached to the transmission case. It will probably be green in color due to oxidation. Mine decided to snap off on the highway and leave me scratching my head as to why the car seemed to be in neutral. I'll try to snap a pic later of exactly what I am talking about. If you locate your trans dipstick, it is in the same region towards the radiator.
Excellent post benfour01 = the kind of real world problems others need to know about!
There is also a newly found prob with main battery neg cable coming loose INSIDE its connector at body- under the battery box
The connector itself will appear attached, but wiggle the cable inside the crimped part ,,ooops!
Also ck the 5 braided ground wires from frame to engine parts
Cleaning grounds makes the car run better- its that simple!
good grounds make for good signal to the ECU
that will make it shift funky!! Who is adding fluid to your trans??
and what type fluid = EXACTLY what did it say on the bottle?
When I bought this car in December of 2014 I had a shop do a check up and make sure all the fluid levels were okay. Don't know why this is just now becoming an issue. If it shifts funky it is not really even noticeable to me, it stills feels like it shifts fine but it could be a little funky.
should shift like butttaaaah Ck receipt- if they added fluid, which they probably did not knowing any better
and it wont be Honda dw-1 fluid=
its time for you to learn the 3x3 atf fluid change-out
also change external atf filter, its a spin-on similar in looks to engine oil filter but has its own part number --and more expensive of course!
