I was told that i need to get the codes for the transmission also now or these the same codes im already getting. the D4 light dont flash all the time.

Does the D4 indicator light come on for 2 seconds after the ignition is first turned on(II)(Key on – Engine Off) position?
– Or is the light on constantly while in the same key position. Either of those could me an problem.

Explain how your transmission is acting. Is there any problems besides the D4 light? Maybe flaring? Delayed shift? Is the engine operating normally?

If that light has been blinking like you said there is a Trouble Code stored in the TCM (Trans. Control Module). To get the codes you need to jump the Service Check Connector, it’s a two pin connecter up under the glove-box, I think it’s a blue connector if I remember right. I’ll write down here how Honda’s service manual says to get the codes out of the computer..

“When the TCM senses an abnormality in the input or output systems, the ‘D4’ indicator light in the gauge assembly will blink. However, when the Service Check Connector (located to the lower right of the glove compartment) is connected
with a jumper wire, the ‘D4’ indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned on.
—- When the ‘D4’ indicator light has been reported on, connect the two terminals of the Service Check Connector together.
Then turn on the ignition switch and observe the ‘D4’ indicator light.”

You can use a piece of wire or paper clip for this Larry.

“Codes 1 through 9 are indicated by individual short blinks, Codes 10 through 15 are indicated by a series of long and
short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the code. After
determining the code, refer to the electrical system Symptom-to-Component Chart on page 14-36 and 37.”

“Some PGM-FI problems will also make the indicator light come on. After repairing the PGM-FI system, disconnect
the Back Up fuse (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory.”

If you need help with the Diagnostic Trouble Codes (DTC’s) Let me know.
Take your time when you write a reply, your Original Post was hard to understand and makes it harder to help.

yes the D4 light comes on for about 2 seconds and goes off. I pulled the fuse for 10 seconds and put the jumper wire on turn the key back to on and the codes i got was 14-1-2-7-8 the trans does seem to delay a little on changing out when you first start off. Ive also noticed the rpm gage jumps around alittle when it changes. Thanks again larry

Well for troubleshooting ’14’ it looks like a bunch of electrical testing with a special harness Honda has. Saying possible causes – 1)Short or open in FAS(BRN/WHT) wire
2) Trouble in ECM

Code 1. Possible Causes:Disconnected lock-up control
solenoid valve A connector.
-Short or open in lock-up control
solenoid valve A wire
-Faulty lock-up control solenoid
valve A

2 Poss. Cause) Disconnected lock-up control
solenoid valve B connector
-Short or open in lock-up control
solenoid valve B wire
-Faulty lock-up control solenoid
valve B

7)Disconnected shift control solenoid
valve A connector
-Short or open in shift control
solenoid valve A wire
-Faulty shift control solenoid
valve

8 ) Disconnected shift control
solenod valve B connector
-Short or open in shift control
solenoid valve B wire
-Faulty shift control solenoid
valve B

That’s a long list. And they have troubleshooting tree’s with electrical tests with special tools or a Electrical meter that’s too long to type out. It looks like a lot of the possible causes are electrical connector stuff. Take a look at your shift solenoids connectors and wires if you know where they are. Make sure everything’s connected properly. Sometimes just disconnecting and connecting a connector will actually fix the problem with an electrical item (I’ve seen it first hand)

You may have to bring it to Honda. Have you ever had your Exhaust Gas Recirculation system worked on? I know they have problems with those ports clogging up with carbon on those cars..
