98 V6 Transmission
#11
Thanks a lot JimBlake for your help.
I wanted to do my homework first: find out the trans S/N, what year it is, compare with the ECU S/N to make sure no harness is missing,... and report back to let you all know.
By the way, any improvements with the 2000-2002 trans and additional electronics?
I have several options: either the new trans is pre-2000 and I just need to check the compatibility with the ECU, or it's 2000-2002 and I have to check if anything is missing and compat with ECU too.
Of course, right after that, I'll do the suggested tests and code capture and tell you guys.
Thanks for your support.

I hope this helps, and sorry for the short history lesson.

No problem, always willing to learn, otherwise I wouldn't be here, thanks for the class ;-)
From what you say, it sounds like I might be better off with less electronics... I should get the car these next days or next week and will check all this.

I don't know if there's anything really different from the 97 cars from the 98 on, versus the ECU setup (for the transmissions anyway). The 97 and earlier cars used a separate transmission ECU unit, versus a combined unit (98-on). That's really the main difference.

Up through 1997 there was a cable from the throttle body down to a lever on the transmission, so the transmission knows what you're doing with the accelerator pedal. Adjusting that cable was a bit finnicky…
Another big difference is that starting 1998 that function is done electronically.

Hi Guys,
Finally got the car back this morning.
New info :
Last time I checked, the engine ran fine and no light came on when turning the ignition on.
This morning when I checked again, the engine idle was ranging from 900-1000 to 1200 rpm going up, down, up,... Moreover, the D4 light stayed on (even though I was on Park) for a couple of seconds and then went off.
The car would jump with every shifter lever gear change.
What do you think? Do you have enough info or do you need me to run a procedure. If so, could you direct me to the best doc (I have the Service Manual and the V6 Supplement if need be).
Any advice welcome, thank you for your time and help.

Little up for this thread...
Found out that my IAC valve might be the issue for bad idling (have to check the cooling system and for vacuum leaks too).
But still waiting for your help regarding my tranny problem. Do you have enough info? Should I get an OBDII unit to try to get more codes?
Thanks for your time and help.

The D4 light staying on means a code is stored for the transmission. You can get an inexpensive obd2 code reader that should give you a code and at least a place to start testing. Poor/harsh shifting doesn't really help us pinpoint a place to start a diagnosis.

Hey guys,
Finally found some time to check with a friend... Couldn't find the OBD2 plug in the car!! It's supposed to be on the driver's side above left rest pedal, right? (98 Accord Coupe V6).
Is it possible that it's elsewhere?
Think I'm going to try to clean my IAC valve to fix idle but I heard that you usually end up buying a new one... Any experience with this and if so, any brand you would recommend? I saw prices ranging from 20 to 700 USD...
