Automatic 93 Accord Shifting Problems!!!!
I do not drive the Accord, it is my girlfriends. Its got the F22A6 with automatic transmission. When you start the car and your still in park, it says on the dash that you are in park and d4 at the same time ( both lights are on ), the same thing if you put it in reverse then it says its in reverse and d4, no matter what gear your in it says that gear and d4. No one seems to know what the hell is wrong with this posessed Accord. I drove it and it seems like it starts out in a high gear like 3rd, and shifts ONCE to 4th and thats it. I dont know much about the automatic transmission so thats why I am asking. Anyone have a clue as to what the problem could be. BTW: she just had the voltage regulator in the alternator rebuilt and thats when it started this madness!
Thanks ahead of time for any info.
If I can fix this for her, were talking major brownie points with her parents!

Are you throwing any CEL's?
Have you searched on the TCU since this has been a huge problem with 4th and 5th gens.
My guess (if its not the tcu) is a tranny solenoid, refer to your chiltons/haynes/helms manual for assistance.

Re: Automatic 93 Accord Shifting Problems!!!! (b-clubspecII)
As many of you are aware, early 90's Accords regularly have transmission shifting problems (eg. S light flashing or on steady, D4 light flashing, trans takes off in 2nd gear). The most common cause of this is a burnt out TCM.
I have been rebuilding these computers for quite some time now and have some in stock ready for shipping, or I can rebuild yours.
For pricing, or more information, please email me at: cmrvi1@yahoo.com
Below is some info on how to check for codes, TCM location, and most IMPORTANTLY, how to check your TCM.
Behind the right hand corner of the dash on the passenger's side (just below the glove compartment, or sometimes stuffed behind the kick panel) you will find 2 connectors taped to the wire harness with blue tape ( unless someone previously removed the tape). One is a three wire connector (data link connector) the other is a two wire connector. By jumping the two wires on this connector, you check for engine and transmission codes.
With the ignition switch off, connect the two wires together. Have a pen and paper handy. Turn the ignition switch on. The S light (or D4 light if your car doesn't have the S light) should start to flash a code. Might be a combination of long and short flashes. A long flash stands for 10, and short flashes are 1. For example, if the light blinks: long-short-short-short, then that is a code 13. When you find out what code it is, post it and I can tell you what is going on. BTW, 90-93 Accords have a bad habit of burning out the trans computers. So sometimes you won't get a code. The light will just stay on steady when you jump the connector.
If the light doesn't blink when you jump the connector, then your TCM (transmission control module) might be bad.
To verify this, remove the TCM ( it's located under the rug on the passenger side) bolted to the firewall. You will find two modules bolted to one bracket. The TCM is the smaller of the two, on the right.
To remove it, you'll need to remove the 4 bolts securing the bracket. Then, unplug both computer modules, and gently remove the bracket.
Next, unbolt the TCM from the bracket.
Remove the four screws that hold on the cover.
Look at the board carefully. If it is bad, you will find a burnt out resistor and a leaking capacitor. Again, LOOK CAREFULLY. Yours might not be as bad as the one in the picture, and only one of the resistors will overheat and turn slightly brown. If this is the case, I can rebuild it for you, or sell you a rebuilt one.
Email at cmrvi1@yahoo.com for more details.
This is the TCM
With the connector pointing down, the bad spot will be in the lower right corner
This is what the damaged part looks like up close

Re: (b-clubspecII)
Its an easy fix...
Just go to the passenger side of the car and lift up the floorboard. After you lift up the floorboard you will see 2 boxes, the one with the window on top is the ecu and the one next to it is your TCU. Unplug the tcu and undo the screws holding the cover plate on it and see if that is your problem. If it is get a replacement from ebay, http://www.cb7tuner.com , junkyard, etc...then just replace it in the order you uninstalled it.
