H22a Auto Tcu?
I have a auto h22a setup for a fourth gen accord. I use the stock tcu for the tranny F series tranny which only redlines at 6500. I have three PON tcu's which came out of the CD SIR accord that came with the h22a. When I install them they wont shift out of PARK. But if i use the shift button on the shifting console i can shift it out of park and threw gears but once it goes back to park it wont come back out without pressing the button again...
any answers?
any answers?
i searched about a CF accord. it seems that the accords 98-01 had h22a7 in them.... what i found on wiki.
The Accord Euro R / Torneo Euro R was also in 2001, featuring a 220 hp H-series (h22a7) engine, and 'R' features such as Recaro seats, LSD, sports suspension, and titanium gearknob.

To make the shift lock operate properly you will need to run a wire from the shifter position switch to the tranny controler. On the left side of the shifter there is a box with about 5/6 wires going into it. This is the shifter position switch. You need to tap into the GRN/WHT wire and run it back to pin A7 on theTCM. Plug A is the bigger of the 2 plugs.
A little more info: On an OBD1 Accord wiring harness for an automatic transmission car, there are 5 plugs - 3 that plug into the OBD1 ECU and the other 2 plug into the TCU. TCU plug "A" has 26 wire positions arranged in two rows, one row on top of the other, each row has 13 wire positions. If you hold TCU plug "A" so that you are looking at the wires going into the back of the plug and the plug latch is pointing up, wire position A7 is on the top row, 4th wire position from the left end. The chances are high that on your Accord's wiring harness, TCU wire position A7 is empty. You will need to get a extra wire from another ECU or TCU plug. Get a wire with the smaller size wire socket crimped on to it. (if you look closely at the pins on your OBD1 ECU or TCU, you will notice that some of the pins are bigger than the others - the ECU & TCU plugs have corresponding big or small sockets crimped on the wires that lock into each wire position). The best place to get a spare plug is the junkyard. You'll probably have to destroy the plastic part of the spare plug to get a wire out - I've tried several times and could never get the socket lock to release. Take your spare wire and push it into the A7 location and make sure the socket locks by trying to pull it back out - it should not pull out. Solder the end of the wire you ran from the Park location on the shifter switch to the end of the wire you added to A7. I'm not positive that the color of your shifter switch Park wire will be GRN/WHT like the one mentioned above - sometimes wire colors change from one year to another, but I am positive that the wire you need is the Park wire.
About the JDM TCU's having the Sport/Normal driving mode capabilitiy: I'm attaching a picture of the shifter **** that came with my JDM front clip. If you also have a JDM auto transmission TCU with the part # 28100-P19-003, you probably have the Sport/Normal circuit built into it. My understanding is that when you lock in the "Sport" mode, the transmission computer raises the shift points. You can utilize this circuit by using a rocker switch or toggle switch, one side of the switch is wired to TCU wire D20, the other side of the switch is wired to ground. TCU plug "D" has 22 wire positions arranged in two rows, one row on top of the other, each row has 11 wire positions. If you hold TCU plug "D" so that you are looking at the wires going into the back of the plug and the plug latch is pointing up, wire position D20 is on the bottom row, 2nd wire position from the right end. The chances are high that on your Accord's wiring harness, TCU wire position D20 is empty. Get a wire with the larger size wire socket crimped on to it. Add the wire to D20 and run the wire to one side of the switch of your choice. From the other side of the switch, run a wire to ground(like bare metal on the floorpan). With the switch "off" you are in Normal mode, and with the switch "on", you are in Sport mode. Good luck!
