Looking to buy a 1988 Honda CRX HF. Automatic Transmission. I would like to do a 5 speed swap on it. What is needed, how hard would it be, and what would it end up costing me?

  • Anonymous Sep 12, 2010

    Had i come on here prior to buying the car i currently have, i would have asked how much you were asking.

    But sadly i have purchased a 1994 Dodge Shadow ES 5speed.

    Not bad gas mileage, but surely not the 52 that those little suckers have!

-5 Speed Transmission

-Clutch/Pressure plate/Flywheel/Hardware

-Clutch cable

-Manual pedal assembly with same options as your car (Cruise controlLooking to buy a 1988 Honda CRX HF. Automatic - 2_bing.gif for example)

-Front, side, and rear transmission mount brackets from 5 speed car, and the actual mount for the rear (Regardless of what people say, it is not needed to drop the rear x-member to do this rear mount, but if you don't have a decent set of tools, you may have to do this to get to the rear bolt.)

-Manual axles. I think auto axles will work.

-5 speed throttle cable to match the the 5 speed pedal assembly

-Auto speedo cable will work.

-Connect the 2 larger black wires that go to the shift position switch in the automatic. These wires are for the starter. In the auto car, they are only connected when the car is in nuetral or park. Solder these two wires together and heat shrink. Use a **** connector if you want to just ghetto rig it together.

-You will get a code 19 and a "check engine light". This is for the torque converter lock up solenoid on the PS9 auto ECU (For my D16A6 Motor anyway, the 1.5 may have a different auto ECU). The car will still run and drive fine, but getting the manual ECU for you car, and cutting off the auto wiring from the harness will eliminate this issue.

-You will need to ground the Green/White wire from the shift indicator switch, this indicates that the car is in "park", and will allow you to remove the ignition key. The alternative is to swap to the 5 speed ignition switch, but you may not want to end up having separate ignition, and door keys if your car currently uses one key.

I have a HF 5 Speed ecu and a few other parts to if you need them

Price is hard to tell because of price of parts and places vary to do these swaps. Shops around here will covert a auto to manual for anywhere from 500-800 bucks labor only.

This question doesn't necessarily make sense; here's why. You said, "Looking to buy a 1988 Honda CRX HF. Automatic Transmission. I would like to do a 5 speed swap on it. What is needed, how hard would it be, and what would it end up costing me?".....but what you should know is that the HF did NOT come with an automatic transmission - it was never offered on the HF model. Perhaps you found an HF that someone swapped an automatic transmission into?! More likely than that, you are probably looking at a DX model, not an HF model. The DX is still a 1.5 liter, but the injection is completely different. If you want an '88 CRX HF 5-speed, I have one for sale. It gets every bit of the 52 MPG that the EPA estimates boast for gas mileage!

Find someone that wants a stick shift and trade with them. You're talking too much money for the result.

1991 crx wont shift after driving awhile turn it off for awhile and its fine again

im assuming this is an automatic. Provided that it's full of tranny oil, you may want to try changing the transmission oil and filter. If that doesn't do it, you could try changing the shift / speed sensor.
