Transmission swap no speed work

[trinixtc]

hello i am pretty new here.. i have search all over the forums and net.. i did a 5 speed swap on my 98 eclipse... everything work except the speedometer. on the automatic transmission there is the in put and put put sensor but on the 5 speed there is 1 sensor.. the car runs great. i have not swapped the ecu as yet tough.. i looked at the wiring from the diagrams and tried joining them in all different ways. has anyone got this to work??? thanks you. reverse lights work also.. car make is jun of 98 2.0 non turbo.... thank you in advance...

It's near impossible to understand what you're saying here. I'd give some advice but I have no clue what it is that you're trying to convey.

Clean up your grammer a little bit and we'll help you out.

basically did a auto to 5 speed swap... my speedometer does not work.. i am not sure if i need a 5 speed ecu for it to work, everything else works..

I'm not entirely sure but I wouldn't say that I doubt it.

The speed sensor for a 5 speed is TOTALLY different from that of an Auto. Wouldn't be too far a stretch of the imagination to think they send/receive different signals

To get the speedometer working again, you will have to get the factory plug from the M/T speed sensor (might have to get it from a junk yard) and you will need to run the #3 pin from the harness to pin 66 on the lower ecu connector. This will be a yellow wire with a white stripe. This wire is hooked in parallel with your speedometer and should still send a pulse signal to it. the middle wire from the speed sensor should be sent to pin 43 on the lower ecu harness. This will be a black wire with a green stripe. This supplies an internal ground for the circuit. The #1 pin from the speed sensor should be run to pin 44 on the lower ecu harness. This is a solid yellow wire. This supplies 8 volts to the sensor, which is the normal operating voltage. DO NOT SEND 12V TO THE SENSOR. This system works because the auto transmission computer takes signals from the intput and output speed sensors and converts that to relative speed pluses that the engine computer and speedometer can use. Without the auto transmission, the EATX-ECM has no output to the gauge or ECU. This electrical re-wire should fix this problem. Pin #3 on the speed sensor should have a little more space between the center plug than pin #1. To restore cruise control and b able to start the car, you must hook up the clutch pedal switch. the black wire with yellow stripe from the 10 pin harness used for the transaxle range switch should be located in pin #5. This wire should be hooked up to a clutch pedal switch that is grounded while depresed.

I have the same problem with my 99 Eclipse GS .I did the transmission swap and the car is running perfect but the speedometer don't work. First thing you must do is try to get the plug connector that goes in an manual transmission (You can't use the one that you used before in your automatic transmission) The next step will be figure out were the wires that comes out the Plug connector are suppost to go... Iam doing that step right now .., If you solved the problem please help me . I know this have solution .
