Hey guys. Im asking some help here to fix my transmission.

my car is a Fit 2007 with automatic transmission.


I dont know where to start. the first problem I had was my speedometer to act weird, and the D on the dashboard was flashing. and the gears was hard to shift. sometimes the transmission downshift in first gear it happen on the highway at 50 mph the transmission down shifted in first gear for no reason.. the front wheel locked it was REALLY dangerous.

the tech at Honda told me most of the times the pressure switch are faulty and there is 2 and they are the same P/N. I bought one and replace the one in front. test drove it and nothing change. so I decided to remove the back one and replace it with the one I removed in front (used) it went fine for 10 minute and the same problem occur.

I have multiple check engine

P0722 ( first one to pop ) output speed sensor circuit no signal
P1747
P1780
P0752 Shift solenoid A stuck On
P0757 Shift solenoid B stuck On
P0762 Shift solenoid C stuck On
P0767 Shift solenoid D stuck On
P0746 Pressure control solenoid A performance stuck Off


Im guessing the problem is maybe the speed sensor ??

thank you very much

 

Sounds like the speed sensor failed or the wiring to it is broken somewhere. Find it and make sure the wiring isn't chewed up/broken. If it's not, give a new sensor a go and see what happens.

 

First check wire at harness connector 8
if OK check connector at PCM (computer) due to the multiple codes

 

I finally found the faulty sensor it was the output speed sensor #11 on the diagram I did replace the other #12 they are cheap at the dealer 27$ each ( in Canada).

the transmission is strong as hell.. downshifted in first gear at 50 mph it was really really hard on it . front wheel locked.. and after the sensor replaced still shift smooth.


thank you doctor

 

Thanks for update!
They are very valuable to forum users!

 

Hi. I have a Honda Fit import from Japan with VIN num GE61010198 (L13A engine).

Transmission has been very harsh lately, speedometer malfunction (stuck on 0 or moves like it's stuttering)... Diagnostic check threw a PO752 code. Shift Solenoid A stuck ON. Someone adviced to check and clean the 'transmision filter' and change gear box oil first. But I can't seem to find the transmission filter. Does it have one?

 

Yep, it does, or at least the US model does:

Can't remember if you can look for/see it without pulling the battery and tray.
