Transmission Problem in Subaru Impreza

[Jzak2014]

Hello

 

I have a Subaru Impreza 1995  like look:

 

 

Problem:

When i start engine, if the word "Power" is not appear, the transmission looks like on 4th gear and the car cann't run at 1st gear.

So i try several times open the switch until the word "Power" is appear, then the transmission will operate normally without any problems on road with different speeds.

 

does this is problem in Computer unit or the gearbox?

 

Thanks

this sounds like it is in ''limp mode''.

the trans defaults to 3rd gear to you can limp home.

 

when you turn the key to run (not to start yet)

the power light should come on with all the other dash lights as a test.

once you start the engine,

the power light should go off.

if it blinks 16 times and then goes off,

that means you had an electrical problem in tghe trans the last time you drove the car.

 

this sounds like a wiring problem,

or maybe a TCU, trans computer, problem.

 

on left hand drive cars in the usa,

the trans computer is located under the dash,(right side i think)

held in by two bolts,

and is a little smaller then a paperback book.

Let me list the problem again in detial

 

I have Subaru Imperza WRX Model 1995

I replaced gearbox with another (for 1997 model)

first week, it works normally, put i noticed "Power" indicator when i start the engine delays a few seconds.

Next week, "Power" did not appear, so the car drive as 3rd gear, after few seconds "power" gets On and flashing, so the car drive normally.

So, i try open switch several times (may be 10 times) until get "Power" indicator ON, and then start the engine.

After Power gets On, flashing  16 times.

What i can do to fix problem?

Is the gearbox fault?

Or is there electrical problem or electronic problem?

I need help

 

Thanks

Probably a grounding issue, or pinched wire.

The flashing 16 times means it has one or more codes stored.You'd have to find the procedure for that trans to get it to flash out the codes or read the codes out of it then see what they mean.

 

Since it was working OK at first after the replacement and then started acting up later maybe check all electrical connections? Maybe something wasn't quite plugged in all the way and became unseated?

Hi,

Read THIS to get the codes stored in the transmission.

 

Did you used the transmission fluid pan to jack it up? If it's dented you may have broke a solenoid or a wired.....did that one early on in my Subie career.

Check your connections, the main connecters to the transmission can be a bear to get clicked in all the way. You may think you got it tight but it may have loosened up as you drove it

Problem was in connections

 

Thank you all
