Problem With The Gearbox

[fahod7]

Hi

I got skyline 99 GT2.5 Tiptronic

it spent 160k

problem is that while driving for 100 kmp/h, the gearbox should be on 4th.

But some time it got to 3th !!!

And the A\T Yalow light turn on

I still can drive but the transmission will be on 3th

What i always do when this happen is that i just stop beside the road and turn off the car for 5 sec then switch on then it work fine !!

Any idea what is going on?

3rd*

Are these 4 or 5 speed autos? I think they are 5?

Does it ever go into 5th if so?

[fahod7]

not sure, i think the 5th not noticeable. But the thing is when i restart the car, it worked.

I took it to do scan and says code : 1D Shift s/v A

do not know what does that mean.

That would likely be the shift solenoid (valve) A .

Time to go to a specialist.

(4 speed auto by the way)

so would shift solenoid (valve) A do this problem ? and how to test it. I just want to make sure.

You test it by believing what the diagnostic told you and following the advice given to you to go visit an auto trans workshop.

As above

How do you plan on fixing it if you don't know what it is?

Typically when they stuff up it is an intermittent problem. So very hard to diagnose , except for the fact the computer is nice enough to yell you its problem.

How about you ring an auto specialist and discuss with them.

I did went to different workshops and both of them could not find the problem. i paid 1$140 for nothing

they just gave me the code and they said we will replace the shift v for $300 with no grantee. ($300) for new solenoid only.

in this case what im suppose to say ?

I got a second gearbox for $300 and i think im gona buy it instead of fixing mine

i have writing this threat to ask if anyone had this problem and what did you do to solve this.

Auto gearboxes are full of fairy dust and witches brew. Normal people do not work on them.

AUTO TRANSMISSION SPECIALISTS WORK ON THEM.

If you did not go to a proper automatic transmission workshop, then we suggest that you do so.

Thanx guys for your commons.

Most of the workshops told me that they will need to open and drop the gearbox oil and test the sensors.

I will do that then will post

Many thanks
