ER34 RB25DE Auto - Would a flush ever fix an "A/T" light?

[thatjawncrazy]

gentlemen (and others)...

at 157k km on my rB25DE auto sedan and am getting an every-so-often A/T light, with the usual loss of whatever gear i'm in at the time. it always goes away once i restart, but i read the threads and watched every video and am told it will only get worse.

i have zero evidence anyone has ever done a trans flush on this car.

is there a chance that doing a flush will fix the problem, rather than the usual "replace the A/B solenoids"? just curious. rather not flush, seal it up again, then have to drop the pan all over again...

Get a scan tool on the Consult port and see what the TCU has to say for itself.

was my first thought, but a couple hundred for the cable/adapter plus not having a laptop that can run NIstune/NDSI/ECUtalk or any of the usual programs is the issue.

honestly i'm going to flush it anyways and so i guess this is a little like asking people to internet-diagnose my car. 

just wanted to see if anyone's ever had an A/T light go away purely by doing this though

Just go to a quality workshop that has a quality scan tool and ask to plug it in for a few minutes. Throw them a six pack.

Nobody around me has a Consult (USA east coast)  

Either way I ordered all the parts to do a trans flush so guess I'll do it anyways.
