Just appeared. 

 

No radical behavior difference (YET), though driving at lower RPM seems to "pulse" a bit more than usual.

 

Codes do not disappear with ECU code re-set (Cobb), but do not cause a SES symbol on the display. 

 

There is a new display error icon on the top right of my display above the heat gauge that I've never seen before; obviously transmission related.  It looks like a partial transmission with 2 "legs," one of which is a broken line, the other one is a solid line to what appears to be the wheels.

 

Again, the code is P0872...Cobb shows it TWICE, but P0873 doesn't appear, or any other code.

 

My look-up of this shows:  TFP SENSOR/SW C CIRC

 

Just now, I went back out after parking the car...the codes are still there but the icon is gone.

 

Any suggestions?

It’s a transmission fluid pressure sensor error. I’d log it to see what the pressures are compared to what they should be.

Thank you.

I have no experience with this, other than I did a couple of logs 2 weeks ago (before the problem yesterday) which I'm posting here.  Can you or anyone with experience "SEE" anything further, moving toward what to do next?

 

Car is a 2012 modified GT-R with Shep 2.5 trans.

Data logs from before the problem started won't really help. Do a new log and send it to John Shepherd ([email protected]om). He will get back with you pretty quick. He is the only one I would want suggestions from.

Thanks.

 

Actually months ago I was E-Mailing back-and-forth to one of his people.  The question at that time was low-speed drivability and any clue as to whether my ETS was failing or not. I used the same parameter set-up for the log that Jack's Transmissions recommends on their video.

 

I'm pretty sure that I was told that they only evaluate Ecutek logs, not Cobb.  That seems strange to me, but what could I say?
