Anyone?

 

Did you screw a $5 oil pressure gauge in test port and verify if you have an actual internal pressure issue. ECM's are easily fooled by an over zealous sensor.

Torque pattern is critical installing a valve body to avoid vb twist and inevitable seepage
The thermal connection you describe seems to point to this probability..
Just a shot in the dark..
tow it to my shop, I will fix it

Now I'd love to do that but I'm quite a ways away. Now where is the test port located?? I know it's been a while but it still does the same thing. It hasn't gone into ep mode but it still is rather clunky. I've had the tranny fluid drained and filled multiple times since then and still clunky.

 

Hey Forteexe,

Did you ever get this resolved? I have the same setup as you do, 06 MCS with the revmax valve body replaced.

I'm having the same codes as you are on a generic scanner. But when I use my more advanced scanner it pops up a more in depth description on the 0700 code instead of just "transmission fault".

0700 Aisin TCU obd relevant fault.

I'm thinking the TCU/TCM (transmission control unit/module) is bad, and that controls the solenoids to shift.

Another thing that's happening with my car is the shift indicator on the plate next to the shift know only lights up N and D, all other positions don't like up. And SD doesn't work when I move the shifter over. However the shifter paddles do allow me to shift gears.

 

I did end up getting it fixed, after calling revmax and replacing three different solenoids it worked fine for about one year, then I started having the same issues again as I did before the replacement, well being out of revmax's warranty I got it replaced thru a shop and haven't had any problems since. The gears have all been recalibrated according to them and it is better than new. Mine only put itself into EP MODE when any error would occur. I never had any other funny problems other than either getting the transmission "stuck" in 3rd or 5th gear while in EP MODE.

 

I'm having the same exact issue. Same code on the OBDII scanner. When run through ISTA+, it gives me an 000700 (DME: AISIN TCU OBD relevant fault) and a 002921 (EGS: Electronic pressure control valve SLC1). I also ran Function/State information using ISTA+ and it gave me mA readings for every Solenoid but SLC1, which had 0.00mA. (all the rest had readings like 990mA, 100mA, 1,000mA, and 200mA). I'm hoping my problem is just a bad SLC1 solenoid. I'm currently stuck in 5th gear as well. I had reset the adaptations with ISTA+ and the trouble all happened on my first time out, in just a couple minutes.

 

Try replacing transmission computer module
