P0757 Okay, I am not stupid and pretty much understand what this means, the problem is that I am not really noticing any problems. Namely I do have all my gears working and other than over heating the TC going up some mountain passes, resulting in the TC getting looser (went back to normal after cooling down), I havn't noticed any ill effects on the Tranny.
Should I look for any particular signs of trouble with this SES?
I am pretty much going to baby the 4L60E from now until I get back to the US to get it built.
So with that said what I am asking is the following:
1) What signs of trouble usually follow the P0757 SES?
2) How much does it cost to have the existing 4L60E built (including labor)?
Thanks guys.
Lets see if the local OPEL dealer will warrant the tranny when I bring it in.

Okay, Now I think I might not really have a problem. Can anyone confirm that it could just be the converter confusing the PCM resulting in this code or could it be this:

DTC P0757 Set, SES Lamp Illuminated, Poor Performance of Transmission, Transmission Slipping (Clean Transmission Valve Body and Case Oil Passages of Debris) #01-07-30-038B - (Jan 26, 2004)
DTC P0757 Set, SES Lamp Illuminated, Poor Performance of Transmission, Transmission Slipping (Clean Transmission Valve Body and Case Oil Passages of Debris)
with 4L60-E/4L65-E Automatic Transmission (RPOs M30/M32)
Condition
Some customers may comment on any of the following conditions:
The SES lamp is illuminated.
No 3rd and 4th gear.
The transmission does not shift correctly.
The transmission feels like it shifts to Neutral or a loss of drive occurs.
The vehicle free wheels above 48 km/h (30 mph). High RPM needed to overcome the free wheeling.
Cause
The most likely cause is chips or debris plugging the bleed orifice of the 2-3 shift solenoid. This will cause the transmission to stay in 2nd gear when 3rd gear is commanded and return to 1st gear when 4th gear is commanded.
DTC P0757 may also be set if the 2-3 shift valve or 2-3 shuttle valve were stuck, restricted and/or hung-up in its bore.
Correction
Inspect / Clean the 2-3 shift valve, the 2-3 shuttle valve and the valve bore of debris / metal chips.
Inspect / Clean the 2-3 shift solenoid opening of debris / metal chips. While inspecting the 2-3 shift solenoid, look for a screen over the solenoid opening. If the solenoid DOES NOT have a screen, replace the solenoid with P/N 10478131 that does have a screen over the solenoid opening.
Refer to the appropriate Service Manual for additional diagnostic information and service procedures.

Ok guys, now my car does this too, same exact symptoms. The dealer tech thinks its the 3-4 (might be 2-3 cant remember which)clutch pack. He needs to open the trans up and see.
I'm debating just having them install the solenoid to see what that does ($274).What do you guys think?
Thanks Chris
