I found this very good post in an earlier thread.
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 - (01/26/2004)
DTC P0757 Set, SES Lamp Illuminated, Poor Performance of Transmission, Transmission Slipping (Clean Transmission Valve Body and Case Oil Passages of Debris)
1999-2004 Passenger Cars and Light Duty Trucks
2003-2004 HUMMER H2
with 4L60-E/4L65-E Automatic Transmission (RPOs M30/M32)
This bulletin is being revised to add model years and change Cause and Correction information. Please discard Corporate Bulletin Number 01-07-30-038A (Section 07 - Transmission/Transaxle).
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 (367). 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 (368) or 2-3 shuttle valve (369) were stuck, restricted and/or hung-up in its bore.
Correction
* Inspect / Clean the 2-3 shift valve (368), the 2-3 shuttle valve (369) and the valve bore of debris / metal chips.
* Inspect / Clean the 2-3 shift solenoid (367) opening of debris / metal chips. While inspecting the 2-3 shift solenoid (367), 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.
