Does anybody know how to fix this code?

 

I think that is a shift solenoid code. I am not sure what the fix is, I am sure someone will chime in.

 

I don't know how to fix it, but it has something to do with the tranny shift solenoid.

 

Damn, you beat me to it.

 

Thanks Brian,
Like always, you are on target. It happens "sometimes only" when shifting from drive to reverse. The motor just stall. Truck still on warranty, going to the Dealer tomorrow.

 

Second Thanks for 2000 Silverado. He was quicker because he has a Radix.lol

shift B solenoid just reset code and see if it comes back again, mine did the same thing today and i just reset it and hasn't come back on yet lol The reason it might have stuck is a lack of voltage or a surge in voltage or if you reset the code and it comes back on then its bad.

 

v8,
The problem is not the code, the problem is the engine sometimes just die by switching from drive to reverse. When it happens then it shows the P0757 code. By clearing the code it wont solve the real problem.

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.
