Should I just replace the fluid and filter?

Where is the solenoid located?

 

Sounds like you need to put some shift solenoids in to correct your problem.

 

Where are they located?

Do I have to pull the Tranny?

Do you carry the solneniods?

 

1. They are located on the rear of the valve body closest to the trans mount.
2. No just the trans pan.
3. Yes I have brand new borg warner solenoids in stock. I can also send you a new gasket and filter.

 

Have you recently put in a converter? If so, did you have any tuning done afterwards? If so, what tuning?

A lot of people will have that code after they install a converter. Nothing is wrong with the solenoid, the computer just needs tuning to handle the converter (or further tuning).

 

I am having the same problem now also.Replaced all the valve's in the valve body,the wiring harness and flushed it 2 times.I think it may have to do with the stall converter,but i have had it in there for 6 months and it just started.Gonna just delete the code if i can't figure it out.Sometimes get a p0300 too.

 

Yeah, I have a PI 3200 stall, been in the car about a year now and has been tuned.

Here's some interesting info:

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.

I had my stall put in recently and got PO757 and PO751. My tuner turned off the codes and the car still ran like ****. I changed my trans fluid and replaced the 1-2 shift silenoid and the problem was solved.
