I have a 4l80e and like it says my truck was throwing a P0752 code - 'Shift Solenoid A stuck on'. So I bought the solenoid, dropped the pan, and replaced it. Then, I put it all back together, filled it up, and drove it.... After 15 miles or so it threw the same code again..... Any ideas what could be wrong? Also, I have looked over the wiring. Nothing seems to be broken....The transmission was replaced about 5 months ago with a brand new one (not rebuilt) Thanks for the help.

 

Same code on 2002 WS6 4L60e with 3200 stall. Was told by trans expert its a false code. Its set by TC some do some dont. Needs to be tuned out. Dont know, convertor been in for 3 years.

 

This is a stock truck...2004 2500HD 4x4 6.0L 4l80E. Its shifting from first to second at 2500-3000 rpm. Z QQH 6 said that his WS6 has a stall converter in it and thats why it is setting off the code. Do you think I could possibly have a torque converter going bad? Any ideas are appreciated. Ive checked all wiring and connections and replaced the 1-2 shift solenoid. Still getting a P0752 code....

I dont think its something that needs to be tuned out due to the fact that its a stock truck with all stock parts

 

bump for monday....any ideas?

 

So the truck started shifting around 3000 rpms today.... I think it may be a torque converter going bad? Due to the fact that I've replaced the shift solenoid.... Anyone wanna confirm or shoot down my idea?
