last week i was driving the truck and all of a sudden the engine light comes on. i then noticed the truck seemed to be slipping in first gear. i got the engine code read today and it was P0757 "2-3 shift solenoid valve performance". i assume my trans wasn't actually slipping, but rather stuck in 2nd gear. well now the truck is fine and i have all 4 gears. i've driven it a few times since the code popped up and everything is normal. should i be worried or just clear the code and move on with life? thanks in advance.

 

did you just install your converter?

 

^^^ what he said

 

Yeah i just recently had this SS3600 installed. truck ran fine for 2 weeks though before this problem popped up.

 

disable the code, its nothing.

Mine did it also.

 

yeah i just did a search for the code on here (should have done that first) and looks like it's a common problem with high stalling converters. i'll have my tuner clear and take out the test for it.

 

yup I get that code almost every time I drive as of late. I just clear it using my Aeroforce scan gauge. I need to just disable it.

 

Yes you do haha

My truck would stay in 2nd or 3rd gear from a stop. The first time it happend I was like, WOW this thing feels loose as hell right now, wtf.

 

Yes its a common code with high stalls I have ask more than once why tuners don't just automatically remove the test for it

 

Yup mine throws it in 3rd gear too. If it happens I just clear it real fast. As a matter of fact I'm going to disable it tomorrow.
