Well at first I had a stock 4l60e and it was doing the same thing code p0757 . So I tought well shift solenoid is bad or tranny is fucked. So I replace the tranny and put in a built stage 2. It was origannaly built by century back in 05 and the guy who I bought it from re built it. Well put it in and drove good for about 1 day and bam code came back. Before 3rd and 4th will stay hung and not shift. Well when I replace the stock one oil was burnt to hell so I was like well clutches were screwed. So the built one after 1 day same thing but this time its only 4th 1st 2nd 3rd work perfectly fine. So my theorys r 1. The car has some kind of splice wire somewhere in the harness?? 2. The car was tuned for 3.73s and now has stock gears, could the tune be messing with the shift points and causing that too happen with the 3200 stall and yes it was tuned with the stall. 3. I just need a new shift solenoid 4. I'm curse cause every car I get always brakes lol ... help!!!

You do need the pcm programed for gears and with that stall po757 should also be turned off in tuning as its a common false code caused but a high stall converter

So that code is what is causing the trans to get hung and not shift into forth cause of the huge stall?? So if I have someone with HP tunners have them go in and completely delet that code. It should shift perfect and not be happening no more? And also get it tuned for stock gears??
