A4 throwing code, advice please it is throwing P0757 which is: P0757 Shift Solenoid B Stuck On
I just recently installed a converter, my car doesn't seem to have a problem shifting should I be worried about this? I read that I should just delete the code, what do you guys think anybody with the same issue?
I found this info on a google search but doesn't help make my decision
Cause
The most likely cause is chips or debris plugging the bleed orifice of the 2-3 shift valve. This will cause the transmission to stay in 2nd gear and return to 1st gear when and/or if the PCM attempts a 3-4 shift. DTC P0757 code may also be set if the 2-3 shift valve were stuck or hung-up in its bore. Inspect the 2-3 shift valve and the 2-3 shuttle valve for free movement or damage and clean the valves, the bore and the valve body passages.
Correction
The 1-2 and 2-3 shift solenoid valves (also called A and B solenoids) are identical devices that control the movement of the 1-2 and 2-3 shift valves (the 3-4 shift valve is not directly controlled by a shift solenoid).
The solenoids are normally-open (not energized electrically) exhaust valves that work in combination to shift the transmission into four different forward gears. Opening and closing the exhaust valves within the solenoids redirect the transmission fluid, hydraulically moving shift valves and the corresponding shifting of the transmission gears.

Do a search on this site for that code, you'll get tons of hits. I got that same code a few days after installing the converter in my car...edited it out..no more problems. Get the code edited, and you'll be fine.

We have the same TC/gears - didn't have any codes after my install. I'd clear the code and triple check the trans fluid just to be sure, mine was low after driving it around for a while.
