Last year I replaced my transmission AND engine (trans went bad, engine had 150K and was tired; got really good deal on both). The new engine trans (from '10) had 50K miles. I had my shop replace the torque converter just for piece of mind.
Now @ 165K
Last month on a road trip it started throwing the dreaded 'P2757' trans code. NOTE the trans NEVER felt like it was slipping or shifted odd. WIth the exception of the code it seemed perfect.
Fearing the trans was shot I bought a '17 1794 but kept my 07 because it has the SC.
On a gamble I got a new SLU solenoid from Ebay for 135$.
About an hour later got the solenoid installed and fluid replaced (got a new storage tub the night before with a snap shut lid. It measured about 18"x40"x6"). Kept everything hospital room clean.
After test drive NO CODES!!!! I couldnt drive more than a few miles at +50mph without it throwing before.
Now I have a supercharged 07 with about 65K on the engine trans AND a new 1794!!!!
If anyone else has the p2757 it is WELL worth replacing the solenoid before replacing the trans.. Truthfully it wasnt much more difficult than doing an oil change.
Needless to say....I am off the f-ing charts happy the trans is OK.
