• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

p1811 or p01811 on 03 grand prix se 144,000mi 4t65e transmission

Why'd you replace the trans cooler? Unless it was failing/leaking, or you decided to start towing things around, there's no gain, and only $ loss when replacing them. Not that I wouldn't do it if it was something to keep my engine looking prettier lol.
 


Nevermind the last post. Just did my shift kit today (solenoids and pressure switch this weekend) and because of your thread I picked up a new cooler... didn't put it in yet 'cause I was feeling lazy, but I got one lol. Shift kit installation was a breeze, and ~$100 worth of Lucas AT fluid later, the p1811 is bandaided up and shifting smooth and quick like the good ol' days.
