Yeah turning off lockup is bad advice cuz I have been there done that and know I need lockup. My damn tranny right now runs so damn hot without a lockup. Also I think non lockup with an A3 doesn't quite have this heat problem cuz you're running the engine and tranny at a 1:1 ratio. In OD, trans is turning faster than the engine and creates a lot more heat. Is that right? That makes sense in my head anyway.

My sentiments exactly.Why drive a powerful sports car if you want 4cyl gas mileage you cant have everything.I had a grand national with a 200r4 and it was non lockup didnt cause me any problems like posted earlier th350 and 400s dont have lock up and heat will kill any tranny not just 4l60e

I have my OD lock-up set at 45-46mph and it doesn't unlock until 41mph, I need to raise it because I always have to tap the brakes to shut it off under 45mph where it shutters.

All of these symptoms just point to the tune and not
the converter. Turning it off is just giving up. If you
want it to jump up when you give it gas, fix the lock
and shift points. If you want it not to buck, get your
fuel and spark right (or unlock before you get to the
place that's mis-tuned). If your lockup is noisy then
fix the apply pressure / PWM. It takes some time to
school it (which a session tune may not want to
spend) but there's nothing difficult about it, just a
lot of personalized preference tweaking.

Keeping it unlocked put's undue stress on the tranny.No reason to while cruising down the highway.With alittle work on the tune you can easilly get it to lock/unlock smoothly and quickly. My car has no lockup in 3rd and in 4th it locks at 58mph due to the Cam thats in there.

I have D locking at 27mph and OD locking at 37. So nice to be able to so quickly forget that I have a converter at times. When I first saw this thread, I hoped you were referring to lockup under w.o.t. So far, mine locks at 105 under w.o.t., but we plan to test it both ways. My $.02
