Torque converter unlocking when it shouldn't
This is not really a tune issue because I had things dialed in perfectly until I sent the TA to the shop to rebuild the engine. The engine was not removed from the car and the transmission shouldn't have even been touched.
Whats happening - and I've seen a view threads here with the same symptoms, TC locks perfectly at the right speeds/throttle position. The problem is when the load is reduced it will unlock. I'm running a SDOS for what it's worth.
Why would / could this just suddenly happen?
