2009 Ridgeline RTL (with nav) in Bali Blue Pearl
All I can say is that the torque converter locks-up at various speeds and gears. When and under what specific loads it locks-up/unlocks are unknown to me. Hence my recommendation to reduce speed up those steep hills to see if the torque converter produces less heat under those conditions (I think it will).Agreed. Does the G2's TC not lock up in lower gears? The G1's 5-speed will lock the TC in 4th, or even 3rd gear when towing up a long grade. It seems to do it more aggressively either when the ATF reaches a certain temp, or maybe if the PCM determines that you're towing in hilly terrain. IDK which.
