High Transmission temps

Slick!! Were you not locked up when you down shifted to 2nd?



Something I noticed, is when you are in lockup, say in third, with OD off, when you switch OD "on" it shifts to forth and stays in lockup. I was at light acceleration and it felt like a shift with no unlock. I wasn't sure if it briefly unlocked, because it felt pretty solid. I have done this several times by accident and was not under heavy acceleration. Don't like the idea of shifting while pulling in lockup.



I am wondering if the controls are doing a quick unlock to keep the stresses down but locking up quickly so as to give maximum power to the wheels. If so it would be handy for maintaining momentum.

No, the torque converter isn't locked when I shift to 2nd gear. It quickly locks when I accelerate past the ~20 MPH mark. Since I don't tow, I only use this feature when hauling my slide-in camper driving up steep mountain roads with sharp switchbacks that require slow travel.



Yes, I noticed the same thing when going to 3rd locked to OD locked. Like you, I don't do it under hard acceleration. I don't want the driveshaft rolling on the ground out from under the truck.

Good, a little more play room.
