Does manual mode impose long term durability lost by using them? i really like to use it but if it decreases the durability then might as well put it on drive all the time. I apologize if there was already a question like this before, but just making sure, 2015 gs 350 f sport

 

No. Feel free to use it but it has limited benefits.

 

I like the paddles better than the manual shift, especially when in a turn ramp. Its just easier and you can keep 2 hands on the wheel.

 

I use them mainly for quick downshifts getting on on-ramps to the highway. In Atlanta, if you don’t enter the highway at 80+mph...you can die haha

 

Your ears will tell you if the transmission isn't happy. I used them all the time in lieu of braking.

 

There is a difference between using paddles in "D" and "M". I know this for a fact on 6 speed AWD models, not sure about 8-speeds.

Using paddles in M for downshifting give smoother downshift with better rev-matching.

 

Definitely a difference with the 8 speed too.

 

I use the left paddle to slow down when I see cops.

 

I prefer to use paddles in manually when traffic is slowed down to a crawl. You can limit the number of shifts made, which should in theory result in longer life.
If the traffic is moving along very slowly, you can keep it in 1st gear manually (or 2nd if speed is high enough).

 

Does reducing shifts really prolong life? I would assume that would mainly apply to a transmission with a clutch to reduce clutch wear vs an automatic?

 

If less things are moving then it should definitely extend the life.

I do the same thing in ****ty traffic - leave it in manual and just stay in 1st gear. Less shifting and less braking

 

Yeah I definitely see the reasoning behind that but then the car has to rev way higher in 1st gear putting more stress on the engine.

 

I'm not sure this makes sense. The shifts are synchronized and happen automatically. There is no gear grinding or riding the clutch here so I'm not sure how you're "saving" the transmission by not using certain gears. It's like someone not using auto folding mirrors in fear of wearing out the motors that power the mirrors. These things are designed to work under a number of conditions and for thousands of miles.

 

yeha as this is a torque converter auto so im assuming its not doing wear or tear by shifting, what im concerned about sometimes though does it wear a lot more when we put it in manual mode instead of just leaving it in drive lol, which you guys made some awesome points.
