Correct me if I am wrong, but I know that the ecu learns the drivers style of driving (whether its aggressive or grand motherly) and learns to shift the car.

I was wondering if anyone knows the speeds at which automatic transmissions are supposed to shift... I know in the manual it shows the recommended shifting speeds for manual transmissions, but does anyone know the normal speeds at which the ecu shifts for a 2008 g35x with an auto tranny?

I ask because while getting on the expressway (it was on a slight incline), i was giving it gas (did not floor it) and it didnt shift up. It stayed in the same gear while accelerating all the way to 60.... The car is not slipping, and it is accelerating, but it seems like it only shifts if I floor the car.... in which case the rpm revs upto 6000 to 7000 instantly and the car flies.

I usually drive the car like a bitch (gas is expensive in ny lol) and rarely go past 4000 rpms so I thought maybe the ecu learned my style..... but wanted to make sure my tranny wasn't malfunctioning. Thanks for any feedback guys

 

reset ecu to see if you notice a difference?

 

Really? How is that possible. Normally it will drop a gear or 2 depending on how far you push the pedal. that's if i am in 5th already. But if that didn't do that to you just reset the ECU and everything will be back to normal when you 1st got the car

 

it could just be because of the incline, AT's tend to stay in a lower gear on inclines to reduce stress on the engine and to have enough torque, depends on the conditions and road on many occasions

 

U guys think I should reset just the ecu or should I do the other resets as well? Throttle, idle air, etc..

 

Just the ECU!!! it will only take 5 min to do
