Scotty, I've owned five cars since I started driving in 2006, a 1991 Mercury Topaz LS, 1997 Oldsmobile Cutlass Supreme, 2008 Chevy Impala LS, 2017 Toyota Corolla, and now a 2019 Nissan Maxima SV. Since the 2008 Chevy Impala I notice cruising around 40mph the transmissions seem to "lag" when going back to the gas, even the Corolla. What causes this?
Can you please try to better explain what you mean? Maybe make a YouTube video & post the link here?
Mainly it's computer software they want to get the best gas mileage possible so the computers have a shifting leg they're not as tight as the old ones which used a lot more gas but had a lot more response
Alright thanks, I never noticed it in the Mercury or the Olds but the rest definitely had it. I thought I might have been doing something wrong. Also thanks for the Nissan advice as well. Once my equity levels I'm getting rid of thos puppy lol.
As Scotty said, a lot more computers and more focus on MPG. Part of the "it learns your driving habits" bit of technology that transmissions have nowadays.
Thanks for your response, I remember reading some information about cvt transmissions doing that but wasnt sure it was a reliable source. My dad was a mechanic for 25yrs and he said the same thing you did the other day lol.
What we drive nowadays is rolling computers. So much is controlled by software to eek out the best mpg's. The other thing with modern cars is that there's no longer a physical throttle linkage from the gas pedal which gave instant response. There's basically a variable resistor that sends electrical signal to the throttle body. (Drive by wire). In some vehicles there's also a noticeable throttle response lag. Again, those dang computers and sensors etc.... From personal experience it's more noticeable in automatic transmission vehicles. One reason I keep driving manual transmissions. It's ever so slightly still there but negligible.
It's called gear backlash and it's an inherent property of autos. There's just a lot of moving parts inside.
Don't gears have to some play in them for them to be able to work? Same for watches, etc. I think.
there are different kinds of "play". The backlash kind is undesirable.
