7AT - First Gear Lag

ElVee

To me, a valid complaint is how the 7AT doesn't have much grace time in downshifts. In other words, if I'm in 4th and slowing down and I click down to 3rd, it may happen just as the car clicks down to 3rd and then my click makes it go down to 2nd. That's quite annoying. You kinda try to get used to it, but every now and then it surprises me.

I appreciate the responses guys, but never did I state that I was downshifting into 1st gear every time.

I also never said I was ONLY using engine braking as means of stopping. I meant that I use it in addition to the brakes to help the car slow down at a reasonable and fluent rate.

This happens to me when on the freeway. In "D" and wanting to get around someone going slower. I downshift but it goes from 7 to 5 or 7 to 4 -

Also, back to the original question, I think I am now more cautions since lowering the car and when pulling to my work the curb is at a huge slant. Of course I take it at an angle, but all I am asking is why the car seems to lag & rev but not move when I try and accelerate back up the slope

I went back and read the original post again, just to make sure I hadn't missed something important. OP appears to say that when the car is in first gear (automatic trans), the car will rev, lag, rev and then drop into gear and go forward. Did I miss anything?

Unknowns: mileage on the car, transmission fluid level, fluid and filter condition (recently serviced), does the OP get an audible 'clunk' or noise when it goes into gear. Does the problem occur in D or only in 1st.

Thoughts: If fluid is okay (appropriate level and not burnt), then there is an issue with the trans. While there would be a small amount of difference (lag) from pressing the accelerator to the car going forward, the symptoms the OP describes do not appear to be normal. Before an accurate diagnosis can be made, the OP should have someone ride along with a scanner attached to see what the trans is doing. With that information and answering the questions about fluid level and condition, we might be able to better help. Just my

Well that really escalated in a hurry. Yes, @NickTurnon I have had the same lag issues with my 7AT. It seems to spike out of no where sometimes in the lower gears as well. Really hard to tell when its going to happen

maro

same issue here too ,, lags way too much at high temp especially

NickTurnon

Glad I am not the only one..

Why are the three people having this issue with 7AT's in Phoenix? LOL

Sean, how are your fluid levels.

Also, thanks Ghost... I appreciate your reply.
Unknowns: mileage on the car (81k) , transmission fluid level (??), fluid and filter condition (recently serviced) (Yes, Serviced 500 miles ago), does the OP get an audible 'clunk' or noise when it goes into gear. Yes, Sometimes it lags and then revs so much that the tires spin out from under me while trying to go forward haha.) Does the problem occur in D or only in 1st. (I want to say it happens in both, but maybe I am more aware of it in sport mode because I use that often to get over speed bumps and other high inclined exits. But maybe the others can chime in..

My fluid levels are fine and my mileage is only at 23k. I've seen more issues in the early morning when the trans is cold than hot. At the same time I've put 6k on the car in the last year I've had it so it rarely gets hot. There is a pretty solid clunk sometimes when the car is in manual and the car downshifts itself into first, but I'm sure its a diff mount or something like that.

you put it in manual mode to go over speed bumps? you're doing it wrong. anything in a parking lot should be in D

THIS or anything in general that isnt "spirited" driving, i dont see a reason to buy an auto only to shift it manually all the time

Holy **** guys, he's not downshifting into first in a manner that's going to even rev. the engine. Get passed that already.

And it's perfectly okay to not leave it in auto when going through parking lots. Just because you do it doesn't mean it's the "correct way", unless you can put up some stats or documents proving it.


Well, maybe there isn't a manual option for the vehicle?

Maybe the person (in general) cannot drive manual (doesn't know how or otherwise)?

Maybe the person doesn't want a manual?

Plenty of reasons...

Parking lots? Amazon requires no braking or downshifting.
