7AT - First Gear Lag

NickTurnon · 03-20-2014, 11:27 PM

Hey everyone -

Been dealing with a slight issue lately. Don't know if its normal and I just never noticed it, but when I downshift into a turn and then slowly accelerate to get over a bump or get into the turn, the car lags and revs up but doesn't go anywhere. Then after about a second or two it kicks back into gear and lets the car move again...

Makes me only want to take turns into shopping centers and exits in "D".

Anyone else experience this little lag? Not a serious issue.. but didn't know if there was a reason for it.

Any help is appreciated

What's wrong with downshifting into 1st?

Hmmm... torque converter maybe trying to catch up??

Weirdaadada, but seriously change ur fluid man to Redline w70 or 80 cant remember check ur manual for the weight #.

Also ur solenoids need lube/changing, but that one is tricky cuz if u dont know how to do it dont do it, give it to the pros.

The first thing I'd check is the trans fluid level and condition. If the fluid is good, I'd look into the torque convertor as Wonka2581 mentioned. Since you seem to like spirited/hard driving, changing to a "high-performance" fluid (per DOOMMONKEY777) would be worth looking into.

Change his trans fluid to redline? He's got an auto.

Having the dealer drain and fill the tranny is about all you can do, right?

definitely not for a 7AT the redline D6 shows it is for use with NissanMatic S systems though if you change the fluid on the sealed system and your transmission craps out, good luck getting them to cover it under warranty

Are you serious or kidding? Can't tell sarcasm over text.

It's almost the worst thing you can do to a transmission, even with a double clutch. Just use 2nd.

So first gear is there for what exactly?

To op there's no reason to downshift into grocery store parking lots. What the hell are you even doing?

I have a base model and the brakes are terrible.

When i am going 40mph on a city street and theres someone riding my butt, my brakes will give me wiplash, so i generally engine brake on most of my stopping. Also, who doesnt do that? You're telling me no one else downshifts to help them slow down?

Anyways, fluids were all done around 8k ago. But I will look into trans fluid & torque converter

NickTurnon · 03-21-2014, 10:24 AM

Also, this happens in first or second gear. The car will lag, rev up, lag again, and then click into gear and will go forward.

I am not sure why all of you are getting so angry about the 1st gear thing.
