7AT Issue

ItsErnie · 11-29-2015, 06:27 PM

Im having a weird thing going on with my car. I have a 2014 7AT. On cold starts I always warm my car up to about 3 dots on the little gauge. And when reving through 3rd gear smoothly the car kind of stutters and the revs drop like 200rpm then it just keeps driving normally. This happens everyday, cold or hot weather, and always happens in 3rd gear between 2-3rpms. After a while of driving it goed aeay slowly. Im thinking about taking it to the stealership next week. You guys have any idea what it might be. Thank you.

Can you reproduce it by accelerating hard?

Wot I havent tried, but accelerating harder than normal cruising, yes. It just happens further up the rpms.

It happens accelerating hard as well. Happens in D mode and in semi-auto.

This kinda sounds like the subframe bushing is bad.
SPL diff bushings

Look for oil around the middle-rear of the car on the subframe. The above link is for reference to what I'm talking about.

Is it the engine or rear shuddering? If it's the engine... then the above isn't the fix.

Since your car is 2014, why not take it to dealer for warranty transmission replacement?

I didn't even consider the warranty aspect.... Andy hit it on the head, let Nissan take care of that for you.

The rear doesnt seem to shudder, its more of an upfront feeling.
