Under what exact conditions does it jerk. Hard acceleration or normal? When did you have the transmission flushed last? Front and rear diff?

[spydaman617]

like it happens so random i asked my other friends who also own infiniti's and they said the same happens to them. i was thinking it was a transmission issue the way it felt

It could be a shift between 4th and 5th. But there isnt much information to go on as the type of jerk and conditions and such.

[svard75]

Is the jerk between gear changes or does it feel like it's jerking under the same gear while you are cruising at the same speed on a flat road? We're not going to be very helpful without more information.

[spydaman617]

yes its a jerk between 4th and 5th it mainly happens if the roads are wet or on black ice

there is a TSB out for harsh shifting between I believe 3-4th that I brought mine in for.

they ended up replacing lots more bits and pieces here and there, but when I got it back I don't get jerked around anymore..

[spydaman617]

how much did it cost you and what did they do to help

[atm0sphere]

nothing as I had just bought the car and looked up harsh shifting. I don't recall if they swapped out the transfer case for that particular issue, but my first 4 months the car was in the shop for about 10 days for MANY different issues.
