2001 Nissan Xterra. 143000 miles. Automatic.
Car is lurching/bucking/jerking when driving and at idle.
A little history: I had a rebuilt transmission put into my car about a month and a half ago. Since then, it has been into the shop twice for leaking transmission fluid in large amounts. The most recent time some main seal had broken and all of the fluid cam out of the car. Seal was replaced, car declared leak free. That was 3 weeks ago. Less than a week ago I had it looked at to make sure it was road worthy for a trip of 100 miles total. Was told all is well.
Immediately after returning from the roundtrip, the I was driving along just under 40mph when the car jerked/bucked strongly. It almost felt like someone hit me. After that it started jerking as I reduced my speed. I pulled it into a parking lot. Shut it off and then restarted it. Sitting there idling it was doing the same thing and the tachometer was dropping to almost zero before rebounding.
I have already gotten a new noc sensor, new spark plugs and boots, a recent oil change, and then of course the transmission and transmission seal that I previously mentioned.
I should also mention that since getting the rebuilt transmission installed, the car clunks/jerks violently about 50% of the time when I put it into reverse and sometimes jerks as the car slows when coming to a stop.
My concern is that the transmission is failing, perhaps because it has had the fluid come out twice since they put the new trans in?

Are there any loud noises associated with this other than just changes in engine speed.

Yes and no. When I shift into reverse and it clunks you can definitely hear it. Also, the big lurch when I was driving sounded like a clunk but when it was doing it while idling I couldn't hear anything.

It's sounding more like an engine problem to me. You are going to have to get a professional to look at it and determine that. They will probably have to start with scanning for any stored trouble codes.

Okay, if there aren't any codes then what?
What kind of engine problem could it be?
I've only owned the car for 6 months and it's been in the shop 6 times over the last two months. I have an extended warranty that covers the big stuff but I'm really getting frustrated.

You need to get the car diagnosed. I can't tell you from your description.
