Iam about to give up on my car.
So I have been having a problem with my 07 fit with 166k on it. Started a few weeks ago I was driving when all of a sudden my car started jerking and bucking. The check engine light then came on and the D light started blinking. Now I had a similar problem before and had all 4 coils packs replaced. This is almost the same feeling so I took it to the shop and my guy said it was the transmission speed sensor and he replaced it. It ran perfect for about two weeks until this morning. I really want to keep it since it is my work car and I don't want to use my new jetta for work since I drive alot! I just don't want to keep putting money into it. Can someone give me their opinions please.

Get an OBDII code reader and find out what codes were thrown when your CEL came on. If you don't have one and don't want to invest, there are a few auto parts stores who will read your codes for free. Here in the US, I've had O'Reillys do this for me. Knowing what codes were thrown is the first step in the diagnostic process.

+1 I bout a Bosche Code scanner for 75 bucks from Oreillys, it works with an iPhone or Android. It shows all the codes, you do have to pay extra on line to activate ABS diags.
Its been invaluable working though all the quirks I inherited for the PO.
I use it in a phone holder while I drive. It let me diag a sticky thermostat, Let me watch the codes to make sure it was happy enough to pass emissions. etc.

Make sure that you use cvt fluid from honda for your cvt tranny.

Jerking and miss on acceleration (under load) is ignition system fault.
jerking when coming to stop that eases out when car begins to roll can be caused by defective torque converter (fails to release) but this VERY rare.

This statement stood out to me:
If they weren't OEM or Hitachi "053" packs (sticker on the top) you COULD be seeing failed coil packs again. (It has happened to others many times, the cheap parts don't work for long)
The Hitachi packs will cost you ~$200 from Rock Auto...

Thanks! I will do this tonight after work

So I took it to AutoZone and this is what I got from the code scanner.
P0717 - problem in the input shafts speed sensor circuit.
P0718 - input shafts speed sensor intermittent failure.
Sounds like what I just had replaced two weeks ago. Any opinions? ?? Thanks !

I'd bring it back to the shop that installed it.
Perhaps the tranny speed sensor has just come loose so that it isn't picking up the pulses from the bits inside the transmission.
otherwise you might have a pinched wire or bad connector.
Here is someone else's fix with pictures

Good luck.

The short (input shaft) sensor and wire connector are located under transmission (canister type) fluid filter on the top of the housing.
HOWEVER, few post on other Honda forums point to countrershaft sensor problem. Its signal is priority to PCM (like its signal is a standard that never goes bad), ask Honda engineers why.
So:SPARK NOTES:
1. Car starts shifting weird while driving
2. Gear selection felt like being rear ended
3. OMG BLINKING D AND CEL
4. Engine trouble code p0717 and p0718
5. Replaced mainshaft speed sensor ("pickup assy")
6. Didn't work brought it to Honda
7. They replaced countershaft speed sensor
8. So far, so good
CONCLUSION: (for future readers and whoever else may be trying to fix this same problem)
Codes P0717 and P0718 are electrical circuit problems AND CANNOT BE CAUSED BY MECHANICAL ISSUES IN THE TRANSMISSION. That is straight from the horses (Honda's) mouth.
There are only three things that can be wrong,
1. The wire harness (cuts, breaks, shorts)
2. The ECU (PCM)
3. The sensor(s) itself

This other sensor located on firewall side of transaxle housing
