I don't have codes either. Since solenoids replacement a year ago, haven't seen a transmission code again. 90 or 95% of the time shifts well, but sometimes shifts hard.

My car is 56k miles.

Did you change the various megatronic sleeves & bump stop while you were in there ?

Yes, solenoids and all mechatronic sleeves. I'll update when check the fluid and/or reset values.

I replaced the mechatronics seal adapter in the transmission 3 weeks ago and have not experienced this issue since. Don't confuse this with the "sleeve", the mechatronics seal adapter is located at the top of the valve body and sits between it and the body of the transmission. You will need to drop the pan/filter and remove the mechatronics to get to it. It is a very simple task...just do your tranny service with this along with the sealing sleeve as well. The mechatronics adapter is about $10 and the sealing sleeve is about $17 (it is known to leak).

Here is a great website for transmission parts:
http://www.thectsc.com/

Here are the links for the parts for this fix:

Follow this task to replace the adapter:

UPDATE!!

After a few months of driving I have found the "bump" came back! So, just replacing the parts I listed above did NOT fix the problem. I did finally get it fixed though. I ended up replacing all of the solenoids in the mechatronics which has fixed the problem permanently. Here is a link to the kit:

http://www.thectsc.com/index.php?p=p...d=36&parent=52

Right now it is on sale for $455 dollars. The kit comes with instructions...it is really simple. Once you have the mechatronics removed, you separate the plastic piece from the body and the release a retaining plate. The solenoids then just pop in and out easily. Make sure you get the correct kit for your transmission, the link above is for the 6H19/26/32 M-Shift. You may have to pull your mechatronics out first to visually verify which model you have.

PM me if you have any questions.
There's my problem ... explained well.
