Honda Jazz Gearbox & Transmission Problems
Which generation Honda Jazz had a transmission issue related to the CVT?
The problem you refer to affected the very first Jazz models sold here up to 2008. Any car made after that date should not exhibit the same problem as Honda made running changes to fix it back in the day.
The problem was actually traced back to the wrong transmission fluid being used in the CVT unit. These modern transmission are very particular about what fluid they use, especially with regard to the complex brew of additives that make up the fluid.
Over time, the fluid in the affected Jazzes would start to break down as the additives became depleted, at which point, it wasn’t doing the complete job necessary. Specifically, the depleted additive package suddenly allowed the starter-motor clutch to remain engaged. Essentially, you had the transmission trying to drive the car and the starter clutch dragging at it, effectively trying to slow it down. Which is when the car would start to shudder.
The solution was to switch to a new, reformulated transmission fluid which was added to the drained CVT, the car driven for a certain distance, the new fluid dumped and refilled and then the ECU reset to recalibrate the transmission. Problem sorted.
Honda Jazz 2007: Transmission problems
There was a lot of trouble with the auto transmission in the Jazz of that era. You don’t say if the transmission that was fitted was new or used; if it were used I would suggest the transmission is the problem. You also mention the fluid being changed, it’s very important that Honda fluid is used, and you say it was when it was changed, but you don’t say what oil was in the transmission before it was changed. The damage might have been done before the fluid was changed. I think you could be up for another transmission.
Are there any problems with the transmission in the Honda Jazz?
The CVT transmission in the Jazz was prone to shuddering. To fix it Honda introduced a service requirement on the transmission, basically to change the oil. The automatic transmission in your Mazda is not a CVT, and does not suffer the same problem. But automatic transmission specialists will always tell you that it's wise to service automatic transmissions to prolong their life. It's even more important if you do a lot of towing.

I would take it to a Honda dealer as the company has been replacing problem transmissions. At the very least have the gearbox oil changed. If you choose to do nothing it's likely to get worse, and you could end up replacing the transmission.
Honda Jazz shaking
It's a problem with the CVT transmission and one that Honda is aware of and has been rectifying. Take it back to your dealer and have them assess it. They might be able to fix it by changing the oil in the gearbox, but in some cases they have replaced gearboxes.

Hopefully you have kept a record of the times the oil has been changed and the result. I would take that to the dealer in the first instance and present a claim to have the gearbox replaced, as has happened with some other Jazz owners. If that doesn't get the result you want, move up the chain, and if necessary go to the consumer affairs people as the last resort.
Another shuddering Honda Jazz
The first thing dealers usually do when they get a shuddering Jazz is to change the transmission fluid, which is a special fluid for the purpose, and that appears to fix most cars. In some cases it doesn't and in those cases it usually means the transmission needs replacing. Trading the car is drastic, but if that eases your mind then so be it.
Shuddering Honda jazz
It would appear that Honda believes your transmission is operating acceptably, but you clearly don't. Maintain the pressure on the dealer and Honda until they fix your car, and keep meticulous records of all dealings you have on the matter. This will back up any claim you might have later on.

No, it should remember your driving style and start off again normally. If it shifts in an odd way then take it to a dealer and have it checked, but it’s most unlikely that you will do any damage to the transmission.
