struggling
 

Pacyfica I have a 2007 4.0L. Shakes the whole car for 4 and 5 speed at 1500-2000 rpm. No one knows what it is. Please help.Sorry for my English. Polish talk

Could you be a little more specific, and what does "4 and 5 bigu" mean?

Shakes the whole car and goes calmly into 4 speed between 20-30 mph at 1500-2000 rpm. Sometimes the same course at 5. On the other speed not feel.

I'm gonna guess( without a little more information ), torque converter. My speculation was based on the year of your Pac and the associated TSB on the very issue with the TC. Maybe you could give us some more info, don't edit it, just type what is going on and how often.

Always when it goes for 4 speed. Is above 50,000 miles. Replaced spark plugs, engine mouth because it dealer I recommended. Replaced oil in the transmission, it did not help. 2007 Chlysler Pacyfica 4.0L 6 speed.

Transmission is shuddering

I agree with Pacifica3.82007, the torque convertor has been a common problem with the '07 6 speed transmissions.

the problem is with the torque converter? How much does it cost?

We also have a 2007 Pac touring with the 4.0 and 6 speed. We experienced much the same problem as yours. Chrysler replaced the tourque converter under the service bulletin (TSB) the fractory put out. This should be a free fix, regardless of warrantee. If your dealership bulks at fixing it, take the issue to the district office.

Does anyone have the TSB number?
