Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hello. Welcome to Just Answer. Please allow me to assist you. In our shop, we have observed this issue many, many times. There are two different possibilities for the service department to do.
1.) Reprogram the computer (this works about 15% of the time, but they have to do it first).
2.) Replace the clutch pack inside the transmission
We have had reprogrammed computers last for several months before the issue returned. Other car, the shudder was back the next day.
Your recommendation would be to have the new software programmed, and drive it. If the shudder returns, request that the replace the clutch pack assembly.
Fortunately, both of these rectifications are covered under the warranty program.
You are very welcome. The seals, if faulty, should be replaced. I would ask for the upgraded seals, but, as a rule, manufacturers do not replace parts that are 'good', even though there is a better part available. Since you are looking at the vehicle being out of your hands for a bit, they owe you the courtesy of doing any upgrade that is available.
