Vehicle has approximately 103,000 km on it,
Issue started about 6-12 months ago, but has progressively gotten worse.
Under medium acceleration there is a hard shift from gears 2-3. Note: May be in other lower gears as well, but most noticeable here.
Dealership has performed a scan and no codes are stored in the PCM and no flash updates are available.
Dealership has cleared the VLP and quick learn and this has not corrected the issue.
A transmission service has not been performed to date.
The next recommendation from the dealership is to have a transmission pan drop service completed.
While I agree that this service should be completed as part of normal maintenance, I don't believe that this will fix the problem.
Are there any suggestions on what might be causing this problem and what course of action should be taken next to correct it?
Thanks
