<div class="bbWrapper">I seem to get some slipping just before shifting gears. I believe its more noticeable on 3rd or 4th gear. The RPMs move up about 2 lines on the tach and you can feel the slip. It does shift in smooth after but just doesnt seem right and will probably cause wear.<br /> <br /> I have read some threads on this and some say normal and some say its an issue. Anyone experience this?<br /> <br /> Edited: to add the truck has 2800 miles on it<br /> <br /> thanks</div>

<div class="bbWrapper">There&#039;s a shift &quot;flare&quot; because the TC is unlocking between shifts then locking again. <br /> <br /> I think what you&#039;re experiencing isn&#039;t a slip before shift, but rather an unlocked shift up, then TC lockup. If you&#039;re watching the gear display, it lags.</div>

<div class="bbWrapper">Thank You for the valid info. I found this in the manual which explains what I noticed.<br /> <br /> <br /> <h3 class="bbHeading"><a class="u-anchorTarget" name="-torque-converter-clutch"></a>TORQUE CONVERTER CLUTCH&#8203;<a class="hoverLink" href="#-torque-converter-clutch" title="Permanent link"></a></h3>A feature designed to improve fuel economy has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automatically at calibrated speeds. This may result in a slightly different feeling or response during normal operation in the upper gears. When the vehicle speed drops or during some accelerations, the clutch automatically disengages.</div>

There may be some torque management contributing to that as well. I know on the Aisin the torque management (reduction) is significant during shifts to protect the trans.</div>
 
<div class="bbWrapper">This thread just made my day - I&#039;ve been feeling the same thing, and wondering if it&#039;s normal.<br /> <br /> I love what I learn on this forum. Thank y&#039;all.</div>
 
<div class="bbWrapper">I just got my 2021 2500 and with the same mileage is feeling the same thing with the transmission so I assume it the same thing?</div>
