Lot M 0059: 2014 Chevrolet Corvette Stingray 3LT

Great question! Just to clarify first - the 2014 Corvette Stingray we were looking at has the 6-speed automatic transmission, but the 7-speed manual (Tremec TR-6070) was definitely available as an option for the 2014 C7 Corvette.

Here are the most common problems reported with the 2014 Corvette Stingray’s 7-speed manual transmission:

Most Common Issues:

1. Shift Quality Inconsistency - Many owners report that shifting feel is inconsistent - sometimes smooth as butter, other times notchy or clunky. This seems to be the #1 complaint.

2. Reverse Lockout Problems - The reverse lockout solenoid can fail, preventing the transmission from going into reverse. Owners report the gear indicator blanking out, rev matching stopping, and check engine lights coming on.

3. Hard Shifting into 1st Gear and Reverse - This is actually covered by GM Service Bulletin #19-NA-217, which mentions this can be caused by excessive crankshaft endplay from a damaged thrust bearing.

4. Gear Grinding - Some owners experience grinding when shifting, particularly from 7th to 6th gear if not done carefully due to the close gear ratios.

5. Clutch Chatter - Covered in the same service bulletin, clutch chatter on takeoff is another reported issue.

The Good News: Many owners report that these issues often improve significantly with proper break-in and as the transmission wears in. Some have found that switching to different transmission fluid helps with the notchy shifting.
