Bulletin No.: PI1276C Date: Dec-2015 Subject: Difficult to Shift into Gear, Intermittent Gear Pop Out and/or Mushy Shifts (No Grind) Models: 2014-2015 Chevrolet Corvette Equipped with 7 Speed Manual Transmission (RPO MEL, MEP, MEK) Attention: This PI also applies to any of the above models that may be Export vehicles. This PI has been revised to add step 5 in the Recommendation/Instructions. Please discard PI1276B. Condition/Concern Some customers may comment that the transmission is difficult to shift into gear, intermittent gear pop out occurs, or that the shifter has a mushiness to the shift and lacks crispness in shifts. Recommendation/Instructions The shifter assembly neutral position will need to be re-aligned following the procedure below: 1. Remove the front floor lower console. Refer to Front Floor Lower Console Replacement in SI. 2. Remove the upper closeout boot (2) from the transmission control assembly. 1 3. Remove the transmission control lower closeout boot retaining nuts (1). 4. Remove the transmission lower closeout boot (2) assembly. Note: There may be some variation on how and where the rubber band is placed. The above picture shows one possible location. 5. Before performing the shifter adjustment, make sure that the rubber band used to retain the shifter link during assembly is removed. 2 6. Place the shifter into NEUTRAL. 7. Press down to engage the shift control neutral lock pin (1). 8. Loosen and remove the transmission shift rod clamp bolt (2). 9. Loosen and remove the shift control mounting bolts (1). 10. Re-align the shifter and secure by doing the following: Important: The sequence of steps are critical to shift quality. 10.1. Place the bolt in the clamp (2). Important: The bolt must be inserted into the non-threaded hole first, so that it passes freely through to the opposite hole which is threaded. 10.2. Thread the bolt (2) by hand 2-3 turns. 10.3. Place the bolts in shifter attachment slots (1) and thread 2-3 turns. 3 10.4. Inspect for proper alignment in the Neutral position. When the shift rod clamp is properly positioned the bolt will engage the slot/relief in the shift rod and be positioned approximately 15 mm from the shifter assembly as shown above (1). 10.5. Fix if incorrectly aligned by grabbing the linkage and push/pull to the proper gate. 10.6. Tighten the shift control mounting bolts (1) to 30 Y (22 lb ft). 10.7. Tighten the transmission shift rod clamp bolt (2) to 30 Y (22 lb ft). Caution: Refer to fastener cautions in SI. 4 11. Lift to release the shift control neutral lock pin (1). 12. Install the lower transmission control closeout boot (2). Important: Check that the closeout boot fully seats to the shift control lever seal and the base of the shift control assembly. 13. Install the shift control closeout boot retaining nuts. Tighten: Tighten the nuts to 6 Y (53 lb in). 14. Install the upper closeout boot to the transmission control assembly. Important: Ensure the upper closeout boot ID slides below the shifter stub can. 15. Install the front floor lower console. Refer to Front Floor Lower Console Replacement in SI. 16. Perform the Gear Position Sensor Learn procedure. Refer to Gear Position Sensor Learn in SI.
