Need help regarding 7th gear slipping
Has anyone had a problem with their manual transmission slipping out of seventh gear? Only 2500 miles and have had it in for service to repair. Dealer put a new shifter boot on the shifter. No help. The problem occurs at highway speeds usually on down grades. Very frustrating having to constantly reshift into 7th or drive in 6th and accept less than optimum performance. Would like to know if this is unique to my car. Taking it back in 10/28 for service. Any comments from members would be helpful.

Never had a bit of problem with it slipping out of ANY gear (VIN 11822, Z51, 15K miles). My first thought is misaligned linkage but it could be deeper in the tranny.
By the way, I'm trying hard not to laugh at your dealer over the shift boot thing

Haven't seen any posts like that here. In other forums, it could be some worn internal parts, but yours is new. A shift boot is causing it to kick out of gear--that's an odd solution.

Same here, no problem in any gear. May be in the trans where the detents are controlled.

On my old transmissions in my older cars and Vettes, the rubber boot can put enough pressure on the shift lever to kick it out of gear.
I've never heard of it being a problem on newer cars though.

My apologies regarding your vehicle's transmission slipping, especially since it's back at the dealer for another diagnosis. Although I understand your displeasure, it's great that you've proactively reached out to your dealer again about this situation. Keep us in the loop and updated on your service visit. If necessary, I can contact the dealer's Customer Experience Managers if you have additional questions. We'll look forward to your updates

I think it's something like this. Kinda like the classic Porsche 996 Turbo 2nd gear pop out issue. Exact same symptoms. Of course in that case once it starts popping out it's too late for simple fixes.
