Hard down shift, but we did the 30k service and drove with tech all wired and no indication of transmission issue. We will monitor as there may be an issue with some of the shifting in the transmissions
Transmission began slipping. I exited highway and transmission failed completely, leaving car unable to move under its own power. Replaced the failed transmission with a rebuilt unit.
Three days after I had gotten the car back after the completely failed transmission had been replaced by a GM-supplied factory rebuilt transmission, the car started having intemittent transmission slippage. My ODB II scanner showed a code related to something called an "internal mode switch." The repair shop which had installed the transmission had gone out of business on the very day I picked the car up, but my former service advisor there sent me to the local Buick dealer, Pearson Buick-GMC in Sunnyvale, CA. Dealer service personnel replaced the valve body plate and the internal mode switch.
Car was experiencing a periodic slight shudder, similar to driving over rumble strips but less severe. Would also experience periodic jerks along with the shudder. Problem was in torque converter. Replaced w/re-man under warranty.
Leaking seal between transmission and transfer case. Seal was re-used in prior reported repair. Dealer replaced seal at no charge.
Transmission would not go into 4th - 6th gears and reverse. Replaced seals in the trans. and new gaskets and fluid.
Transmission was slipping at slow speeds.

They told me it was a bad wave plate. Still under warranty
same problem as last month. The wave plate replacement did not fix the problem. Multiple times since, I have not been able to get the car to move. Took to dealer, first they said it was the battery, then said they couldn't find anything. after getting no satisfaction in terms of successful repair, having the vehicle not move when put in reverse or drive, and having dealer tell me nothing was wrong with the car, I traded it in.
Car is still currently in the shop. Torque tube has been replaced and determined not to be the issue causing driveline noise. They are currently replacing the rear differential.
Transmission over heat.
Rebuild the transmission
Trans start top shift erratically then progressively got worse and worse until it was more or less undriveable. i do not remember exactly, but i think a clutch plate broke.
Apparent failure of Pressure sensor in the Transmission Control Module (P0752). CEL and transmission went into limp mode, second and reverse only. GM has issued a service bulletin for this failure mode.
Another transmission rebuild. Repairing dlr stated that the dlr who did last repair (10k iles ago) didn't do it correctly

Car would not drive above 20 mph, took in to dealer and they fixed after a week with no charge. Transmission replaced December 2013 under extended warranty.
worn cv joints
Transmission blew on a back road in Oklahoma with only 60000 miles on car. It is the result of a known issue with the 2008 Enclave--a defective wave plate. Transmission so damaged, it could not be rebuilt.
Noticeable slipping shifting into 3rd and slightly into 5th. Lurching when in reverse. Replace 3-5-Rev housing,sun gear,control solenoid assembly, replace all necessary pistons, seals and gaskets

Transmission reflash and front tire well replacement.
Leak in transmission cooler line. Replaced under warranty
Complete failure of transmission. Had vehicle towed to a GM dealer who did a complete rebuild. Extended warranty has expired so my cost was $3600.00 (discounted). That was a hard pill to swallow seeing the low mileage.
Transmission leak detected by independent shop during routine oil change. Install new transmission seal(s).
gears don't shift properly, won't go beyond first gear.

Would have kept it but had incident of engine feeling like running on 5 cylinders. Checked it out and determined I might have the 2008 tranny problems.
Reflash of transmission shift points.
TSB update that I found (not the dealer, in fact, they couldn't find it at all until I gave them the TSB#). Transmission has poor shifting, flash update but there will be another one, mark my words.
Both left & right axle shaft seals were leaking.
Transaxle seal(s) leaking at transfer case. Repaired under the 100,000 drivetrain warranty.
Transmission failure. Another victim of GM's famous transmission "wave plate" problem. No reverse and would not shift out of low gear. I believe that this is a known problem to GM but they are yet to step up.
engine and transmission reflash
The check engine light came on and the vehicle started making a revving noise when in motion. The transmission control module needed to be replaced.
Transmission fluid leak has been ongoing but very slow. I had to allow the leak to build in order for the technician to find it. Replaced passenger side output shaft seal under warranty. No more leaks. I paid to flush transmission.
OIL LEAK FROM TRANSMISSION/TRANSFER/TRANSAXLE. DYE WAS ADDED AND MANY SEALS WERE REPLACED DURING THE REPAIR
Transmission after driving highway speed for 20 min or more would fail to shift past 4th gear, even in manual mode. Check engine light came on and DIC indicated overheating fluid. Shop has determined that entire trans must be replaced.

Wave Plate Issue, which has since been issued under a recall notice.
transmission searches for 3rd gear before finding it.
I took the Enclave in for transmission flash which helped, but did not cure the early shifting. There will be no more flashes for the '08 so will have to live with it, or sell it.

shifter paddle failed.
Transmission would not shift, wave plate failed.
Car did not shift out of 1st gear at times. It looks like they repaired it under the special policy 14404A it says on the work order they removed and replaced the reverse clutch plate. It seemed like it was a fairly major transmission rebuild.

It was moist, not quite leaking so I had it replaced since I already had the vehicle in the shop
