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
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.
Leak from transmission seal. Defect from previous warranty work.

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.
Transmission over heat.
Rebuild the transmission
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.
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.
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.
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 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.
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.
Reflashed the software for the transmission
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.
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.
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.
Reflash of transmission shift points.
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.
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.
Transmission started slipping.Refused to go into Reverse a few times.Check engine light came on,after car downshifted into a lower gear by itself after I came off a freeway exit ramp.Service dept reset the check engine light&I TRADED it in!
Rear seal of transmission replaced as it was leaking; wave plate replaced.
The valve body in the transmission had to be replaced. The vehicle was hesitating to go into drive - and then began only going into first gear without changing to second, etc. Limped it to dealership under its own power.
Left front axle/CV joint leaking and making lots of popping sounds when turning. Had both sides replaced.
engine and transmission reflash
I was close to home when my car was slow to respond after being at a stop sign. I had three stop signs to get home and each time, it was very slow to respond. After I got it home, could not put the car into gear at all.
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.
3.5.R Wave plate was cracked and spread metal all through the transmission. Replaced wave plate, piston, clutch steel, housing and seals
Wave plate failure. 3-5-R waveplate.
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.
Wave plate broke -- required new transmission. GM paid for $1,200 and I paid the other $2,500 for a remanufactured tranny with a 3 yr 100k mile warrnaty. This is a known issue in the 2008/2009 Enclaves (and traverse and Acadias).
Reflash transmission controlling computers. We received a tsb on this.
The dreaded clutch wave plate failure. Wave plate and associated parts replaced.
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.
Shift solenoid stuck. replaced solenoid and rebuilt valve body
Transmission reflash to improve shift performance.

Transmission - no reverse, 3rd or 5th gear. Transmission was removed and rebuilt.
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.
Seal in transfer case blew. The seal was replaced, drove car for a week but still leaked. They tried to replace seal again, when it fell into the transfer case. They eventually replaced the entire transfer case having the car for over a week the second time.
transmission oil was too low to detect on dipstick.
