Default '08 Automatic Transmission problem ?

I have a '08 Automatic (Z51).
Around 23,XXX miles ... normal driving mode

Just lately, right when I take off from a dead stop, it shifts hard into 2nd gear.

Always have taken great care (not raced, no burn-outs, no crazy hard driving) of my car.

All the rest of the gears glides thru the auto transmission flawlessly.

No dipstick to check ... but I think it's time to make an appointment at the Dealership

Anyone else have this kinda problem ?

Could be minimal, but it also might be time for a drain and fill. After all, regardless of miles it is an eight year old car (or thereabouts).

Firm shifts are better for an automatic than easy shifts. Less slipping of the clutch packs. But if it just started might need to change fluid and filter.

My tuned A6 shift hard under heavy acceleration and no problems at 153,000 miles. Shifts so hard it will break loose at 70 going into 2nd at full throttle.

Glad this question came up. I also have an 08 non Z51 Auto with 27K that shifts hard into second and has some hesitation between upper shifts from time to time. Car has not been abused. I was wondering if after 7 years the fluid was no longer completely effective. I have also wondered how common this condition may be and hope to read any additional feed-back.

'08 here as well. Always good to try and stay ahead of some of these issues.

OP, please let us know if a fluid/filter change cures your problems. Good luck.

Will do


of course, in true car fashion, I had it out for several hours drive tonight and it didn't do it once ...


I need to take it in for the recall, so I think I'll go ahead and have the tranny service done at the same time


Will keep you updated

I have an 08 auto that had problems with second gear. This occurred at about 45,000 miles. First they tried replacing some seals. That didn't work so they did a complete rebuild. Still doesn't feel correct but is better. Now have 78,000 miles. Dealer said the way it shifts now is normal. Seams to slip some before shifting at times. Most other automatics I have driven were much better than this car.
