Under Full Load Won't Change Sometimes

[Steven87]

Hi the other day I've noticed when I was turning onto the freeway I gave it full throttle, it wheel spin then as it was going instead off it changing into the next gear it felt like I lost all throttle and it felt like when u wheel spin with traction control on and didn't want to change into the next gear until I backed of and gave gas again, the traction control was turned off. But then after I tried it again and as it was about to change in to the next gear it paused abit then went into the next gear.

The auto was full flushed 5000kms ago and I've had it tuned not long ago

Just abit worried as I dnt want to blow it up

Anyone else had similar problems.

Thanks

Just got bak from driving it. When u hold foot to the floor it hits abit over 6k rpm so I'm guessing it limiter n I gotta back of. Also I found in sports mode it sometimes doesn't do it. But it looks to me it only dose it going to 2nd and maybe 3rd gear

Been modded? my bf f6 has been modded etc and I get the same thing..... best to just use tiptronic for when you put your foot up it

Found out it dose it when you get a tune done so only way to fix it is getting the zf tune.
