'08 ISF 2nd gear slip on cold start
hey guys,
did a quick search and did not find anything related to this. my apologies if this is a known problem and has been discussed.
I noticed on cold start , when I start to accelerate (usually i push down maybe 20-30% on the peddle. not WOT) i noticed when the tranny shifts from 1st to 2nd there is a sudden jerk that feels like a slip in the tranny.
you can hear and see the RPM shoot from like 3k to ~4.5k (during the shift) and back down to less than 3k on the 2nd gear.
This only happens when the engine started from a cold start and accelerating at a moderate pace.
After a minute or two , i start moving from a full stop and it doesn't do it anymore.
Anyone else heard of this issue before? is it something I need to pay attention to?
Other than this everything else runs smoothly. just wondering if this is a common ISF problem.
i have a 2008 model. All stock other than a Borla cat-back.
thx!

To everyone else experiencing cold flare on the 1 - 2 shift - this is common.

thanks all for the comments. i feel more confident now that it's not something i have to worry about.
anyone know why it happens though? or if there's something we can do to prevent it?
its a small thing but i just hate that jerk motion it causes when it happens.
or does this happen on the models 09+ ? if not, maybe someone from Lexus may know what improvements they've done in the newer models.

What specifically (in terms of low fluid levels) do you suggest I look for, or tell the dealer to look for? I might just bring it into a few other dealers and have them check it out. I'm still under warranty so I want to get this **** sorted out before it's too late.
