Today, it was a nice sunny day....

So, I went a bit heavy on my CLS, under heavy acceleration and SS shifting 2nd-3rd in the 5,000 -6,000 rpm range and and my CLS was literally jumping forward.

It that something normal?

 

I have a 2001 CL and when i throw it from 2nd to 3rd it does that. I think i has to do with what rpm you are shifting at or maybe the hesitation for the changing gears are forcing a little more gas to be burn and it jumps. I would like to know the real answer also.

 

our engine loves this winter weather !

 

Mine does the same thing too. I wonder if it has to do with the timing retardation during upshift, so that the shifting does not feel rough/abrupt. The outcome of this retardation is a sensation of surging forward between gears?

 

I had some thought that is the first signs of slipping... I hope I would be wrong..

 

i've experienced the same, i hope the transmission isnt slipping...can someone shed some light on this??? ....i'm at 22.5k miles now....hmmmmmmmmm

 

Mine does that too, but I like to think it's just the delay during shift that the tranny is supposed to do. Don't make me sweat.

 

i kinda know what you're talking about... when i shift at high rpms with my car i kinda have to grip my steering wheel tighter than normal, otherwise it feels like it wants to break loose.... sucks

 

No that is the torque steer if the steering wheel is not straight and you are pushing it.... That would more pronouced if the pavement is wet or slippery...

 

I get the same thing too. Its prolly the delay in the tranny shifting. I thinks its kinda cool. Feeling the VTEC and then a quick torque neck snap when shifting. JMO. It can get annoying though.

 

I just got my transmission replaced a month ago and mine does that too. I don't think that this is a sign of transmission slippage...

 

It's just the time between the shift initiating (pulling out the 2nd gear) and completing (putting in of the 3rd gear and continuing acceleration).
If it becomes EXTREMELY pronounced then it is slippage, but a splitsecond lag is nothing to be worried about in an automatic transmission. This is not SMG II.

 

The PCM/PGM-F1 will retard the ignition during the shift to try and cut-down on the amount of shock to the clutch packs (by reducing power); the timing returns to normal after the shift.

Remote diagnosis is hard, if you ever get the dreaded 5th - 2nd 3rd -2nd slip (flare) symptoms, then you better watch out (the revs seem to shoot-up like a fried clutch in a manual box)...

 

Thank you for confirming my thoughts.

 

actually happens all the time w/ headers

 

true My car jsut like literally flies forward and i could just burn rubber much much more It must be the lower temp.
