So i raced a Stock CLS55 last night.(transmission on sport, dampers on sport2 and in gear 1) I caught the jump. 1st gear was smooth, shift to 2nd was good. 2nd gear also went smooth, however when car shifted from 2nd to 3rd it felt less agressive. CLS55 would gain big everythime i shifted from 2nd to 3rd. it wasnt a bog feeling, it was more of like a granny shift feeling. Any ideas??

Also i I did the tranny reset about 3 hours prior to race because car was feeling sluggish during shifts. Car no longer feels sluggish, just granny shifts to 3rd.

It is probally adapting still if you just did it.

I have smiliar issue but when shifting from 3rd to 4th, it takes time to shift like the car keep in same power for a while and then shifts so hard like something may came out the drive train.

I wish if anyone can give us any idea.

Transmission service was done recently, so it is not filter, or oil, or anything related to tranny service because I have had this issue before the service and still there.

how long does adaptation take? i did 5-6 runs in total with the same outcome.

ahmad, how does your car differ since the tranny service?

I have had this problem of delay and hard shifting since I did my mods "first with KLEEMAN header" but at that time it was not so hard like after installing the "TB82 + HE + IC pump".

Even when I serviced my tranny, nothing changed

My car is the same after service, I guess I was not running hard on my car most of the time.

The reset was messed u up without a doubt. I did the same thing b4 I raced Mthis last winter, I reset my ecu like 2-3 hours b4 i raced him and my shifts were PATHETIC. Check out the link. The last 2 races were done about an hour or so later where my car began to shift back to normal but the first 2-3 runs i would just fall behind badly

Car could be getting hot, I noticed the same thing happening at the track. Temps cooled down about 10 degrees when i was on my way home and the lag in the shift was gone. Do a little test, drive the car at a constant 60 mph jam the throttle see what happens, then do the same from a dead start and see if there's a difference.

thanks guys... i hate not driving the car during the week...

I still would like to know why there is a lagging in shifting when I accelerate hard on the car?

It takes long time to shift, yeah, it reaches close to 7000 rpm and does not want to shift then it shifts after some time, this delay in shift is really noticeable and it gets me lose a lot of time.

D S M, all modes has been tried, even without setting the gear to 1 and leaving it as it is on D or S.

Now, I can notice it from 1st to 2nd, don't know what's the reason !!!

Anyway help ??!!!

Suggestion??!!!

Bump!!!!

I too noticed this while recently at the dragstrip this past weekend. Each pass was the same, 1st to 2nd would be fine and then a noticeable lag going from 2nd to 3rd. Feels like a lurch. Almost like the car is revving past redline and finally catches 3rd gear a quarter second later. I had someone else drive my car and he too felt the same thing. I was meaning to ask Jeremy (who was at the event) if he had any thoughts as to what may have been going on. I'm going to take my car to my independent shop to have them take a look.

Thoughts anyone??

ok guys , last week i change it my body throttle ,engine mouths and gas pedal (warranty lol) honestly i got my car 45000miles on it and now 78miles ,after changing this things i feel its brand new trust me change body throttle first you will understand what i am talking about

TopEndS62

did u replace it with a stock throttle body?

Zod

its in the tune we all got it, its just most of the guys in the US dont have the car in full power from 3rd to 4th to feel it...speed limits

it has something to do with torq load limits i believe

Infiniti

this may sound wierd but i just changed my SC bearing and the car is shifting like a beast.

TopEndS62

I could see that making sense.

e551986

yes,mabye it sound funny , but i got back all power

ahmad0658

Mine is solved, tune problem

I have another problem and I hope it is the not the SC , I can hear that IC pump is not running since I have Meziere that is loud, but when switch off the car and start again, the meziere works and power own until I hit the accelerator more than half then the problem is on again

The car lose boost and drive like a diesel car

I will take it to be inspected by STAR today

Zod

who did the tune?

Roseylv

+1

What was done to Solve your issue?

ahmad0658

Jeremy from OE Tuning

saam55

I had the same but after jerry retune the ECU 2 weeks ago , this problem is gone

ahmad0658

My car run great now

No SC problem

Ali_E55

it used to be a tune problem.

but mine now shifts faster than before and it rocks.

i replaced SC bearings this week with roll bearings ( double bar ) instead of the single ball bearings ( stock ones) and it sure is smooth.

roll bearings was recomnded by alot of my friends as they never had a problem, not like the ball ones that comes as stock. they also withstand high rotations.

PS the X6M got in the drag 11.8x. lol it is about 670hp now.

next week im trying with E55 now that i got some Nitto Nt05 on it.

ahmad0658

Ali,

Where do I get these bearings in Abu Dhabi? Part number please.

pearlpower

You replaced the actual blower bearings or s/c cluth bearing. Part# please
thanks
