Gearbox skipping

[premroy]

On cold starts, the gearbox skips on the first gear.. 

 

Also, when coming to a stop, the 1st gear kicks back in extremely hard..

 

Anyone experience this prob?

 

I'm on the 5spd on a C180k..

happens all the time.. do u drive alot on manual shifts?

[premroy]

Nope, i drive hard, but not on manual shifts. Sent to cycle and carriage and they replaced the valve body, but charged me for transmission oil and filter even though was on warranty for $600++ and assured that my car was fine n safe. I emailed them the same day to tell them that the vibration on the gear knob still persist. No reply. 

 

After which i went to kl on CNY and got stuck there as the gear was stuck on gear 3. Towed the vehicle back to jb and slowly drive back. Now send back to c&c, yet to conclude what they're gonna do.

update us.. feel for u bro.

 

how much was the tow?

[rumboy]

@premroy, wah bro yours jialat, really sorry about it man. CnC should not charge if its under warranty, they should be replacing it for you for free unless you did something to damage it. Just insist it should be replaced bro.

how olds your ride anyway?

Sorry to hijack the post as I encountered rather similar but a bit different. Mine initial gear from 1 to 2 (or 2 to 3) driving off from stop, jerks! When shifting up only, and this happens only the first shift! Same symtoms as yours?

sometimes i encounter this when the engine is cold.. waiting for 60k servicing and see how it goes after changing transmission oil

Try a throttle reset.. Fixes all these small issues most of the time. Its common in our kmpressor models

Just tell the workshop "throttle reset" and they will know? Else can recommend the workshop you have done this and what's the $ damage?

Bro you could do it yourself, here's the how to, try to do it in a quiet place and be patient cause the click can be quiet soft at times:

 

 

Key positions:

Position 0: when the key is just inserted into the slot without any turning.

Position 1: turn the key one click to the right (clockwise).

Position 2: turn the key another click to the right (clockwise). This should be the last position before you crank the engine. To confirm that u are in this position, all your dash board warning signs will be displayed like a christmas tree decoration:becky:

Position 3: Crank position if u turn the key one more click to the right (clockwise) but note that this position will automatically return to Position 2 once you release the presure on the key.

Rest ECU/TCU steps:

1) Make sure your car is stationary with the engine switched off and key out of the ignition and in your hand

2) sit in the driver seat

3) insert the key into position 0

4) turn the key 2 clicks clockwise to position 2

5) step on the accelerator pedal fully to the floor (until you activate the kickdown button at the end of the pedal travel) and hold for > 5 seconds. Don't need to be exact but I usually wait for about 10 seconds just to be safe..:becky:

6) now with your right foot still fully depressing the accelerator pedal, turn your key counter-clockwise to position 0 and hold for >1 second. I usually hold for 3-5 seconds with detriment to the effort.

7) now release your right foot from the accelerator. Your key should still be in the ignition hole at position 0.

8) Wait for about 4-6 minutes (the timing have been reported to varies across different models)

9) in the mean time do not touch anything electrical/buttons in the car as the ECU/TCU sort of "reboot".

10) when time is nearly up, listen for a single "tack"-sound coming somewhere from the steering column. That is indication that your reset is successful

11) now take out your key from the ignition hole and you are done.

12) if you want to drive off immediately, still must complete step (11) before re-inserting the key to start your car as usual.

Bro

 

1) Does this work for all models, i.e. E class, CLS, etc?

2) Does this work if you have a piggyback?

 

Appreciate your advice!
