First gear is too heavy

[tenno]

I am experiencing first gear too heavy to move my car. But there's no problem with other gear position. Mine is using auto. It is occur when start to move the car from static position and accelerate after decelerate to low low speed. Is that cause by gear problem or not enough power to drive at first gear? Seek advice from community. Thanks.

The lowest gear i.e. "1" have the highest torque to pull your car from stationary.

BTW, did your engine RPM goes up during 1st gear but the car not moving.

Bro, are you sure that's the 1st gear????? i think that is the 2nd gear

one way to find out, push to sports mode 1st gear when you accelerate.:top:

You r right Elixir. I think it must be 2nd or 3rd gear. Jarance, my car start to move at 2000RPM. What actually the cause yeah? Most probably gear prob right? Any idea what wil be the consequent? and solution? I have read that front wheel drive gearbox oil are not recommended for rear wheel drive. Any violant effect if we r using front wheel drive gearbox oil for our UDM?

When you release the brake does you car moved from the stationary spot?

Please use the correct transmission fluid for the GB. Do NOT use other cheaper ATF. you will regret it later if you do.

Nop. Car still stationary even brake is released. I've notice that is gearbox problem since the indicator appears on panel. FYI im using Castrol TQM st recommended by mechanic who did most UDM before and the price much more expensive thanTQD III..its around RM130/4liter. And now i notice that oil does not meet the requirement. Aiyaa..experience foreman pun susah mau percaya sekarang.

Should i overhoul the gearbox or just rectify or changed the gearbox straight away?

If your car remain stationary when you are in "D" and brake is release, then you do have a problem.

Possible cause:-
1. GB Low ATF level.
2. GB Choke Filter.
3. Main Aux Pump for ATF is faulty.
4. Solenoid is faulty.
5. Clutch plate is worn out.
6. Wrong ATF used?

Get it check ASAP by workshop who have a diagnostic tool.

I have the same problem of copper seal broke at the aux pump and all the ATF leak out. Car cannot moved when in "D" and brake release. Car manage dto move when rev higher. Was told we should NOT drive the car when there is no ATF coz will wear off the cluth plate.

When the mech open the sump, there is no oil left. Luckily for me, the ATF was flushing out all the metal part and no filling got into the GB. Chaneg the pump for about 1K plus 400+ for the oil. Total cost part + labour - about 2K. Add 980 for torque converter as the sleeve was also worn out. Did not overhaul the GB which will cost about RM5500 to RM6800.

Haha Jarance. Maggie also expensive now. Lates mech had check with his computer showed that "gearbox monitoring faulty". Gearbox faulty indicator also not appear on meter panel. He said something might be wrong with the computer system. Advised to go after wireman. Then if no joy have to do what you did before la. Thanks alot giving more idea.

Usually, the alarm is registered in the memory when the alarm is detected. When the fault is clear, the instrument cluster will not indicated. The alarm memory is kept for diagnostic purpose. The fault have to be cleared by the tool. If it come on again, then the alarm will be registered.

I dont think seeing a wireman will help you to solve your problem.

If you car cannot move when you are in "D" mode and brake is release, you do have a problem with the GB..

Jarance, where did your oil go? No leak? Simply disapear? so I should open the sum as well as you to know whether theres an oil inside or not. Any recommendation on ATF to be used for my 318 1.9 Japan full spec Y2K?

I simply dont like maggie..

I think I did mention that the copper seal for the hydraulic pump was damaged due to misalignment. The misalignment was caused by a damaged GB mounting.

I was doing an aggressive overtaking and the seal cracked. All the ATF was shooting out from the GB thru the crack seal near the Aux. Pump. I also notice white smoke was coming back from my car. At first, I thought it was due to the wrong petrol that cause the loss of power but found out later that the ATF was splashing on the exhaust pipe causing the white smoke.

Cant remember what the oil but I think it was a white bottle sold at about 1 litre bottle.

 

[adriangzh]

jarance, ur white bottle isit ZF- LIFEGUARDFLUID5? 1 litter per bottle

i did try to flushing gearbox oil. But sad to say there no shop around can do coz they need special adaptor to connect the ATF flush machine to GB host. Nothing suit. Btw i had the oppurtunity to see the ATF that so dirt. And that dirt has block the ATF to flow nicely to GB coz when i opened up the other hose, theres only small amount get through. I presumed that sum is empty as yours. Probably plate also worn out but pump still working. Now surrender at workshop. Hopefully not get conned. huhu.

Btw i have a Q, is that realy white bottle ZF as you mention only suit for tiptronic GB only? (this was said by mech). I think as long as it is Dextron III(manual say), is good enough.

It have been discussed many time about the correct fluid for the GB box. Many people think that all ATF are the same but unfortunately it is not.

eg.. Some of the longlife engine that is used by authorised dealer is not available in the shop. It is specially formulated for BMW to run the 25,000 km. but create sludge problem on some car who follow the same schedule of oil changing.

Where did you did your GB flushing? Did you also change the filter in the GB. How much did you use to top up the GB. Did you use the recommended oil like ZF?

Yes.. I think you should know cos you are the GB specialist..

Since you are here.. Could you explain what are the problem faced by most E46 owner with the GB?

I have my GB aux pump fail at 100,000 KM for my e46 but not for my E36. My E36 GB fail @ around 150,000 KM which required complete overhaul.

There is also alot of discussion of the ATF to use for GB. it there any difference?

I did not flush the GB since most of service workshops dont have hose connector/adaptor to connect the ATF flusher machine. though there have multi choice adaptor but nothing suit. I had look after many workshop including one regularly servicing BMWs. I cant bear to drag my car here and there which will cause more harm to GB. I did change the ATF last DEC where the milage now around 15K. Cant remember how many litres used. 6 litre i thought. Im using TQM st since mech said that ZF is only for tiptronic or stiptronic GB only. At same time the other UDM was filled up with ZF-reason was that car is tiptronic.

Need to know more wheater it is true?
