Hi
I notice this last days:in the morning when i select D and leave brakes car wont crawl.
As i press gass it engages then returns back to mormal.
Sometimes i notice it crawls really slow when i leave brakes also.

So i assume this is normal.

is your emergency brake on?

 

[umitbat]

Nope,brake is off.

I have the same problem with my TD6 2003.

On medium cold mornings, I can release the handbrake, put it in D and nothing happens, I can even rev the throttle a bit, and then after a while it will gently start to move forward.

however if I put it in R it creeps backwards as normal, also if I manually select 1st gear it crawls away fine.

on warm, or very cold days it works fine. My mechanic friend has suggested it may need a software update on the gearbox. He suspects the Torque converter is a bit lazy on cold mornings around 0-5Deg. C.

My Son has a USA SPEC 2003 HSE 4.4 Petrol, and his doesn't do it, but there again his RR has a different gearbox.

Anyone else experience this, and have a solution?

Regards
Steve

Do u think that gear is engaged and brake is holding you?
Mine feels like it is not engaged till i step a little gas.

Something i experience last days is in moderate accelarition while upshifts from 4 to 5 it first lowers the revs,hesitates then shifts up.

Gearbox drain, filter change and refill.

Gearbox drain, filter change and refill.

We did it 500miles ago.
The oil was black witout any metals.
But we didnot make a flush.
If i rechange the oil do i have to change the filter again?

I don't get any feeling the brake is holding, or any problems once it is going, just on startup in D on reasonably cold mornings.

I haven't had a gearbox oil change, I considered it but my mechanic friend said it was a wast of money unless I was having change-up, change-down problems, or the slow pickup happened at all times/temperatures.

......however if I put it in R it creeps backwards as normal, also if I manually select 1st gear it crawls away fine.

The only difference between manual 1st & auto 1st is the LRC is engaged to bypass the low sprag to provide engine braking. The LRC is also engaged in Reverse.

It could be that the low sprag is sticking 'off' but that the level of 'stick' is fluid temperature/viscosity related, perhaps?

Mine happens only at first movr,after it becomes normal.
Likely some oil cant get filled at idle.
What about hesitation from 4 to 5.
When i climb ,rev does not settle immediately,stops in mitlle then settles.

This morning it engaged so fine instantky.
Can this be due my manual drive revving up a couple times yesterday?
All in all it is an oil system,smt it works to rush things.
Yesterday i talked to a known automatic expert,who said morning eng. is not an issue.
We checked the oil,when drained it was almost red-most black-changed it 500 miles ago.
I think it must be changed a couple times to get the oil in the system all exchanged.
