| Problem withgearbox Error code P0741 |
|
My name is Willy, I live in France and I am the proud owner of a discovery 3 of 2006.
I bought recently (6 months) a discovery of 230000 kilometers (gearbox had never been drained)
From the beginning, I had problems of idle speed variation in steady speed.
I made a first drain.
The problems faded slightly, but were still present.
I changed the torque converter.
The D3 has been metamorphosed in terms of driving and consumption. I thought my problems were solved.
5000 kilometers later, I had a jerk in the transmission at the approach of a stop. I had the "default transmission" information on the dashboard (and the P0741 fault code with my IIDtool).
I stopped the car. When I restarted it, there was no problem.
Since, I realized that sometimes the transmission does not work optimally (in this case, if I put my shifter on sport or in commandshift mode, there is nothing indicated on the board of edge - neither the term "sport", nor the gear on which I am).
At each start of the car, there is never a problem. However, I never know when the defect will reappear.
Since then, code P0741 has been displayed only 3 or 4 times. I had about twenty times the display of the transmission fault.
I think the ideal would be to change the solenoid TCC, but I would like to have your advice before I start the operation.
Do you know where I can buy a solenoid (and possibly other parts to change)?
Do you have a modus operandi to change this piece to provide me?
In advance, thank you for your answer
PS:I think you'll understand, I do not speak English very well ...

The code relates to TC slipping. Was the TC replaced with a new one or secondhand one. When you changed the oil, did you replace with lifeguard 6 and new filter. Other possibility is the Mechatronic problem

The TC is a secondhand.
When I do the replacement, Iput a new filter and lifeguard 6.
To my mind, it can't be a mechanical problem. Yesterday, I drive the D3 for 140 Kms and neither had a problem!
For me, I think It's electrical.... but where? I don(t know exactly....

I changed all of my solenoids to rid the p0741 and p0734 p0733 codes. LR Discovery 3

The issue of no sport mode or command shift is likely to be corrosion or a faulty shifter PCB, i had this recently and replacing the shifter with the matching short wiring loom fixed it.
I left my sunroof open during a summer storm and it took 6 months til the issue appeared.
