diagnostic help needed

Hello All,

I need your help!!

I took my RRS 2.7TDV6 to the garage today because I thought that the auto transmission was starting to fail. The garage took it for a run, and when out the engine lost all power, and went in to failsafe mode.

They turned the engine off, and back on, and it has worked fine.

I have not yet read the error codes (the garage is actually a gearbox specialist, so they don't have the diagnostic tools), but they are probably going to bring it round tomorrow and I will plug it in to the IID tool, and see what the errors are, but here are the symptoms...

not always, but when at approx. 90KPH (5th or 6th gear, engine around 1500rpm) I get a vibration like I am driving over a corrugated road. It is VERY slight, but I can definitely feel it.
All gear changes are fine. Fuel consumption is fine. Gearbox oil changed 1 month ago (filter and oil not flush).

Mechanic is not convinced that it is a problem with the transmission, and thinks that it could be an engine problem.

Does anyone have any ideas?

I will post the error codes as soon as I can get them, but at the moment I don't know if it has stored any.

Any guesses?

The driving over a corrugated road is a regular description of a failing torque converter in fact I felt it myself on my own sport last year.
The power loss is a separate fault which could have any number of corses wait until you have the codes read. 2008 G4 RRSport TDV8 current
2009 TDCi 90 current
2016 Discovery Sport HSE current
1994 Dakar current

So you need to get the codes read as posting this on here and Disco 3 you will only get the same response until we have the codes we cant really say if it is a transmission fault or an electronic fault that is causing your car to cut out but from what you have said and has already been said it does sound like you TC needs a new one Thumbs Up

OK... the mechanic came round, and I plugged in the IID.

The error was the MAF.

The error has cleared, and it is running perfectly again.

The chap is obviously honest... he advised me not to have the gearbox refurbished because he said that there is nothing wrong with the gear-changes etc.

For the vibration, we are going to replace the torque converter (as many people say this is the problem). The rest of the box seems to be fine, and all gear-changes are perfectly smooth.

It should be finished later this week, and we will then see.

So... my next question... where should I get the new MAF? Original LR? OEM? what is the common consensus on here? For the D2 TD5, the MAF had to be Original LR as the others caused many problems.
