2005 modus automatic having gearbox trouble, not mine but that of a friend who is having difficulty getting a quote for repairs, even having been to 3 seperate garages,

it comes down to being a new gearbox or selector or both. just an idea of likely cost to see whether it is worth doing or not. is sufficient.

it has just had new discs and pads and quite a bit spent during last 12 months, but it seems to be never without something needing to be done.

any advice appreciated.

Hello Simon,

what problems is your friend having exactly with his Modus Automatic gearbox? Is it dropping into 3rd gear with a jolt, are any warning lights coming on?

Cheers.

Harry.

ye, that's right. jumps out with a jolt, 'spanner' light comes on and message 'gearbox problem'

2 garages have said that there is no adjustment left on selector shaft.

1 garage said that it needs either a gearbox or selector or both.

sometimes it is difficult to go into 'D' from stationary, and takes 2 or 3 attempts to engage.

Hello Simon,

the fault to me sounds like it could be either the EVM solonoid or pressure regulation sensor, both of which are common failures on the 4 speed DPO automatic gearbox which is fitted to your Modus. Even though your Modus is out of warranty, you could give RCS a call as they may well contribute towards the repair cost. Failing that your best bet will be to take your Modus to an automatic transmission specialist. Some are members of F.A.T.E. For more info visit www.fedauto.co.uk. Whats your location by the way?

Cheers.

Harry.

Money on the EMV valve sensor failing, Renault fit a brand new sensor and flash the ECU firmware to tell it to ignore the fault code and not to jump the gearbox in to limp mode (3rd Gear) the improved sensor thing is a bit of a myth, they just fit a new one.
The first computer geek to work out how to flash the firmware on these french Autos to ignore the sensor voltage drop will be a millionaire within the week.
If you stop and re-start the engine 99.9% of the time it is fine until next time , Citeroen's Renaults, Peugeot they all do it, non of them ever cured it.
I bet that firmware disk is kept in a safe at all times under armed guard , it nets them £750 a crack for solving what they should be doing for free, sorting out a badly designed car with faulty software that they sold you.
The garages who want to re-condition or fit a new selector ( buy one from a scrap yard and hope it works) clueless, its a data firmware fault.
I did here a tale of an auto electrician who made a small wiring harness with a switching relay attached that cured the voltage drop in the sensor by maintaining 12 v on the output and drove for years with no problems.
