Hi Guys just wondering if any of the RRS Forum members in South Wales have had a Gearbox Mega flush carried out, if so where and when and would you recommend having it done. Having some gear change issues and occasional Fault " limited gears available " has happened on one occasion.


Cheers

If you have a genuine, mechanical gearbox fault, a flush is likely to finish off the gearbox...

Your best bet would be to have it plugged into a diagnostic machine, and see what fault codes are stored.

A blocked fuel filter, failing fuel pump, sticky brake switch or dodgy brake light bulb can all cause the same issues though, so we'll worth investigating

As DM says get it checked out first

but

can say a gearbox flush is a worthwhile maintenance item, just had ours done and thought it was smooth before hand, now even better, can tell on the down change when going up a hill how smooth it is.

Should be good for another 100k now.

Hi Guys thanks for your replies, just had timing belts and engine oil change done ( picked her up at 5pm tonight) and on test drive they noticed she was not changing gear as she should be. They checked for fault codes but nothing showing up. This was at a local independant land rover specialist.

Brake bulbs and brake pedal switch would be first port of call

Cheap enough to be replaced as a service item

Low fluid level also has a similar effect.

Bristol transmissions is probably closest for gearbox problems if it is anything more serious.  Bodsys Brake Bible

RRS booked in for mega flush next week, checked the oil and it is almost black. Will have a look at the brake light switch as well. Both Brake light bulbs replaced recently.
Will report back next week.

hi just picked up on your thread on 20 th match i live in swanse and looking for a mega flush, how did you get on ,did it make a differance and if you dont mind what was the cost many thanks danny

Hi Hamner the Mega flush/ gearbox service that i had done did make a difference to the gear change, but i have had the Fault 'limited gears available' since the oil change. The Gearbox service was more than just a flush as they also changed the Oil pan and filter and was not cheap at £450. If you just want a flush and you are not getting the Gearbox fault as i have been having, then yes i would go for the Mega flush. The gear change improvement was noticeable from pulling away from the Garage.
I had my gearbox service carried out at DATSC in Barry who are ZF transmission specialists.

Hope this of use to you Danny.

Cheers
Mike

thanks for your reply , i will give the guys at barry a call cheers hamner

Hi Danny here is their number 01446 327007 and 08000337092.
Be specific as to what work you want them to do.

Be prepared for a wait as it took at least 4.5 hours to do the gearbox service. I had too wait for the work to be done so went for a walk over to Barry island etc. But if someone can pick u up you can always go into Cardiff for a few hours. Not much in Barry to do.

All the best
Mike

Here is their website address as I forgot to put in the message above.

hi mike ,cheers for the help i like the look of your rrs nice colour and wheels ,did you get the niggles sorted in the end . mines a tdv6 in silver hse 2005 i havent worked out how to up load any pictures yet , thanks again danny

Hi Danny I have now fitted a new brake light switch to try and sort out my gearbox fault, need to get fault codes checked and erased and maybe re
Flash the gearbox ecu. Have not had time to take the rrs on a decent run out since brake switch was changed. I work shifts and had the weekend off but went out on the pop instead. Last weekend of local rugby and then 3 games to watch on Sunday afternoon.

Like I said be specific in what work you ask them to do for you. Gearbox service was £450 worth of work, the oil sump/filter was about a hundred pounds plus the oil which adds up to the cost as above.

Cheers
Mike

Before you spend any money on a "gear box fault", have a read of this sticky -->
http://www.rrsport.co.uk/forum/topic35871.html

Basically, if you some times notice the box won't up-shift, try it in sport mode (command shift), and check that it will manually up-shift, if that works, check that you have the same make of tyre across each axle, as the difference in rolling radius of different tyres makes the gearbox think it's turning, so it won't automatically up-shift.
