Renault 21 transmission shifting

My Renaults MJ3 transmission has been working well but it wasn't going into second, however three weeks ago the hydraulic distributer needed both it's mounting plate gaskets replaced, the job was done properly and the transmission worked well and changed into all gears beautifully. However after several days I did a long trip that involved going up a hill on a very windy road, the transmission made it through in the end but as it went to change into second after a normal corner near home the engines reves increased dramatically and the transmission stopped pulling up the rise. I immediately stopped and turned the car off and on again and checked the pull, the car got me home but it hasn't gone past first since and won't pull in reverse it just makes a plastic gear trying to push together noise. Everything is in shape with the distributor and solenoids and even if I can't repair it is there a way to nurture it to the mechanics?

Hi Hamish, what you describe is called a 'flaring shift' when revs
don't correlate to vehicle speed due to a slipping auto.
have you rechecked the auto oil level when the engine is running,
sometimes they take a long time to fill because the onboard oil
pump in the auto in very small.

    The oil level was above the max mark when the problem occurred I balanced it so the level reads between min and max but the slipping never stops after first and reverse still

    hi Hamish, sounds like a job for an autotrans specialist

    being a 2005 model vehicle......they all have onboard computors and diagnostic plugpoints. These need to be used by a computor scan tool to find what the fault is. These faults ( called DTC's or diagnostic trouble codes ) will put the repairer right onto the faulty part. Much cheaper and easier to repair. Hope this helps

SOURCE: Renault clio problem

First check to see if the driveshafts are turning, they are the things that stick out either side of the gearbox. start engine put car in gear. and let the clutch up, if you have no drive, open the bonnet and see if the gearbox end of the driveshaft or the wheel end of the driveshaft is moving. if one or the other is (remember to look both sides of the gearbox 2 driveshafts) you have a driveshaft or hub fault. If all is well and nothing is loose or moving the problem is either clutch or internal to the gearbox. this will require removale of the gearbox. approx 5 hours labour remove and refit plus parts required on inspection.

SOURCE: My renault megane automatic is stuck in reverse and won't start

Hi all,
I have a 2002 Renault Megane 1.6 Convertible and experienced exactly the same fault. Needed a team effort but we found a very easy quick fix to this problem. If you take the plastic cover off from under the gear shifter, you will notice a release button covered by a rubber cover. Pressing this release button allows the gear shifter to move from its locked/jammed position. (This is not the fix but it helps with the fix).
If you are fortunate enough to have a 2nd person available, have them poke their head under the bonnet to watch the Gearbox cable move....while you are shifting the gear shifter inside the vehicle. Your partner will see that a cable with a plastic locking device (right hand side of the engine cover) has popped off the shifter for the transmission. Move the shifter until you can physically put the plastic locking device back on the shifter mechanism and your all good to go. No need for that new gearbox that you might have been quoted on!! An easy fix that I am surprised no mechanically minded professional/body in the world has volunteered the solution to. I wonder why????

Good luck!

SOURCE: My 2004 Renault Scenic has an intermittant

I had the same problem for a few years. Had the valve changed undedr warranty, then 1 year later same problem. Because it was out of warranty i put up with it for another year, then i finbally took it in to the dealer and discussed the proiblem. They understood the problem and said that Renault now have an upgraded unit that could be installed. At the same time the computer had to be reset to recognise the the part.One year and $400 later, it is still okay.

My Renaults transmission won't go into second

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

First thing's first. Any time you see a low system voltage code you need to check for proper battery voltage and charging system operation. If the transmission controller isn't getting at least 12 volts, nothing in the transmission will operate properly.
If the alternator is working and no electrical problems are found, check all fuses and fusible links. Also, check for corrosion in the fuse box under the hood.
You will need an additional scan tool to read codes and data from the transmission controller. If you don't have access to one, it would be wise at this point to take the car in. Beyond this point it will be far more time-consuming and expensive to start guessing and throwing parts at the car.
The most likely culprate on the fluid pressure sensor code low system pressure caused by internal transmission wear or damage. A transmission problem is probably why the car went to auction in the first place.

Transmission has been rebuilt. Two weeks late gears would start to grind and has progressively gotten worse

So why are you using the car?

You will have to pull the trans again & go back thru it

It wasn't built right or some other electrical issue,
that caused it to fail wasn't addressed

I changed the batteries in the key fob of my renault megane scenic and now it does not work and i cant start the car, can i bypass this? the year of the car is 1999.

i have not tried this myself but i have been reliably informed that it should work on the 99 renaults

With ignition off, press and hold the key fob button, after about 10 seconds the light on the key will stop flashing, press the key fob button three times and if the key will resyncronise it will at this point operate the locking system.
