  1. Chaps I really would appreciate some help if anyone has some expert knowledge of automatic transmissions.
    About 12 months my wife's car (T reg Clio) kept on sticking in 3rd gear, I understand this is what the automatic transmission selects/defaults to when unable to select the right gear. We took it to a garage that specialises in automatics and they said the transmission was knackered and fitted a reconditioned one (for £1200). Now the same problem is happening again but intermittently, we've taken it to a Renault dealer who cannot find any fault with it but it either defaults to 3rd gear or won't select a geat at all when the shift is placed in "drive". Any thoughts or suggestions would be much appreciated.
     
  2. Have you done the obvious and checked the transmission oil level?
     
  3. Good point which I should have mentioned - it can't be done, there is no means of checking this.
     
  4. I once had an auto Renault 21; after getting it I discovered that Renault automatic gearboxes have an awful reputation for unreliability and short lives.

    Check the battery voltage with the engine running. Check the brake light isn't defective, it has an input to the gearbox. Other than that, search the net and best of luck.
     
  5. There must be a dipstick for the gearbox level ,sometimes they are in the engine compartment near the bulkhead ,sometimes a bad earth can affect the gearbox ecu unit ,if it has one ,like one of the previous poster said check the voltage ,really have a good poke around as it probably ony happens when its moving ,so disturb the wires look for shaving as well ,this does happen a lot over the years
     
  6. Google ..renault forums
    every renault problem discussed.
    hope it helps.
     
  7. Sounds like the gearbox ECU is fooked.

    Another mate of mine sells cars.

    PM me for details.
     
  9. @ Joncal - Seriously there is no means of checking the transmission lubricant, no dipstick, nothing. I'll do as you say and have a good poke around the wires etc.

    @ Ordinary Forces - Thanks for that and I've posted a question on that forum now.

    @ The Iron Duke - Thanks for the advice (it made me chuckle)) but right now I can't afford a divroce, a new car or a new wife.

    @ Everyone else thank you for your help.
     
  10. If there is no filler tube/dipstick should be a plug in the transmission casing that you will most likely need to get the car up on a ramp to locate.

    A lot of car makers spout "sealed for life" bollox on autos but without mentioning that the life of such a transmission is usually far shorter than that of the car because 90% of all transmission problems are related to the fliud: either not enough or knackered.

    Even Mercedes tried the "sealed for life" line for a while but were forced to revert to 60,000km fluid changes after the failure rate rocketed.
