I have a 1997 Grand Scenic with 50,000 on the clock. When the car has been running for a while - the gearbox becomes stiff, and you have to place it in gear (notably from 2 to 3). The problem is exacerbated in hot weather, and also depends on the time spent running. So in summer it starts after aXXXXX in winterXXXXX We have changed the gearbox oil (seems to have helped temporarily) and the gear cables (no effect). Anyone any ideas? Gearbox is stiff after a drive - but relaxes when left, and after 2 hours is back to normal.
Model: Grand Scenic

I am still awaiting an answer. My account tells me an expert has replied - but all i can see is the moderator comment.
Sorry - I made a mistake in my question above - the car is a 2007 Grand Scenic not a 1997 one!
Hello and Welcome to justanswer...First let me apologise, I see you have had a wait on your question..With the situation you have, you have progressed a lot already in what you have done...and I'm afraid that this the narrows the fault down to the transmission itself being faulty. This is im afriad, something I have personally seen more than once on these gearboxes. Now ,it depends how you want to progress with it.. I know some who have just gone ahead of changed the gearbox , but others I know have had some success in changing the oil for a different type than that of the recommended..and that beings thinner, high quality fully synthetic oil. I can't recommend this officially you understand, but I do know as mentioned, of success. Basically what's happening is the selector rings ( cogs ) which are like a sheath affair..a circular hollow cog ,they go out of shape ,ever is slightly, but enough to cause the stiffness that you describe. ( i seen this with a full strip of the transmission ) the use of the oil as described above does help so long as the cogs in question are not fractured. That said, if they are fractured, they tend to be stiff and awkward all the time, heat / cold/ time of driving making no difference. I can't recommend a specific oil, suffice it say that I know the oil mentioned above was a motor oil ( engine )....so I tell you that as FYI. Ultimately of course ,the answer is a replacement or a rebuilt transmssion ...as mentioned above, it depends , people are different and will opt for different approaches...so I have given you all on this as it were to fully explain the situation...So either way as above is the way forward on this one, I'm sorry it's not especially good news..but that is the situation you have on this one I'm afraid..I'm very pleased to have helped you... By all means get back to me if you need / wish...Meantime, please do click one of the OK smiley faces for me... Thank you. While the question may close, you can if you wish / need , come back to me at anytime . .. clicking the OK smilies don't close you out...Kind Rgds , MIKE

Many thanks for the advice, I've had a chat with out local garage (who did the oil and the cables previously) and they concur with your advice - and I'm now considering my options vis a vis different oil or new gearbox (I've found a supplier who will sell a new gearbox for 320 quid which is a better price than i thought so am leaning toward that!).
I'll rate the answer to ensure payment goes through. I'll put good on the basis that we need to do the work to confirm the problem - but If i can I'll rate as excellent once the work is done and the problem sorted.
