<OT> : CVT Auto Transmissions
One for the petrol heads who own vehicles fitted with CVT tranmissions. A word of advice, whatever you do, don't use the normal ATF fluid. I've got a Nissan ( my favourite car, after giving up on the pajero ) and I found a supplier who had the original NS-1 oil for the gearbox. The CVT transmission oil needs to be changed every 60,000Kms and there is a special process of doing it. FYI. -- The EL_Diablo is a metaphor...

This is one field i like to gather info - very poor in auto mobiles - Aki could we have more technical explanation if you have one? I could be a victim you know.

@Thuo, what would you like to know? ( you opening a floodgate now... ) :-) -If you meant to ask about a CVT auto transmission, it's fitted more and more on Nissan saloons, selected X-trails etc. Toyota also catching up on this technology, I saw this gearbox on an Avensis. Here is a explanation : http://en.wikipedia.org/wiki/Continuously_variable_transmission . What does the CVT-fitted vehicle feel like = its almost similar to sitting in a plane on take-off from stationary. You do not feel the gear changes at all. The CVT auto drive presents instant acceleration, holds revs within the 3,000-4,500rpm, does not have any D-3-2-L manual selection of the normal auto gearboxes. It does provide a sport mode which holds the engine revs between 4,500-6,000rpm upto 100Km/h, after which it would be adviceable to switch to normal CVT drive. - With the CVT auto transmission fitted to a matched normal aspirated but flowed engine ( like the Nissan QR20DE engine = 2,000cc = 145bhp ), it will produce much better throttle responses and on average a better fuel consumption. - If you meant to ask about the CVT Auto Transmission Oil type, then the best way to check the original is printed on the gearbox dip-stick. The Nissan saloon uses this green-colour fluid which is specially designed for the CVT gearbox and must be changed as per mileage below. I managed to get the service manual which explains the oil change procedure. Incase you own a Nissan with the CVT drive, here is the following procedure that may work: a) Warm up car by driving about 10 minutes ( ensure the temp is between 50c-80c deg ) b) Drain from the return pipe, while re-filling at charge side, while the engine is idling. c) After the change, check the oil level. Warm up car, short drive for 10 minutes and check the "hot" level on the gearbox dip-stick. HTHs. Rgds. On Tue, Nov 15, 2011 at 4:27 PM, Thuo Wilson <lixton@gmail.com> wrote:

Now this is knowledge I find totally OT but incredibly uselful. Thanks Aki. On Tue, Nov 15, 2011 at 5:10 PM, aki <aki275@gmail.com> wrote:

I have a Honda Civic with a cvt gearbox would your supplier have that in stock and for how much and what's the procedure to change it? Thanks and regards, Ian On 15 November 2011 22:24, ty <tyruskam@gmail.com> wrote:

@ty, you are welcome. :-) @Ian, on the Honda gearbox dipstick, there should be a tag or print of the type needed. Let me know and I can check with the supplier. On the Honda approved change procedure, I'm not familiar with this but I'll ask around. On Tue, Nov 15, 2011 at 10:53 PM, Ian Macharia <machaian@gmail.com> wrote:

@Ian, while you check the fluid number, here is a link to Honda's CVT. Nicely done graphics to appreciate the CVT too. http://www.honda.co.nz/technology/driving/cvt/ On Tue, Nov 15, 2011 at 11:14 PM, aki <aki275@gmail.com> wrote:

if you own a honda civic 96-2000 i have the maintenance manual. It has all those details On 11/15/11, aki <aki275@gmail.com> wrote:

Very nice, thanks Aki. I don't like nissans though (not for what i know) but for what people say (they are not good - but i have never found one explaining the technicalities as to why a toyota is better than nissan!) Could someone explain. BTW this is not OT, This is techie stuff. WIlson./

@Wilson, thnks for the questions. I'm not an auto professional but loved the industry. The Toyota is a very good car and mind set in Kenya is primarily parts availability, costs and that they hold market resale value due to popularity. Whatever the Toyota has, the Nissan has the same too. Now I cannot write further for Toyota but let me do for Nissan Primera. One thing I like about Nissan is that they are similar to Subaru, Honda, Mitsubishi and don't change models very frequently, which maintains a useful parts supply line for a number of years. Nissan and Subaru and otehrs too try and create cars a bit more innovatively, within the same engine class. For example, the 2.0litre QR20DE Nissan engine pushes out 145 bhp. Without even putting large marketing stickers on the engine like VVTi etc, the QR20DE engine is fully variable value timings sytems, chain driven cam-shafts, full alloy engines. Nissan's approach to the interior produces a centre console display with plenty of passenger space. On the Primera, Nissan outsourced it to French designers and they came up with a unique car. Let us do the visual aspects and costs. Both are sporty versions, if using a 2litre engine and CVT transmission : Nissan Primera : Shape 2004 onwards : http://www.youtube.com/watch?v=uGJ4CPb27Ms&feature=related http://www.youtube.com/watch?v=o9CfKoP7bMw&feature=related Toyota Avensis :Shape 2004 onwards : http://www.youtube.com/watch?v=D66gsBKB68M&feature=related http://www.youtube.com/watch?v=XaUYNqYMDtM&feature=related You guess is as good as mind on Toyota popularity. :-) -- **Sent from my Microsoft/Intel based computer.

What I know, is that a Nissan Caldina will groan if you filled it with cabbages, but a Toyota Probox will handle the load well. However, why Probox are driven worse than matatus may have little to do with the manufacturer.
