Automatic gear change speeds

Hello peeps

I have been unsuccessful on-line to find any information about the automatic gearbox on my 2014 Jimny. Specifically at what speed or revs the car changes up each gear. The reason I want to know this information is because my little Jimbo revs its heart out in 3rd and will not change into 4th unless I reach 55mph. I want to know if this is normal and/or can the point where it changes gear be adjusted?

Fanks, Phil

I don't drive out automatic often enough to tell you that precise speed but it's not as high as 55 once it has warmed up. It will however hold revs for a while if it's cold.

Phil,
If no one else replies I will give you a more detailed reply with the information you ask for tomorrow. I have a 2004 automatic which, once the engine warms up to “ normal” seems to change up and down in the 2500 to 3000 rpm. Of course until the engine is warm it will not change up into top so you can, if you are not careful, get the revs up above 3000 rpm in 3rd gear.
Not being too technical....there will be someone else on hear who is, my understanding is that the automatic gearbox will only fully work once the gearbox oil has reached the correct operating temperature. There is, I presume, a sensor in the gearbox to detect when this temperature is reached. Anyway I will get back tomorrow with the Rev figures that you ask for. Good luck sorting this out.

It depends on several factors. How hard you are pressing the accelerator, how much load is on the transmission (going up hill or towing for example) and of course transmission temperature. Other than changing the oil every few years there is little that can or needs to be done to the transmission. Bear in mind that shifting up too early is undesirable, given the Jimny engine is not very powerful and the power it does make is made at high rpms. I've never driven mine slowly but I know that if you hold your foot to the floor and it will change at close the red line, and it is nice and eager to change down under load.

As said above it depends on the load the engine is under, but on my 2004 automatic on a flat road with two adults it seems to change at10/15, 20/25 and 35/40. The engine has to warm.
Hope this is some help to you.
