Just got my first ECVT Justy (1991 4wd) and noticed that it's RPMs run higher than on my 5 speed Justy. Didn't think anything of it until my 5 speed started going about 1000 RPM higher than normal and twice the heat.... Shop says it is the clutch slipping. And $600+ to get it all fixed up. So I got to wondering, what is the normal RPMs for an ECVT Justy?Say... on a flat streach running around 40mph? ADDITIONALLY, I was very happy with how peppy the ECVT is going up hill and it can really go, even in places my 5 speed would have to severely slow down, but it puts the RPMs up around 5000 to do so. So I was wondering if anyone (especially a proffessional mechanic) might be able to tell me if this is okay for say 3 to 5 minutes at this 5000 to 5250 range, or if I should really let off and go slow like in the 5 speed?I always let my 5 speed go slower because it makes me worry when the engine sounds a bit over-worked at 4000 or more, but the ECVT really doesn't sound like it is working very hard until much higher. Just don't want to break my babies by pushing them too hard.

My '91 4wd ECVT spins 4000 RPM at about 74mph on level ground. This is less RPM then my 5 speed Justy's. I've ran it at higher speeds and RPM's for long distances with no ill effects. If you run a good grade of oil and keep it full it really shouldn't be a problem.
I run my vehicles hard quite often and have yet to ever "blow one up". A little maintenance goes a long ways towards longevity.

The cheap list of possabilities: - low atf fluid - Transmission cable (from throttle) out of adjustment - Clutch brushes faulty -

A little maintenance goes a long ways towards longevity. Thanks. I will try it out and see what mine runs when I get down on the highway flat-lands. Anyone know what it should be at 40mph? Makes me feel a little better about running it higher to come up the hills as well. Don't know what kind of oil the dealership put in, so I guess I should probably change it with a good quality to be sure. Will have my hubby check the brushes as well, as soon as he is home for a couple days. In "D" gear. I have only used "Ds" so far for going 4wd very slow up a super steep dirt road near my house. It apears to me that the Ds + 4wd gives you the equivelant of "4wd Low". A super nice thing around here occasionally.

I read the FSM and one of the possabilities is a clipping clutch, but it also says to check the brushes first as it can cause what you are seeing. Simple things first

After getting it to the low lands and checking the RPMs around 70 to 75 mph, they are running a little under 4000. So I am guessing it is fine. It apears that only at the lower speeds that it runs a little higher than my 5 speed.
Yea!
