hi, got a club car ca 295 se, diesel. was working well, started to develop problem with hi- lo selection or 2wd and 4wd selection. setup is called intellitrak. i'm unfamiliar with this setup. club car have given operators manual and parts manual. seems like all the important bits are in front diff. when vehicle driven with gentle acceleration on flat or slight slope downhill you can feel [ through the pedal] the cart "slip" into high range. on flat ground, if accelerator is pushed hard then low range kicks in. top speed about 4 mph. if driven uphill then it will not give anything but low range, no matter what the driver does. vehicle has 78 hrs on it. these problems have been happening fully loaded, now i am getting the same problem with nothing on it, not even the tray. machine turned up missing oil in trans and rear diff. used penrite tractor & transmission oil. finally got manufacturers spec mobil 424, and replaced all diff and trans oils.please help , h
