2010 Rogue awd hangs in 1st gear sometimes now going down the road rpms climb to5-6 thousand and the car is not going any faster let off and it pulls normal.

Take it to a garage and check the OBD codes.

Faulty abs

sounds like either the syncromesh is wearing on 1 of the gears, or a clutch release bearing, this can stay like this for thousands of miles & just get noisier, or go bang at anytime?

sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

its most def a purely transmission issue i believe its the solenoids. have it taken to a reputable trans shop near and have them diagnose it with there speciall code reader.

Sounds like a shorted or sulfated battery to me.

First I need to ask is it a 4 speed or a 3 speed transmission. If it's a 4 speed when driving down the road pull it from drive to third gear. You shpuld hear the engine speed up if it does not then that means you have on 4th gear and you will have to take it to a transmission shop. If it's a 3 speed then just count the shift points if all 3 gears are present then drive down the road and see if the van goes into tcc. When you mean the rpms are high how high are they.

Check your transmission fluid level. If the filter has never been changed, now is a good time to replace the fluid and filter.

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.

Try some Seafoam brand trans tune it might help.
Even if it dosen't it's a cheap experment.
