Please i need help,was driveing the car 2day just cruising, and had a nice clear road ahead of me so i says why not and put the foot down,so the foot went down dropped gear and away she went but on reaching the top of her revs the gears didnt change and the revs just stayed high as poss untill i took the foot of the throttell,now i new this was not right at all,so i slowed her down,and things seemed fine,then i was driveing threw a town and notice that my car was not changing gears prop i.e pull away first fine second fine then as slowley increase speed revs go up but car doesnt increase in speed,as if the gears were not ingageing, and now it does this all the time,now ive checked the dip stick for the transmission and there is plenty of oil there but wot i have notice is that when i smell the dip stick it stinks off burning,could this be due to oil being to thin, or is this the thing i dont want it to be,which is gear box away,i must add revers is fine and i have no warning lights on,and just to add this is a n/a auto gear box im talking about.so please help cause i am stumped and stressed.:confused::confused::cry::cry:

Sounds like the box has worn out I'm afraid.

Buring smell from the oil is the usual sign and it starts losing drive in gears.

also dosnt the oil cooler become blocked on autos ???

Change the transmission oil first before you do anything else, drop the oil, i think only 4 or 5 liters will drain out, top it back up and run it around the block, do the same again drop the oil and top it back up. If you are handy with spanners you could drop the oil pan off and flush the stainer. Hopefully this will help but don't thrash it to much and it might last a lot longer.
