Hi we own a freelander 1.8 petrol s reg and it's developed a problem with the gears 80% of the time they are fine but if you do several short trips the gears stiffen to the point where the only way you can select 1st gear is to turn the engine off and put it into 1st this doesn't solve the problem just allows you to get home. I seems to be worse when its the weather is hotter. I've taken it to a garage and they seem to think it could be that it has had the wrong gear oil put in it and when it heats up the oil is thickening? I'm not to sure that i agree with this theory. Can anyone shed any light on this for me?
