hi and thankyou the weight of my caravan is 750kgs bout with the bits we carry around may be 850 total weight and not sure what color atf is it seem to drive ok without any weight but lost kickdown now and like i already said now and then like a clutch slip then very high revs before changeing gears :coffee:

Hi, Maybe the kick-down cable is worn/frayed? But I would check your gearbox fluid soo as you can for quality and level... :) Des. . . ;)

lockut button 

do i use it rite from the start or when the car har got to its top speed and then push the button whist the car is in motion as the woman i bought the car of told me it dropped me down a gear when towing and going up hill i didnt get a owner manual with the car ..........the answer to how many miles its done is 160,000 :car::cellphone::lightbulb:

Hi, With the lock out button applied (turned on) there will be an orange light on the dash will show and it will prevent the car going into O/D. This can be turned on at any time as O/D only kicks in when the car hits 3rd gear... With 160k miles on the car, it may be prudent to consider a auto transmission oil change... Depends on the condition nof the oil in there at the moment, but I would give it serious consideration.. Des. . . ;)

atf change 

thankyou is it a job for the garage only or is it a job i could do for my self as by the looks of things it could do with a change as its a muddy brown colour and woud i need any specail tools and is the drain plug easy to find and get at ?:lightbulb::money:

Hi, Have a read through this topic: .... About half way down Tim describes how he changed his.. No going via the sump plug, just disconnected the connection to the radiator and used a couple of pipes. Measure it in and measure it out. Make sure to get the right fluid... Des. . . ;)
