hi, try changing your speedo pick up sensor.your sensor is magnetic, and pick up all the iron filings from the gear-box

Is that a simple job or how much at a garage thank you and where is best place to buy one cheers

hi,yes it is a simple job,but i need more details of your car,eg the make,year,auto or manu.then i can take u through and how to test your switch,maybe it just a clean.

HI It is S reg Alteza auto 1998 back end of that year think that it is a AS which is the same spec as IS thank you for your help.

HI,jack up the drive wheels,remove connector from switch,start the car,and put in 3rd gear,put a ohms meter across terminals,and read off the ohms,u should get 16-17,0 ohms at idle speed in 3rd gear,if not ,the switch is ######.Idon't think it's the gauge,they never go wrong.hope this helps

Hi will i know what the switch looks like it is auto so what about 3rd gear cheers

thank you for your help.

hi,after jacking the car,pull the plugs 1 by 1,and see which plug controls the speedo, and about 3rd, after D or drive u should 3 2 1 . U have P .R .N .D.3 .2 .1,by saying 3rd is so that the g/box don't go into high gear or runing gear.if u only have 2 and 1 then u should have a overdrive button then put it in 2nd.all the best
