GT Selespeed problem
I have the following problem with my GT:
First I noticed the the Selespeed oil was low. I top up with Quaker ATF Dextron III. (red color)
After a few days I noticed the following problem:
With the engine not running I Change from N to 1 and then to 2 and then 3 then 4 and then 5. At the f5 change i get the " Selespeed failure Error" The the error goes off. Again when i shift from 5 , 4, 3 I get the same error. And this happens as i move up and down the shifts.
Now when the engine is on and the car is still, i change shift from N to 1 and then to 2. At the 2 gear it goes immediatly to N and the error appears again. Then the error disapears from the display.
Now When i drive the car I shift from 1 to 2 then to 3 and the error flushes for a second. When i push the brakes and stop , the car goes to N.
I'm taking the car to the dealer on Monday but does anybody had the same problem?
Is it possible to have this problem because i mixed the oils?
