As you know in my 1990 classic 3.9 I changed the oil on my autobox which is supposed to done every 25k miles , I did the filter too. after a while it stopped changing up from first in the mornings untill you had done at least a mile which was a problem.
Read on th ashcroft transmissions site that if the oil has not been done as often as it should (ie before I had the car) then you change it it wil stir up all the ****e in the box and block stuff up in the box, including the govenor hence the problem.
I had it changed , £112 for the part £250 labour but to my horror after two weeks of clear running and one moroway trip it has started doing it again, although not as bad , but I can see it fully coming back after another motorway blast which is what seems to do it.
My advice :unless its been service on the button , never change your autobox oil!
It is so annoying as I now have completed all the other jobs on it , some quite big and at least 20 in total.
I have a secondhand box but the same will happen again when I fill it up with new fluid I bet!
And if you have any advice , apart from burning it , which does appeal, it would be most appreciated!
