Hi as you may have seen on my previous threads I am experiencing heavy gear changes what I have now noticed is that it appears to do a double change into top gear the first change is when I get a very heavy change and the revs drop and then go back up and the second change is reasonably smooth I am thinking of taking the valve block out to see if I can see anything wrong I have also sent for some Lucas transmission fix to try if it will improve the changes Has anyone any ideas what might be causing this problem
