I have a random delayed 2nd to 3rd shift , generally after coming to rest say at a light .
Its more evident when cold but will still arise randomly when at normal running temps ,
where it would normally change at about 1500 eng rpm under 20 % throttle or less on the odd occasion it will run as high as 2700 rpm, unless I reduce acc and then it will shift
I have been chasing this for months tried various shift schedule changes and Tcc lock up variations which have improved various areas but the underling random behaviour 2/3 remains
Any thoughts would be appreciated !
