Any one having problems with the auto shuddering at about 85/90Kph as it changes from 4th gear to auto converter clutch lock up .
I tow trailers & vans a little but only get about 10K out of the trans fluid & filters useing Castrol this time when Valvoline went crappy at about the same mileage & I traced the shudder to the trany & not road surfaces as I first thought .
If I slip it into 3Rd & wind it up to 4K rpm them back into D avoids the problem after about 400Klm of driving on a cool day @ an average of 73Kph acording to ScanGague data .
Oil aint cheep but a change & filter again looks like being un avoidable .
If I could only drain the converter to may help as it holds lots of old oil that mucks up the new stuff real quick .
I will go with the Castrol green gunk again as I have a pressure pot set up with it in to charge the system & can watch the fluid as it moves in & out of the pan so you can get the level spot on with the engine running .
Just wondering thats all .
