Hey all,
I just had my 2014 Cadillac CTS VSport with the Aisin 8-speed serviced with MaxLife ATF and now the transmission is acting funny. Only 44k miles on the car and the transmission calls for GM WS-type fluid. I read on this very forum that WS fluid can be replaced with ATF such as MaxLife (what I usually use), Redline D6, and Amsoil Signature.
I chose the MaxLife route and now the car has a shudder / slight bucking forward and back feeling after some gear shifts have completed and lasts about a second in duration. In addition, when putting down moderate acceleration mid-corner, sometimes the trans feels like it's slipping and as I exit the corner with moderate throttle, the rear end bangs / lurches the car forward aggressively (it has done this twice in 150 miles). I think when this happens, it's either slipping or having a hard time downshifting into gear and when it finally gets into gear, it lurches forward due to the moderate throttle position (the car has 500HP as well so it's not a light thrust forward).
Any thoughts? Valvoline told me this fluid was compatible as well and the GM WS-type fluid is ridiculously expensive. I have just went ahead and ordered the 15 quarts of the WS-type stuff at $11/ quart to have the transmission fluid changed again.
