Important:
This bulletin mainly deals with the features of the new Touch Activated Power feature of the 4T65E transaxle, which is only available on the
supercharged Grand Prix. However, it is important for technicians to familiarize themselves with the differences between the TAP-equipped transaxle
and the non-TAP equipped transaxle. There are several components of the transaxle that are unique to TAP. These components are NOT
INTERCHANGEABLE with the same components on a non-TAP equipped 4T65E transaxle. If the correct parts are not used, serious driveability
concerns could result.
The purpose of this bulletin is to introduce new features of the 4T65E transaxle for the 2004 model year. Valve Body, Spacer Plate and Channel Plate.
Valve Body, Spacer Plate and Channel Plate
The internal changes to the 4T65E transmission are in the valve body, spacer plate and the channel plate. These parts are unique to the Touch Activated
Power (TAP)-equipped 4T65E transmission. (TAP is only available on supercharged Grand Prix models.) A non-TAP transmission has a different valve
body, spacer plate and channel plate. DO NOT MIX THE PARTS.
If incorrect parts are installed, there will be shifting concerns. Any test drives should include TAP-Shift(TM) operation.
