Any changes between early A4 and late model A4?
I was just wondering if GM had upgraded any internal parts of the 4L60E transmission from 1997 -2004. My dealership service advisor had told me there had been some new upgrades in the later model A4 s. Truth or BS? Just wondering if anyone out in Corvette land had more info.

The 4L65E has more clutches in the 3-4 clutch pak than the earlier 4L60E. I believe it also has a stronger sun shell. I believe the 4L65E was used in the 03-04 C5s.

The C6 is being sold with the 4L65E or the new 5L80E paddle shift

This quote is from a February, 2003, thread reagarding the 4L65E transmission:
"I was browsing the Gm HP website when I found this info :
24221888 4L65-E Automatic Transmission
GM Hydramatic has baked even more technology enhancements into the automatic transmission line up with the new 4L65E. This transmission, the latest creation from GM Hydramatic Motorsports, is a four speed, offering all the latest heavy duty components to stand up to the power of the LS6-405 HP Corvette engines. Upgrades like induction hardened turbine input shafts, larger intermediate servo, an additional three-four clutch plate. All go toward accommodating higher engine power output. The 4L65E offers optimized performance, fuel economy and increase durability. This sate-of-the-art transmission features the latest heavy duty components and high tech-electronic controls. The advanced electronics controlling the LS6 engine also manages the 4L65E shift points, providing unparalleled performance and durability, P/N 24221888 also includes the torque converter. (No core charge required on this transmission)"

It is as I remember it from back then. I believe they became standard issue on the 2003 models.

When I had a part of my 02 coupe trani go out a year ago, it was the reactor shell.
The GM service manager told me it was a part they reciently upgraded, guess my 02 coupe didn't get the upgrade.
