my 2007 GMT900 had a 60e.Not a 65 or 70 but a 60. Your's may too. Look on the side of the trans and see if M30 is cast on it. Look in the RPO code list in the glove box.

Red the numbers on the actual piston and cover are production numbers. Not the part numbers. This is a misconception often found in the industry so I wanted to point it out.
Here is the number for the vet servo assembly. Vince
gm # 8642079 for the piston and 8673039 is for the cover.
Goodbye from Vince @ FLT thread.http://www.ls1tech.com/forums/racers...vince-flt.html
Hey Vince, can you measure one of the Vette servo pistons and post what the diameter is so they can tell if the one stock in their transmission is the same as the Corvette servo or not?

2009 CHEVROLET 1500 with a MONSTER 4.8 between the frame rails!!
Tuned by LSX Powersports ~ 4.10 ~ JBA Shorties ~ 4" Inlet/Outlet Spintech ~ Airaid Coldair
CST 3.5" Spindles ~ Camburg Upper Control Arms ~ 2.5" CCM ~ FFR Tie Rods
Full Throttle Suspension 3" Lift Blocks ~ Soft 8s wrapped in LT285/70/17 Silent Armors
The difference is the degree of holding power. Both will firm up your 3-4 shift. The Superior Fairbanks is more extreme than the Sonnax and is usually more appropriate for the dragstrip. The Sonnax is a great in-between (between stock and Superior). Read about all the servos here.
I'm running both Sonnax servos with the Sonnax chromemoly servo pin and have no complaints. The Sonnax 2nd gear servo is a nice improvement over the Vette servo I was using before.
