The Corvette Servo Thread to End ALL Threads. - GMC Truck Forum
2008年6月19日 · The purpose of the vette servo mod is to allow the transmission to shift more quickly and efficiently from first to second gear. From the factory, the truck 4L60e's have a smaller servo. The servo is used to apply the 2-4 band in the transmission. Upgrading to the vette servo gives the trans more "holding" power and thus yields a quicker/firmer ...
Longer servo pin??? - GMC Truck Forum
2005年2月15日 · Hit man, do all of these parts (servos, TG HD-2 shift kit, check valve) that go in the 4L60E for the NBS also work in the OBS 4L60E. The transmission are basically the same right. My tranny has like 70K or so on it (lost the first one at 30K) and just I wanna beef it up a tad before I put my whipple on.
Corvette Shift Servo Install w/ pics - GMC Truck Forum
2007年11月1日 · The actual servo itself, a plastic split o-ring, a blue rubber o-ring, and a new pin. Now, the servo is located on the passenger side of the transmission, and may (or may not) have a heat sheild blocking access to it. Mine did, but you should know what a heat sheild is, so I didn't take a picture (ok, I forgot).
4l60e Transgo HD2, Corvette servo installed. First gear...
2010年10月13日 · I installed a Transgo HD2 and Corvette 1-2 servo into my 2003 1500 4l60e. This is my third Transgo HD2 I have installed over the years in various trucks.

4L60e 2-4 Servo Apply Pin stuck in bore - GMC Truck Forum
2015年11月21日 · The only odd thing that I encountered was the 2-4 servo assembly. The cover came off pretty easily after a few whacks of a hammer, but the pistons themselves wouldn't budge. I ended up removing the E clip and taking off the pistons one at a time. The real problem was the apply pin being stuck in its bore.

4L60e slipping issue - GMC Truck Forum
2020年6月2日 · I ordered and installed a Sonnax longer servo pin Part #77787-02K yesterday. I'd estimate (by eye) that the travel was about 1/4" with the first pin and about 1/8" now with the new pin (which is 1/8" longer). I went for a test drive with it today, when it shifted into second gear, it seemed more 'buttery' and a softer type of a shift than before.
