The transmission teacher from my school also told me that most of our trucks already had vette servos but i didnt believe him because so many poeple have done it...He ended up losing a 15 dollar bet and owed me a set of servo's but i think its definetly worth trying...only takes 30 minutes and we you can spend $300 on a K&N then we can surely spend $15 on some servo's!
Barks better than it bites......
I do not think that the vet servo came in any of the trucks from the factory. I could be wrong but it does come in the Vet, GTO, F-body, and caprice/b-body. The one that most guys confuse with a vet servo is what I refer to as the 4l70E TBSS servo listed below. However I thought I would post a couple pic's of the different servos. Sorry I did not take the measurements of these servos. I did line them up so you guy's could see the various sizes found in GM vehicles. (FROM LEFT TO RIGHT) Here is a photo of a sonnax super hold second servo, the Corvette servo, the 4l70e TBSS servo, a 553 full size truck/car servo, and the 554 servo found in light duty S10 vehicles. All of the servos are OE except for the first servo from sonnax.
Here is a photo of the Sonnax 2nd, the vette 2nd and the 4l70e TBSS 2nd servo.
Hope this helps. Vince B
Goodbye from Vince @ FLT thread.http://www.ls1tech.com/forums/racers...vince-flt.html
cool vince. Thanx. Ill still show mine when I swap them to add to the flavor.
My billets lookd different
Well I checked out the servo I pulled from the transmission(2006 I think, don't have a clue what it came out of) and it looks just like the vette servo pictured in the earlier post. I did buy my trans. used so it's possible that the previous owner could have swapped in a vette servo.
1991 Silverado-L33 5.3L, 212/218 .557 .562 115+4, ASP under drive pulley,180* thermostat, 90mm truck intake w/ LS3 throttle body. Shoenfeld conversion headers and duel Flowmaster exhaust. Performabuilt LVL 1 transmission and 23-2500 stall converter.
I just tried to install my sonnax 2nd and 4th super hold servos...i put it together the way the instructions said and I couldn't push it in far enough to get the spring clip back on so I took it back out and put them next to the stock servos and the sonnax ones are about 1/4" thicker? I tried to use the stock pin and still the same? The servos I got are part #'s 77911-03k(2nd) and 77767k(4th)...are these right? Back to stock for now till I get this straightened out so please help!
sounds like something isn't assembled correctly. You don't have room to spare inside there for 1/4" wider assembly.
See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
I'm pretty sure i put it together right...atleast by the directions that came with the servos. I'm lost!
Try reading the directions again. If you read the directions for the second servo you will read that you might have to modify the the servo apply pin. In most cases I have had to do this and it works. If when you did this with the factory pin I would make sure that the return spring is in it's proper location. Also make sure all the seals are properly installed and that the bore and seals are well lubricated. Maybe try to install the assembly without the seals first. Also make sure that you have the cover for the second servo facing the correct way. VinceOriginally Posted by z71xl

I do see that in the directions but if i take off as much as needed i'll have to take the whole tip of the pin...i dont think something is right!? I'm gonna b pulling the tranny to put my converter in tomorrow night after work so while i have it out i'll try it again. What brand servos were used in the video? Mine look nothing like them...mine are two piece like those but they second one slides over the a hub on the first one
Less than that one most and a lot more than that if you have a factory 6.0...with the %^#$!(* dual in muffler complete with three piece trans heat shield and exhaust bracket set up.
