A Corvette SERVO is used in the transmission as a 'hill billy' shift kit.

 

Oh, guess you knew that much LOL.

basically. "Corvette" servos are hydraulic, when pressured they clamp down on a clutch or band, then grabs the gear. Basically when you shift from 1st to 2nd it eliminates, or if your running lots of power, helps eliminate slippage. I'd reccomend one, for the price of around $20 it's a good thing to have.

 

Also, your tranny already has a 'servo', vette servos are larger. Billet Servos are bigger and better, as well as stronger and more expensive. Get what you pay for An excellent begginer tranny for moderate mods would be a shift kit, 2nd gear servo, a torque converter, a larger tranny cooler, and complete torque management elimination.

and i need to get all that s**t lol

Its not all mandatory. If you ever swap cams, and decide on a longer duration cam (over 220 duration) , then a TC is mandatory, followed by a larger tranny cooler because even if you have the stocker with the tow package its not enough. Aftermarket TC's are cool as s**t tho, say you get a 3000rpm stall, when your at a stop or some low speed like 10mph and mash the gas, the rpms jump straight to 3000~ rpm, probobly a tad lower like 2800. Plus when you shift into 2nd or 3rd, the rpms don't drop as low. Say you shift at 6000 RPM, (full throttle) and then in 2nd the rpms drop to 3800, with a TC your rpms might drop to 4200. And no in regular driving torque converters dont sit around until that RPM they are rated at, you can drive a car with a higher stall like 3000 around on the streets (with some decent gears like 3.73+). When you get into bigger stalls like 3500+, then daily driving isnt ideal, and big gears like 4.10s++ are highly reccomended.

 

Another plus of that vette servo is this: it doesn't shift like hell at regular part throttle driving, just a crisp quick as hell shift, still light tho. When your at full throttle and shifting, it'll launch you in the seat, no delay. This kind of quick shifting also benefits transmission life. Quick shifts = less heat. Heat kills. Factory slow and sluggish shifts generate more heat. Whatever you do dont go all out and buy a race shift kit, look into regular shift kits aka shift improver kits. Race kits sacrafice tranny life for balls out shifts.

Keep in mind though...Higher stalls will render your rig incapable of towing.

Excellent point I forgot to mention! If your into towing every now and again, I would not get anything more than a Yank ''truck thrust'' 2600, or a Trailblazer torque converter. Good news is the Yank 2600 is only $425, $475~ shipped. You can find trailblazer stalls for cheaper, I think precision industries sells them for 400~~, not completely sure. Some retailers offer core charges, as in yo buy the stall for $400, and send your stocker back to them and get $100 or so back.

 

All in all its on my list of things to do. I don't tow very often at all, and when I do it's because I have a buddy in need..aka a pest

I think I liked it better when it was a "Hill Billy Shift Kit"!
