Vette servo???

[brndns_hoe]

Ok, I think I'm behind the power curve on the corvette servo. I've noticed several guys have installed it. Basically, I know nothing about it. What are the benefits? oh and does it fit the 4.8? tell me whatcha know, I'm clueless lol

[blueflamed03]

yes, fits all 4l60E's, helps firm up the shift points, for firmer shifts...sloooooow shifts from the factory is mainly slippage, which leads to premature tranny failures.

You can get them for about $25 to $40.

[brndns_hoe]

good deal, thanks, any place in particular to get them at?

Here are some install instructions if you need them, there are some on gmfs also.

that's where I ordered mine from :D

[blueflamed03]

PS most tranny shops will install it realitively cheap, good time to change filter and fluid anyway.

[road1will]

So installing a corvette servo should prolong the life of the tranny?

[Chris]

Short answer, yup :waytogo:

[blueflamed03]

So installing a corvette servo should prolong the life of the tranny?

yes sir. Firms up the shift...the lag between shifts, is smooth if your old and want comfort, but that lag is actually the clutches slipping...heat, burn, damage.

[HitandRunDriver]

I loves mine, bought for like 15-20 from oregon performance

[road1will]

did all you guyys install it yourself?

[Chris]

I havent yet but I will be either this weekend or next week, just be sure to seat the snap ring correctly when installing it. Heres a pretty good video, of course you wont need to remove the trans this is just to show you.

I took it in to have the tranny shop do it, change filter, and replace fluid...that's when they saw all the dust in the pan....so complete tranny rebuild...lucky I had 100% warranty :D

[Grebbler]

I did mine and am OK with it.

The biggest pains were the lack of room but it will come out and go in if yer sneaky, getting the servo cover off (mine was at 140k miles), and lastly getting all the parts lined up correctly and compressing the servo cover back on enough to get the snap ring seated all the way.

Take your time, think each move through and confirm each step when done and it's no big deal.

clicking on that link and buying that kit for 15.99 is all i need?

[blueflamed03]

yes sir.

[danimalmax]

looks like i'll be buying that right now lol, im assuming this is the correct one for my 2003 tahoe

[Chris]

sure is man, everything you need is included in that kit.

[danimalmax]

i dont know what i would do without you guys :supergay:

[Chris]

Hahaha same here bro, I would be tearing shit apart without a clue.

[danimalmax]

Okay I got my vette servo today and according to the write ups I need to rub a little fluid on the parts so bare metal doesn't touch bare metal, but where do I get some? Do I have to go buy some from auto zone or something?

any quick answers would be greatly appreciated, then i might start on this tonight

[Sasquatch]

i`ve been thinking about getting a servo for my yukon but i was wondering if i put one in how hard it would shift? when i got my blackbear tune justin maxed out my transmissions line pressure and it now has nice firm shifts. i just wanted to ask if anyone has both a bb tune and a servo and how hard the shifts are with both.

[danimalmax]

good question sasquatch, i'd like to know myself as i will be installing my servo maybe tomorrow or something, then later on i will get a BB tune also

---------- Post added at 10:34 PM ---------- Previous post was at 09:31 PM ----------

hey guys, should i go ahead and add this on with my servo as well?

[withac]

The 'Vette servo will only firm up the 1-2 shift. It won't make it bang, just a real good firm shift. Best bang for the buck mod out there. You should be able to buy the servo and both o-rings for under twenty bucks.

I have the 'Vette servo and BB tune, had the servo before the tune so it was tuned for the servo. If you put a 'Vette servo in it after the tune I think you would want to get a re-tune. Email Justin and ask him. He's real helpful.

I'll let someone else comment on the 4th gear servo, I have talked to some people who installed it also, but I'm not 100% on if its worth it or not. As far as putting some oil on the servo before install, run up to atozone and grab some trans fluid to add

[danimalmax]

Thanks for the responses guys! As for the 4th gear billot servo, there seems to be nothing but positive comments about it over at performance trucks

[06Z71]

i have the fairbanks 1-2 superservo and 4th apply servo, i love them, nice clean quick shifts, no more slip shift

[Drgnblood]

So i just got my servo:hands:....but im on duty again:emotions122:...so i dont know when im going to install.....maybe monday but i will let you guys know how its working...

[SS71]

Got the Superior Transmission super servo set, both 2nd gear and 4th gear apply with the cover. It was the best $110 part I've installed, took the laptop to it and turned the pressures down at part throttle so that 1-2 doesn't slam around town. But on WOT the belt screeches and the tires chirp on the 1-2 then the belt screeches again on the 2-3. Makes the vette servo look squishy. There is positive up and downshifting to all gears. Can't say enough good about it.

[SFBerto415]

I like the smooth shifts in my 'Kon...but yeah they are slooooow shifts. What do you guys mean when you say "Firmer Shifts" Does it get me to go 0-60mph faster?

[blueflamed03]

I like the smooth shifts in my 'Kon...but yeah they are slooooow shifts. What do you guys mean when you say "Firmer Shifts" Does it get me to go 0-60mph faster?the smooth shift you refer to, is actually slippage...slippage is heat on clutch packs, which is bad for tranny.
Firm, firms up the speed and intensity of the shift, less slippage.

[danimalmax]

ok i have a question that can hopefully be answered today

i have a sonnax 4th gear super hold servo that says it can be installed with the corvette servo

it says to change the servo pin or grind the tip of it to achieve desired pin travel
"typically .125" "

do i seriously, literally put on it on my grinder until its an 1/8 of an inch shorter? that just scares me

[tybardy]

doesnt the vette servo only firm up the 1-2 shift... IIRC it doesnt do a thing for the 2-3 or 3-4 shifts.

yea?

anyway what does IIRC mean?

[tybardy]

If I Remember Correctly... lol

i didnt see withac's post, i had only read to the bottom of page 1... i always forget to check the next page before i post... oops

---------- Post added at 10:48 PM ---------- Previous post was at 10:44 PM ----------

the reason i asked is because, and correct me if i am wrong here people... but i think that video is for the wrong servo... am i right?

[danimalmax]

if you mean the vid that chris posted, thats just how to disassemble the whole thing

im not sure how it could be for the wrong servo though

[Fyrcaptain]

Seems like everyone is using an aftermarket vette servo part.....is it cheaper than the OEM vette servo?

Built the same or better?

Thanks

[Mr45]

Just ordered one.

Boy, am I glad I joined this forum. I haven't dropped this much money on my truck in a week in a long time...

[BOSS]

I just ordered the superior shift kit and super servo set, will update everyone...shop does alotta race engines so they won't work on it without hooking it up to the puter first and evaluating the trans while I drive around. They're telling me you may cause the tranny to wear out quicker by changing the servos out because there is a change in the dynamics of the tranny bc of the new servos?

Dang.... Sounds expensive. How much did they quote you for the servo install?

[Grocery Getter]

So I got my servo yesterday and I have my case of RP. I called the transmission shop and they want $100 for the flush and $65 to do the servo.....WTF. I think I will do it myself, who has done it and how did it go?

you cant do the flush youself, that requires some vacuum equipment. However dropping the pan, changing the filter, and adding the RP should be good. (if you have a deep pan i think its like 5 quarts, 3.5 i think for a shallow pan... dont quote me on those though) Im pretty sure this job is a pain in the ass, if i recal, there are a few obstructions making the pan drop difficult

As for the servo, i have not done this yet as i am having some tranny issues i think, so i am holding off, however i have heard that it is a fairly easy and not to time consuming of a project.

Earlier this year, I tried to install my servo on my 2003 Yukon Denali b/c I couldn't get my @#%! heat shield off. So, I've had my servo sitting on my shelf since then. Coincidentally, this week, I called around local transmission shops to get quotes for the install. Here are my findings:
Shop1: $100 (but they barely spoke English, so I'm not sure they knew what the hell I was talking about)
Shop2: Refused to install customer-provided parts due to liability issues.
Shop3: (ie, Moore Buick Pontiac GMC Dealership): $428. No joke.

I guess my servo will be collecting dust for a bit longer.

the corvette servo is actually pretty easy to install, it takes a while, but all you need are a few basic tools, i was scared to do mine at first but once i got started it wasnt so bad, i just did mine last week actually

Once you get to the servo, yes, I've heard that it's fairly easy to install. I'm guessing you're not aware of the heat shield setup on 2003 Yukon Denalis....

I've uploaded a drawing of the heat shield for my YD:
http://i43.tinypic.com/16037mh.jpg

Other than the 2 bolts at the front of the heat shield, notice that there are two holes at the rear portion of the heat shield: Those 2 holes slip into exhaust hangers. If you check out the thread I posted, you'll see the challenge. Try creating a dummy email account with yahoo if you can register with your current email.

From what I hear, only the 6.0's with dual inlet mufflers have the shield that bolts to the exhaust (as well as the trans). The 5.3's have a smaller shield that only bolts to the trans.

i did it last weekend.....watched the video about 40 times just to have it kinda running through my head as i disassembled......easy as hell except its a small area to work in....once you get them all out clean the pieces that will be reused well and the bitch of it...is getting that spring and the fourth apply piston back in correctly...and then get it pushed back in throw all the pieces back in and when you get the cover back on i used the back end of a long flat head and applied pressure so i could get the snaplink back in....and here was my F up...i didnt ensure the snaplink was seated in the groove correctly....i pulled out of the driveway and drove down my street a few feet and it stayed in first....lost most of my tranny fluid and then the rest of it in my garage when i pushed back down my drive....double checked it...got it seated correctly and works great now....no tranny issues and a nice firm shift...just be careful and you should be fine....

its not so bad once u got it all figured out, i even brought my laptop outside with me when i did mine, lol

[Grocery Getter]

Did the servo install this morning. Guys, this is a piece of cake. Biggst PITA is getting the snap ring back it(and not that hard) and getting the heat shield back on after driving arond and getting the cat hot. It took me a little over an hour and that's only because I was taking my my sweet as time so not to f-up. If I were to do it again i think it would take me 30 min or so now that I know what I am doing. If a shop quotes u more than $25-$30 punch them in the mouth.... This was a seriously easy job......

[ELOOSECANNON]

Just ordered my servo today. Can't wait to get it in and try it out.

How do you firm up the other shifts? With another servo along with the vette servo? If so how do they install?

Is there a loss of alot of fluid it the process? Just changed out my filter and fluid and dont want to waste $90.00 worth of RP Trans fluid.

ahh finally i was about to post something similar to this thread, So basically a servo shifts 1-2-3 gears much firmer ? How about the Rev band Does it actually shift each gear on a higher RPM band ? example = 4500-5000 Rpm? What servo do i need for my 06 Tahoe ?

thanks guys this forum is really informative..
