Corvette Servos on 98 V6 VT autobox

[grafxworld]

Has anyone done a servo swap ?
is it worth it ?
about how much did it cost you ?
is it something you can do at home without pulling the tranny ? (new to the autobox world , always had stick shifts before)so never played inside one much
one of the guys at holden told me it would fix the slop in the overdrive shifting and make it snappy shifting ? but being a computer controled box I wasn't sure

I don't know anything about it but I have seen them on ebay and according to the person selling them, they can be fitted with the tranny still in the car.

*Goes and grabs servo and instructions from his room*
The trans doesnt need to be removed. You only have to remove the piston cover.
If anyone really wants ill type the instructions out.
Me personally am just going to get preston autos and diffs to fit it when they do the other work for me.

I did it myself with basic tools in about 3 hours. I just followed instructions. While i was under the car i also did the force motor. Now chirps seconds when i put the foot down. Fitting the corvette servo only firms up the shifts slightly.

how much did they cost ?

how much did they cost ?

Around $50-60.

As per the link on ebay I gave earlier, $34.95 at the moment plus $5 postage.

so basically its a shift kit? it provides more oil into the trans makin a harder shift...if so thats a cheap shift kit

I have only got extactors, exhaust and F.I.T rockers. Servo alone wont make you chirp 2nd gear, you need to do force motor as well. The servo is 1 million times easier than force motor.
I got mine from ebay $40 also bought some trans fluid to top up but you hardly loose any fluid. I couldnt believe how easy servo was to do, i was quoted $550 to get it done.

Thanks

um i did my servos 4 yrs ago
best thing i ever done
chirps into second easy and once even into 3rd in the dry
i kow ppl with shift kits and they feel the same but servos are cheeper way of doing it
mine was 180 fitted while getting service on trans
never had a trans prob wiht them in
would i do it again if i got new car hell yeah

ps.Servo alone wont make you chirp 2nd gear, you need to do force motor as well (um mines fine and chirps heaps)

Tell me how it made it chirp the 2-3 shift when the corvette servo only acts on the 1-2 shift?

you do the 3-4 gear change servo as well.....

[daron]

it was the camber of the road and on a bend hehehe and it chirped into 3rd
yeah do them all

I know this champ, but he only changed the 1-2 servo.

I bought my 1-2 corvette servo of him and it's great! Been in there for damn... Maybe 4 or more years! It was one of the best things I did. I also turned up the box pressure and considering it has no shift kit... It shifted freakin awesome!!! Every gear change was solid and no soft slip when at WOT. Still after all this time and a shite load of extremly hard driving it's still behaves like the first day it went in.

Very happy and highly recommend doing this mod!

the corvette servo shown here applies the 2-4 band. the band grabs hold of the reverse input drum, which is how you change to 2nd and 4th gears.

the larger apply area means the shift is made with more force and you it holds the band down harder.

the downside of a harder shift is it obviously loads the transmission a bit more, possibly wearing it faster but who knows by how much? probably not much as the corvette box is the same i would imagine so if it can handle it then so can the commodore one i would assume!

Most people/workshops I have spoken to suggest that the box may last longer, as there is less slip in the gear changes so the clutch packs wont burnout as quick.

Actually improving the way an auto shifts to make quicker changes wears the auto less... but the trade off is it's harsher on you diff, axles and uni-joints.

what you guys said makes sense, now that i think about it again..
