Its supposed to help with 1-2 and 2-3. For 4th gear you can get a billet servo which will help you hold overdrive longer, which is better for highway driving. It also keeps your torque converter at full engagement when the PCM kicks it on, instead of the sloppy, half engagement that it has from the factory at times. I would have already done that if it wasn't a hundred bucks, lol

Thanks I'm going to do this asap.

Thank you for this write up! I was about to drop the trans to get this done, since it seems most of the full sized truck guys think that's mandatory for the little Blazer. A buddy at work said the same thing. I read other write ups but none as reassuring as this for the small trucks.

Have my parts ordered and going to get this done soon. I know it's not an immentent doom situation, but the wife who normally drives it is constantly complaining about how she feels it's going to leave her stranded or something because it shifts a tad lazy.

I'll post back with results. Thanks again!

Thanks, I got my vette servo a few days ago. Will be putting it in today after seeing your how to post.

The trans in my 1996 Tahoe was rebuilt right before I bought it, and I hated the mushy shifts. My friends 96 chevy truck shifts the same way. I put the Corvette servo in yesterday, and now I love it. The pictures you took were very good, and made the job very easy (about an hour) Thanks.

which position do the scarf(cut) O-rings go?
