A few quick Corvette Servo and 4L65E Trans Questions- Please Help!

[kxdan01]

I've got a 03 Silverado SS with the LQ9 6.0 engine and its all wheel drive with a 4L65E Transmission- will the Corvette servos work for my application? If So, please help me understand this, I'm a pretty good mechanic but have never done any major transmission work(just maintenence). So does the Corvette servo just basically make it shift quicker, or harder/firmer/faster?- I know when I stomp my truck to the floorboard it accelerates pretty hard but the 1-2 shift is so slow its pathetic, it feels like it takes forever to shift from 1-2 and I want to correct this issue. And just to clarify- there is nothing wrong with the transmission or anything, it has always been that way but I've had enough of it! All of my programming is stock also, the truck has no modifications other than the exhaust. I will be getting it tuned very soon and doing a few other things but for now I just wanna fix this slow 1-2 shift. Thanks in Advance for your help and I've been looking at this site since I got my Silverado SS, this is a great site guys and I look forward to the help. Also, in all of the catalogs/parts books I always see stuff for the 4L60E trans but never see anything listed for a 4L65E- I know the 65E is just a slightly upgraded 4L60E so will the 4L60E parts interchange with mine, like transmissin pans, filter kits, stall converters, etc. Thanks again! Also, if its gonna help me can someone point me in the right direction as to where I can buy a Corvette Servo and whatever else I need for the install? A parts list would be great. Also- does anyone make a transmission cooler kit that comes as a package deal to specifically fit my truck- I wanna upgrade my tiny little stock cooler, and also would a higher capacity transmission pan help lower my trans temps very much?

The very first thing you should do is get a Nelson Tune.

It will help you a bunch and then if you still feel you need to go into the trans do so, but I doubt you will.

As far as the trans cooler kit, its pretty simple. Most people do it them selves.

Thanks, will the tune address that slow shifting? How much HP/TQ does it add? I know you can't say for sure but just a close estimate would be nice? Do you have a Nelson Tune? If so how much diffrence did it make? I mean can you really feel it? Did you pick up any gas mileage? I had my Cobra(not supercharged) custom tuned with SCT software and couldn't even feel it, but that's totally different I guess. I wonder about having the Torque Managment removed, at least during Tow/Haul mode, it just sucks for me because I live so far away from Nelson Tuning and I'd really like to have it done on a dyno to see what kind of diffrence it makes and to make sure the air/fuel ratio is safe and all of that good sh*t but nobody around here has an All Wheel Drive Dyno, I wonder if Nelson does? I also don't like the idea of removing my computer to ship off to Texas and have to wait on it to get back here because I know it'll probably take the better part of a week and this is my only vehicle right now. But I've read nothing but good things about Nelson Tuning. Also- is it really worth all of the expense and trouble to put a set of Longtube Headers w/ off Road Y Pipe on my 03 SS? I wonder if I could get 50hp between the tune/full exhaust/and a good Cold Air Intake Setup?

Holy questions batman.
Yes (most or all of it, it depends on what your looking for, and its really an opinion thing.)
HP/TQ gain will depend on mods.
I have a different tune but it was a mistake, all following tunes will be from nelson. To put it shortly, I will be buying a few with in the next 6 months.
Yes you will feel it.
Mileage depends on the skinny peddle, if you drive the same it will gain mileage.
SCT is different.
They mail you a computer, you install, then you ship back your stock one or pay a core charge and keep your stock one.
The track times, seat of your pants, and smile on your face is way more important than dyno numbers.
I havent heard of anyone unhappy with longtubes.
I would think 50 hp at the crank is realistic.
