Transgo Recalibration Kit Install
I just bought the Recalibration kit. I hope to get the Corvette Servo and boost valves soon.(Pro-built, I will be calling soon) I was just wondering how difficult it is to install all of this. I do a lot of work on my car(i.e. headers and exhaust), but I have never messed with transmissions. The kit consists of a lot of springs and **** poor instructions. Is there anyone out there that has installed this kit (other that the professionals)? I called around and only one place would even touch this install and their charge was ~$250. What do you guys think?

The kit can be a PITA to install especially if you have never messed with a valve body before. If that $250 includes fluid I'd say go for it, if you cant afford it plan on a full days work and take your time. If you have messed with a valve body before it should only take about 3 hours or so.
$250 seems a little pricey, but if you have no clue about transmissions, it may be a wise investment. TransGo tells there distributers NOT to sell to consumers, so I don't know how you got it. I'm not trying to be a jerk when I say that, but I have seen to many people damage their tranny, then blame the kit when something went wrong
If you can get your hands on the video that I hear is out there somewhere, it would be a definate plus.

I have the video in my kit. It's very entertaining but not extreamly detailed. I have not installed the kit yet either. But I got a pric of $140 from a shop around here.

I recently installed a TransGo reprogramming kit. Prior to that my total experience with
automatics was changing the filter. Having worked on every other part of a vehicle
I figured that a little-ole-auto wouldn't be much trouble.
It was an experience, no doubt about it. A world of springs, valves, wires, and snail-trails.
In the end it all worked rather well. I didn't even have to drop the pan a second time.
Once the kit arrived I read & re-read the instructions. With the factory shop manual and
the instructions I went through all of the parts figuring out what was what.
The baggies & labels came next. The parts associated with each step was placed into
a baggie and labeled to the step number. This paid off as I had a baggie with a spring
in it left over. Hmm, forgot a step (change spring). As I worked on each step I checked
and double checked. Drill size, hole to drill, spring to use, ordering/direction of parts. Used
a magic marker (sharpie) on the separator plate & marked the holes to be drilled or filled.
Then double checked it against the instructions. And triple checked it once I was done.
If you can follow instructions and are good with hand tools, then you should be able to
do the install properly. It took ~8 hours to do the work. This included doing some
things twice. Such as after replacing the shift shaft seal, I needed to take the
mechanism apart again to get the rod engaged into the manual shift valve (after installing valve body).

SSC, maybe thats the difference, none of mine have the video, and I was told when I got "on board" w/ my wholesaler that I could re-sell whatever I wanted, but had to put a disclaimer on the TransGo kits. I'm sure al the "Jr" kits are sold everywhere, and I guess all the "reprogramming" kits for the general public come with a video.
