Should I put in a shift kit and change all 5 solenoids?

[Sobie]

I'm in the middle of changing the solenoids too fix the p1811 code. Just woundering if i should put in a shift kit to?

YES.....if you're going through all that trouble why half ass it. Drop the $50 and at least get the TransGo shift kit. Very simple and helps firm up the shifts a bit. It's not the most aggressive on the market but is well worth it.

Thank for replying. Is there different levels or spring in the kit?

[GMR Badass]

There are no levels in this kit per say but there is a combination of using old and new springs that will help firm up the shifts a little more over the standard TransGo kit. I'd have to go hunting for the directions but what I've done in both of my GTP's is make the 1-2 and 2-3 solenoids look the same. Use spacers as directed and then use the same combination of springs for both. Then for the 4th accumulator I use the 2 springs in the kit along with the stock spring make a total of 3 springs in the 4th housing.

Here are the instructions for a little bit more of a visual.

Here is where you can see that I use the spacers as directed but use Plain, White, Red for both accumulators. This helps firm up the 1-2 shift just a little. You can also order the 2-3 spring that goes above the piston and use that for the 1-2. GM part number 24203977 is for the spring and will also help firm up the 1-2 shift.


Since I used the Red spring in the 1-2 accumulator what I do is leave the 2 yellow springs that come stock in the 4th accumulator and then add the last remaining yellow springs that comes with the kit. There will end up being 3 yellow springs all said and done.

Here is another good resource if you wanted to go the DIY way.
