Yes & in photo 9 Dan shows which bolts need to be removed with good info in link below. (Dan was only installing spacers though)

And In post 17 my bench photo shows spring /spacer layout well.
Hope this helps...sure fixed my hard shifts w/ code P1811.
Be sure to use Dex VI (6) when refilling.

So from what i'm saw i only install 2 spacers and 2 springs ?

more question , i don't have a torque wrench , how can i know how much to close the pan ?

Once you receive the kit it should be a bit easier to understand.
On the bottom of accumulator housing case you will see 1-2 on one bore & 2-3 stamped on the other bore.
This you need to pay attention to this closely, each bore is a bit different.
The kit comes with new springs & spacers. You will use these.. as in instructions that I posted back on page 2 you might want to print photo 9 & 10 out.
The 2-3 bore receives the 3/4 inch spacer on the bottom, a plain, red,& white spring as well & one half inch (.530) spacer on the top. See layout photo on bench #9
The 1-2 bore also receives a 3/4 inch spacer on the bottom, and a plain and white spring only. (no spacer on top)

Buttoning the pan back up I used a inch lb wrench set at 120 inch lbs.
A torque wrench is the correct method.
I suppose without a torque wrench you could get all the bolts in place tighten then loosely, and then go ahead to where they are snug and 1/4 inch more to tighten.
Not the best method but many use this as a way to snug em up without over tightening.
You may be able to rent a inch lb wrench for this job.
Or if you feel uncomfortable about doing this work, alternatively, you could find a pro shop to complete the shift kit install for you.
Hope this helps.

Thanks a lot Soft Ride !

You are Welcome & I certainly hope this firms up the shifts nicely without the need for replacing the pressure solenoids.
Get 7-8 quarts off Dexron 6. I added 6 and then started the car, drove it short distance and added bit by bit until it was full.
On my PA I believe it took around 7 to 7.4 aprox to hit the full mark on mine.
Yours may vary. Check it hot on level ground running in Park.

thanks , by the way , why Dexron 6 ?
you can explain me the different from dex 3 to 6 ?

Thanks

Some good info on both here.
