Fast forward to March 2012

kaboom, broke the stock IS in the GM SRTA trans......so that leads to the epic build.

Started with the Stock 03 trans what had about 66K on when the IS let go.

Found that there are actually output shafts that are used in the 4t65. one is slightly longer
IMG_2225.jpg


and also the longer one also has a rib. its supposedly marked as the HD version, but I am unable to confirm 100%

Intense 300m Input Shaft
IMG_2245.jpg


also the reluctor of the GMR set was Bolted by the previous installer
IMG_2242.jpg


Welded it so it never becomes a problem.

I decided to go with the Raybestos Frictions and Steels over the Borg Warner after spending alot of time on the phone with the companies.

I went with the Stage 1 Red's for Input, and 2nd. Raybestos Z pack for 3rd and Raybestos High Energy for 4th.

Input (5 clutches instead of the stock 4)

Here is the Input module assembled (friction and steels)

Third gear Z pack Module

Fourth Gear Module

Also have a modified 3rd gear clutch piston installed in the drum. Its from the 4T60 Trans and has more surface area and is alittle taller to provide the additional clamping force
 
i dont have pics of the build because its nothing really special, but i did have to take a pic of the GMR one last time.

So after it was all together I modified the rear trans mount with some "poly". As most of you know there is nothing made for some old person Bonneville, so you have to improvise.

New stock Mount
IMG_2247.jpg


and fillling it in
IMG_2253.jpg


IMG_2252.jpg


IMG_2255.jpg


new compared to the old stocker

Also filled in the Drivers side Trans mount with the "poly"

Once the Trans was out, switched the flex to the Meziere Billet unit

As an FYI i also tightened the rear cover bolts. as with every 3800 they were loose
IMG_2285.jpg


IMG_2286.jpg



Also while the trans was out, figured that i would make it pretty. Some rattle can to match the SC and the IC, that was painted in the past.

Installed the false KR kit or whatever, Put a nice blanket on the Case and wrapped the KR sensor too

After all this crap had 2 minor issues, resolved them thanks to Bill.

took the car out.......it was amazing
 


Love the welded ISS reluctor. Looks just like mine, cept big bad chain. FWIW those bolts appear to look like the Dynotech setup I had taken apart here at some point.

Hope it holds up for a ya buddy.
