Hey guys just wanted to let you know that today I just finished the install on my modified valve body from IPT.
I originally took out the valve body and sent it to them Monday. The box got there Tuesday morning. They tried to finish it that day but they just couldn’t get it done in time for the outgoing UPS that day. So they went ahead and finished it up first thing Wednesday and sent it out. I received it this morning and this is what it looked like!

Before all this I had to take the valve body out. By doing this I had to drop the trans pan. Then I had to loosen up the 3 bolts holding the filter on. Then I disconnected all the plugs and they removed the 17 bolts holding the valve body in. If you do this make sure you draw on a piece of cardboard and mark where all the bolts go. There are different lengths throughout the body and if you don’t it will be a pain to install once again.

This is what it will look like when you have removed the valve body.

When removing the valve body you’ll have some parts fall out with it. You’ll have 2 springs a check ball complete with a really small spring. One of the bigger springs are in some kind of cup when it comes out. Take note the smaller spring of the two goes inside the cup that way you done get them mixed up during the install.

Inside the box was also a necessary resistor that I had to install on one of the plugs of the shifting solenoid on the valve body. This resistor I was told effects how that one solenoid acts.

For the install you will need the help of a friend. before you put the valve body back in you’ll need you friend to help place the parts that fell out after removing the body. I ended up lining everything up on the valve body slowly raise the valve body back in while my friend made sure everything was staying lined up. Also take note in the back of the valve body there is the gear selector piston. Make sure you line that up with the shifter mechanism. I didn’t do this and I had to take it all back apart once done and then loosen up the valve body so I could slip it in there! It wasn’t good and I was pisses I forgot to do that!!!! :tap: :tap:
Once I got it up in there my friend went ahead and started a few bolts to hold the valve body in. Then we went around and put the rest in and this is what it looked like.
Torque bolts to 8 ft. lbs

Now to install the resistor you had to tap it into the plug with the green and orange wire (second solenoid on the passenger side toward the bock of the valve body)

Once this was done I put the pan back up and torque the bolts to 67 in. lbf
Then I put ATF in it and started it up checked the fluid and then I was ready to ride!! :P
This file really helped me with taking the valve body apart and install. Also gave me all the torque values and shows the check ball, 2 springs and the cup that falls out with the valve body

can you feel a difference in the way the car drives. I would assume so but is it worth it.

As for regular driving you really cant feel a difference at all. Acually I think it shifts smoother than before but IDK.
But I put it through its first test I did a burn out and thats when it usally hit the revlimiter. But NOT NOW. It was the best burnout I have ever done with the car!! LOL But I can tell now that it acually works and it was so worth it!! LOL
