Default Installing a shift kit. 4t65-hd transmission

Time to install that street/strip shift kit? Feeling a little stressed about it? Well, don't. It'* a easy job, just make sure you read and follow the directions very closely. Read, look, read again. Check it a third time just to make sure.

You will need a inch pound torque wrench.

Jack up the front of your car and use jack stands.

Get everything laid out, fluid, the kit, even a extra gasket. Mine had a reusable gasket so I didn't need one.

Locate your tranny pan.

It'* going to be a big mess. Get a large pan to catch the fluid, a few extras are a good idea. Crack the bolts on the pan loose. Loosen the back bolts a bit more so it will drain from that area. When the fluid stops you can start to remove all the bolts.

Wipe it down good. Check the magnet for any metal shavings. If you see a lot of shavings, I suggest not installing the kit at this time.

Remove the 4 bolts holding it in the tranny. One is on the left side and the other three are along the right side

Clean everything up and inspect for damage or wear. Then place on a clean work area and remove the last of the bolts holding the modulator together and open it up

Now reinstall the modulator in the tranny connecting the lines and then line everything up and torque to the correct amount as listed in the directions. As you lift it up each tube will line up.

This piece tends to fall out very easy. So watch for this small piece of metal. Make sure it'* in place before you put the pan back on. It'* on the passenger side. You can see in the pictures above, it was not there. It was replace just before the pan was put back on.

Now with a clicker type inch pound torque wrench torque each bolt to 120 inch pounds. That'* inch pounds, NOT foot pounds

Once the pan is torqued you will need to fill the tranny with the correct fluid. You will do this threw the dip stick tube. You will need a funnel. Make sure you get GM fluid. You will need to add fluid, then start the engine and go threw the gears, then add more fluid and go threw the gears again. It will take some time to fill the tranny back up.

Congratulations, you have now installed your shift kit. Your shifts will be much firmer and quicker.

This kit has also been shown to remove a fair amount of KR.
