I didn't open the filter, but the magnet was covered and the fluid was full off brass flakes.

Yikes. No wonder people hand over fistfuls of money to transmission shops. Here'* hoping for a flake-free pan when I change my fluid.

I must say, I really don't like torx bolts. Had to drill it out and use a EZout

Nothing worse than a bolt that won't give it up! Nice post Dan.

I've read your transmission install writeup; if there are any special things to note during installation, let us know. Great job so far!

As far as installing it in the car? Not much. Make sure the torque converter is the correct bolt pattern to match the flex plate, that'* about it. If a new transmission has a different gear ratio, a tune will be needed.

All done.

First up today was dealing with the two broken bolts that held the sub frame to the car.

Drilled it out, had to go buy a cobalt drill bit to drill in to hardened steel. Then got the EZout.

Came right out, guess the heat of drilling loosened it up.

Total time was about 13 hours. 3 hours of that was me pulling parts out of the old trans and installing them in the new transmission, like hardened input shaft, hardened 4th gear shaft, and steel channel plate gaskets. So about 10 hours to swap, 8 hours with no problems.

I have a newfound appreciation for transmission shops. Good work by you and the GTX driver.

Now, when you say a new tune is required when changing gear ratios, does it have to be entirely retuned, or just connect a tuner and select the new gear ratio? I ask because if my 4T60-E with the 2.84 gear ratio dies, I'd like to drop in the 3.06 version with minimal fuss.

The gear ratio in the tune will need to be changed. It'* a easy thing to do if you have the software.
