I performed the transmission pan conversion this weekend. Did it on jack stands. . .tough but doable. After the conversion I attempted to put the bracket that hold the heat shield on. I found the drivers side bolts were tight and impossible to get in. I spent hours trying to get them in. I realize that I could have pulled the front drive shaft off, but that was as much of a pain in my opinion. With surrender 8n sight, I had an idea. If I took my dremel tool and a cutoff blade to the left side of the bracket, I could notch the bracket so it would slide under the bolt. It worked like a dream.
best of all, for future service there is no need to remove the drivers side bracket bolts. Loosen them and the bracket comes free.
attached is a picture for reference.
Hope this help someone.

Do you have a tool that can measure the transmission temp by chance? It would be interesting to see if the shield makes much difference in the temperature. I didn't reinstall my heat shield after changing to a steel pan. Other vehicles that use this transmission with a steel pan typically don't use the heat shield. Seeing this, I assumed it was to protect the plastic pan from heat.
the aluminum shield actually curves up on the passenger side of the trans protecting it from the heat coming off the cat which is pretty close on that side.
I would put it back on. I would venture to say those other vehicles don’t have a cat in the same proximity.

If you think of it sometime, check to see what the trans temp is and ambient air temp during your check. I've been running it without the shield for the last 14k miles... but i see your point. Just would be interesting to see the difference. Looks like mine runs around 189 to 192 on the flats in 90 degree ambient temp. It popped up to 203 on the same day on a long 6% grade up I70 towards the Continental divide which didn't really surprise me. Thanks!
I thought about getting a surface thermometer before I made the swap as I wanted to make sure the temperature of the transmission was right as I added fluid. I didn't get that done. . .but the transmission was warmed up when I added the fluid.
Runs and shifts silky smooth . . .
You need to know what the temperature is when filling these transmissions. If it is too warm, you'll under fill it. I'd rather have a little too much in it than not enough.
