I used 3/4" closed cell foam, of the type normally used to insulate
HVAC ducting. Bought a big roll for $4 at an industrial
place here in town. Blocks excessive temps, dampens noise. Flexible,
and can be bonded to the trans cover with standard 3M Spray Adhesive
which you can find at WalMart or similar. Cuts with scissors.
If you don't have a recycling/reuse center, I would imagine any
HVAC supply place would have it. Or ask the guy who services the
furnace/AC in your house.
It worked so well, when I re-did the interior last year I pulled up all

with 1/2" closed-cell foam I bought from the same place. Took me just a

and backed them with the foam.
The noise reduction is significant. I can actually hear the radio.
Also, I replaced the seal around the trans cover - that does a world of

the top of the front of the old cardboard covers tends to fold over
letting in noise, heat, water and all manner of annoyances. Back when I

One last thing if finances are tight and that cardboard cover is more
and holes than cover - a friend of mine and I covered his busted-up
cover with cheap fiberglas. We covered the cover with the matting, and
just poured on the resin, one half at a time. Total cost was about $15.
but it worked.
Oh, and other other thing - after I got that ABS cover and had it
to my satisfaction, I took the cardboard cover into the back yard, put
a bit of kerosene on it, and had a celebratory bonfire while I had a
