700r4 Dust Cover
My '79 has a retrofitted 700r4 in it. There is no dust cover on it currently. It was like that when I bought the car. Someone gave me a cover for it. I have read that some people say it is not necessary and to roll without it as it causes more heat buildup. I live in the country and have about a 200 yard stretch of sand/clay road from my driveway to paved road and on rainy days it gets kind of messy. So I am looking for opinions. Also does anyone know what size bolts are standard for mounting the dust cover?
Thanks, Rick

My trans shop gave me a generic plastic cover for mine. I had to cut it to fit the starter and it had some sheetmetal screws like mentioned above. No I don't know the size. I'd run the cover too.

I have not run a dust cover on ANY tranny in maybe 50 years now, never been an issue and some of the cars ran over 300k miles....
I don't even have one on the motor home...and it sees many miles of Florida sand/clay back roads.....or the '72 vette with 200 4r in it....

I was out of town for a few days and not able to reply back. The only reason I was thinking of putting a dust cover on was I had to get under the car the other day with the motor running. I was checking for collector leaks after putting the top end of my engine back together after having head work done and I am a bit of a klutz sometimes and saw that flywheel and torque converter spinning away and thought to myself that I could see a finger going into there.

I hear you, not any doubt, me too, but I have a suggestion, when you get the car in the air, up on stands....you obtain a large smooth rubber mat, mine came from a old bowling alley, about 1/4" thick and smooth from the ball return/seating section, I slide under and out super easy with that slick rubber under me....much better than any creepy creeper....pretty hard to be klutzy with that ease of movement....
