Tom Waters Race Car Products 904 Trans Shield

Does anyone here have any experience running a Tom Walters (TWRCP, Inc.) transmission shield with a 904 in an A Body Barracuda?

Getting specific with TTI W2 headers and a Turbo Action Shifter.

Information on any experience with a 904 would be still be appreciated.

Thanks!

Bill

I have a CSR shield on my 68 Dart , 408 Small Block , Indy 360-1 heads, TTI W2 headers, 904, with a Turbo Action shifter.

11secdart,

Did you have to modify the trans tunnel any? I have a 69 and had to make a new trans tunnel for the CSR shield.

The new shield is going on a 68.

Thanks,
Bill

...if this is the piece you’re referencing I’d say you’ll be making a new tunnel, and if 9.99 or faster you’ll also have to purchase the “flex plate shield”.

I got 3 CSR shields on A bodies with 904 and all fit without any banging on the trans tunnel...

notched the K member..and it all drops in easy

Only mods to trans tunnel are the access holes I put in so I could reach the top bell housing bolts easier which I have plates to cover. You do have to grind off a few bosses on the bellhousing to clear the shield. I don't have to have the shield as the car is slowed to run mid 11s but have it for safety, it does add about an hour to a trans removal.

Yes that's it. Its a 10 sec car no SFI flexplate or flexplate shield required.

Hopefully my 69 was an exception.

CSR recently refused to re-certify a 904 shield "because it was too old". I have heard others say they will only re-certify twice.

We were going to use a Stroud blanket, they say they have no limits on how many times they will re-certify. However they feel for a Drag Week car there should be at least three inches of clearance between the headers and the trans to keep the blanket from getting cooked. I don't think we have that much.

I recently went from Tubular Automotive headers to TTI s and they fit a lot closer to the trans and shield the bottom strap is really close to the collector. I have a Turbo Action shifter and had to modify the shifter cable bracket clamp as it is exactly were the collector flange meets the exhaust pipes. Seeing how close the shield is to the headers I can't imagine how tight a blanket will be to them. But I am sure there are a lot out there with a TTI blanket combo.

We had TTI on our old W5 combo with a Lofgren blanket so it only had to clear the straps which wasn’t a problem.

I’ve been waiting for my new 904 CSR shield for a few weeks. My 727 one expired a couple years ago and I’ve never recerted it. Hope I can if I go back that direction.

11secdart:
Am I correct that you are using the CSR shield?

If you are running a blanket, run it over the torsion bars. It is usually too close to the headers if you try to wrap the trans.

Yes CSR shield

Surprised that would pass tech, but something to look into.

Have any of you guys had the tech guy go UNDER the car? I have not.

NEVER. Sometimes they'll look under from the rear but that's it.

This is for my car and Tech at drag week last year was pretty tight, they bounced several to slower ETs because of insufficient trans shields or blankets. I know if I have one they won't look, that happens all the time. But not having one is an invite to inspection in my world haha. I should have one anyways for safety but I need one for tech.

On my car you can see the CSR shield from under the hood.

YOu probably can see the SFI stickers from looking under the passenger side, but I doubt if you can see the dates without crawling under with a flash light.

I have had a tech look under the car for a drive shaft loop. Mine is flat on the bottom and he did not think I had one.

There is nothing in the rules that tell you how to mount a blanket. This will protect the driver and that is what matters. I have said this many times before, I seen an explosion with a shield, which did nothing.


That racer almost lost his foot. The shield, what was left, was a yellow ball of yarn (Kevlar). A 904 is safer, but I will never run a shield.

Maybe I am misunderstanding your routing but on my car after going around the torsion bars it would have to go back over the exhaust to tie back up.

Its looking like the CSR Shield is going to be the only option, and with the time at hand we will likely be robbing the current SFI one out of my Dad's car(340Cuda) thanks Dad! lol

I have wrapped it around the bars and then held there by 4 "C" shaped aluminum straps pinched in place.

I do have another strap from one dust cover hole bent to keep the blanket from contact with the driver side header.

I agree with SportF.... I feel a blanket of the proper material will absorb the energy more so than a shield, buuut.... since the rules for sub 10 requires trans and flex plate shield the CSR piece is what I’ll use.

Any suggestions as who might stock an 838 CSR Super Shield (904 SBM)?

CSR is out and delivery to anybody including Summit Jegs and the like is four weeks out. This is from Summit, CSR has not bothered to answer my email. Another reason I would have rather have done something else. However as Clark said the CSR is all that has a chance to fit.

We ended up getting a CSR Shield from A&A. After some heavy 5lb sledge work and lots of air hammer action we managed to stretch the tunnel enough to fit it in. We originally thought we would have to cut and modify the tunnel, I can't believe how far we are able to adjust the tunnel to fit the shield with plenty of clearance. We also had to cut holes for bell housing bolt access because with the shield there was no way to get to the top 2.

Ordered mine July 2.... got a text from summit saying it should arrive this week.
